Scientists Now Know: We're Not From Here!
Summary & comments by Dan Eden for Viewzone
Imagine the shock of growing up in a loving family with people you call "Mum" and "Dad" and then, suddenly, learning that you are actually adopted!
This same sense of shock came as scientists announced that the Sun, the Moon, our planet and its siblings, were not born into the familiar band of stars known as the Milky Way galaxy, but we actually belong to a strange formation with the unfamiliar name of the Sagittarius Dwarf galaxy!
How can this be?
Using volumes of data from the Two-Micron All Sky Survey (2MASS), a major project to survey the sky in infrared light led by the University of Massachusetts, the astronomers are answering questions that have baffled scientists for decades and proving that our own Milky Way is consuming one of its neighbors in a dramatic display of ongoing galactic cannibalism. The study published in the Astrophysical Journal, is the first to map the full extent of the Sagittarius galaxy and show in visually vivid detail how its debris wraps around and passes through our Milky Way. Sagittarius is 10,000 times smaller in mass than the Milky Way, so it is getting stretched out, torn apart and gobbled up by the bigger Milky Way.

Sagittarius is 10,000 times smaller in mass than the Milky Way, so it is getting stretched out, torn apart and gobbled up by the bigger Milky Way.
A new infra red digital survey of the entire sky was made in 2003. Teams from the universities of Virginia and Massachusetts used a supercomputer to sort through half a billion stars to create a -- NEW STAR MAP showing our Solar System (yellow circle) to be at the exact nexus crossroads where two galaxies are actually joining.
"It's clear who's the bully in the interaction," said Steven Majewski, U.Va. professor of astronomy and lead author on the paper describing the results.
"If people had infrared-sensitive eyes, the entrails of Sagittarius would be a prominent fixture sweeping across our sky," Majewski said. "But at human, visual wavelengths, they become buried among countless intervening stars and obscuring dust. The great expanse of the Sagittarius system has been hidden from view."
Not any more. By using infrared maps, the astronomers filtered away millions of foreground stars to focus on a type of star called an M giant. These large, infrared-bright stars are populous in the Sagittarius galaxy but uncommon in the outer Milky Way. The 2MASS infrared map of M giant stars analyzed by Majewski and collaborators is the first to give a complete view of the Milky Way galexy's meal of Sagittarius stars, now wrapping like a spaghetti noodle around the Milky Way. Prior to this work, astronomers had detected only a few scattered pieces of the disrupted Sagittarius dwarf. Even the existence of Sagittarius was unknown until the heart of this nearest satellite galaxy of the Milky Way was discovered by a British team of astronomers in 1994.
Here's an animation of the "marriage".
The fact that the Milky Way is seen in the sky at an angle has always puzzled astronomers. If we originated from the Milky Way, we ought to be oriented to the galaxy's ecliptic, with the planets aligned around our Sun in much the same angle as our Sun aligns with the Milky Way. Instead, as first suggested by researcher Matthew Perkins Erwin, the odd angle suggests that our Sun is influenced by some other system. Together with data from the Two-Micron All Sky Survey we now know what it is. We actually belong to the Sagittarius Dwarf galaxy.
"We sifted several thousand interesting stars from a catalog of half a billion," said co-author Michael Skrutskie, U.Va. professor of astronomy and principal investigator for the 2MASS project. "By tuning our maps of the sky to the 'right' kind of star, the Sagittarius system jumped into view."
We are from another galaxy in the process of joining with the Milky Way. The Milky Way is actually not our parent galaxy. The mystery of why the Milky Way has always been sideways in the night sky has never been answered -- until now.
"This first full-sky map of Sagittarius shows its extensive interaction with the Milky Way," Majewski said. "Both stars and star clusters now in the outer parts of the Milky Way have been 'stolen' from Sagittarius as the gravitational forces of the Milky Way nibbled away at its dwarf companion. This one vivid example shows that the Milky Way grows by eating its smaller neighbors."
The study's map of M giants depicts 2 billion years of Sagittarius stripping by the Milky Way, and suggests that Sagittarius has reached a critical phase in what had been a slow dance of death.
"After slow, continuous gnawing by the Milky Way, Sagittarius has been whittled down to the point that it cannot hold itself together much longer," said 2MASS Science Team member and study co-author Martin Weinberg of the University of Massachusetts. "We are seeing Sagittarius at the very end of its life as an intact system."
Does this mean we are at a unique moment in the life of our galaxy? Yes and no.
"Whenever possible, astronomers appeal to the principle that we are not at a special time or place in the universe," Majewski said. "Because over the 14 billion-year history of the Milky Way it is unlikely that we would just happen to catch a brief event like the death of Sagittarius, we infer that such events must be common in the life of big spiral galaxies like our own. The Milky Way probably dined on a number of dwarf galaxy snacks in the past."
On the other hand, Majewski and his colleagues have been surprised by the Earth's proximity to a portion of the Sagittarius debris.
"For only a few percent of its 240 million-year orbit around the Milky Way galaxy does our Solar System pass through the path of Sagittarius debris," Majewski said. "Remarkably, stars from Sagittarius are now raining down onto our present position in the Milky Way. Stars from an alien galaxy are relatively near us. We have to re-think our assumptions about the Milky Way galaxy to account for this contamination."
The new findings will help astronomers measure the total mass of the Milky Way and Sagittarius galaxies, and probe the quantity and distribution of the invisible dark matter in these systems.
"The shape of the Sagittarius debris trail shows us that the Milky Way's unseen dark matter is in a spherical distribution, a result that is quite unexpected," Weinberg said.
"The observations provide new insights into the nature of the mysterious dark matter," said Princeton's Spergel. "Either our galaxy is unusual or the dark matter has richer properties than postulated by conventional models."

Implications in Global Warming?
It has been postulated that this is the real reason for both global warming since higher energy levels of the Milky Way are almost certain to cause our Sun to burn hotter and emit higher energies. Indeed, temperatures have been seen to rise on virtually all the planets in our system. This seems quite apart from any local phenomenon like greenhouse gases etc.
This grand turning is possibly the root cause for the discontinuation of the Mayan calendar (the most accurate on the planet) because the 'read-point' of the Pleiades star cluster, which many believe the calendar was based upon, can no longer be a constant as we begin to steer away from the earlier predictable movements.
Other changes happening in our system
The "marriage" of our birth galaxy with our new adopted Milky Way galaxy is causing energy shifts that are obvious just about everywhere. Here are some changes being watched by scientists:
* A growth of dark spots on Pluto.
* Reporting of auroras on Saturn.
* Reporting of Uranus and Neptune polar shifts (They are magnetically conjugate planets), and the abrupt large-scale growth of Uranus' magnetosphere intensity.
* A change in light intensity and light spot dynamics on Neptune.
* The doubling of the magnetic field intensity on Jupiter (based upon 1992 data), and a series of new states and processes observed on this planet as an aftermath of a series of explosions in July 1994 [caused by "Comet" SL-9]. That is, a relaxation of a plasmoid train which excited the Jovian magnetosphere, thus inducing excessive plasma generation and it's release in the same manner as Solar coronal holes inducing an appearance of radiation belt brightening in decimeter band (13.2 and 36 cm), and the appearance of large auroral anomalies and a change of the Jupiter - Io system of currents.
Update Note: A stream of ionized hydrogen, oxygen, nitrogen, etc. is being directed to Jupiter from the volcanic areas of Io through a one million amperes flux tube. It is affecting the character of Jupiter's magnetic process and intensifying it's plasma genesis.[Z.I.Vselennaya "Earth and Universe" N3, 1997 plo-9 by NASA data]
* A series of Martian atmosphere transformations increasing its biosphere quality. In particularly, a cloudy growth in the equator area and an unusual growth of ozone concentration.
Update Note: Mars Surveyor Satellite encountered an atmospheric density double that projected by NASA upon entering a Mars orbit. This greater density bent one of the solar array arms beyond the full and open stop. This combination of events has delayed the beginning of the scheduled photo mission for one year.
* A first stage atmosphere generation on the Moon, where a growing natrium atmosphere is detected that reaches 9,000 km in height.
* Significant physical, chemical and optical changes observed on Venus; an inversion of dark and light spots detected for the first time, and a sharp decrease of sulfur-containing gases in its atmosphere.
* A Change in the Quality of Interplanetary Space Towards an Increase in Its Interplanetary and Solar-Planetary Transmitting Properties.
When speaking of new energetic and material qualities of interplanetary space, we must first point out the increase of the interplanetary domains energetic charge, and level of material saturation. This change of the typical mean state of interplanetary space has two main causes:
* The supply/inflow of matter from interstellar space. (Radiation material, ionized elements, and combinations.)
* The after effects of Solar Cycle 22 activity, especially as a result of fast coronal mass ejection's [CME's] of magnetized solar plasmas.
What does it all mean?
We of the overarching Sagittarius Dwarf Elliptical Galaxy have finally come down next to, and even with the massively powerful spiral armed equatorial plane of the Milky Way Galaxy.
In our movement through space, our Earth has now fully begun to respond to the more powerful galactic energies and electro-gravitational bias of the massive Milky Way. We have reached the higher energy equatorial disc region of the massive spiral arm. We have now been "adopted" by a new system, a stornger and more powerful system, and we can expect changes on almost every level of energy.
Whatever these changes are, they are all part of the natural birth, death, rebirth and transformation of the cosmos. As our knowledge of the universe grows, we cannot but understand how much we do not understand. Such is life.

The History of Urantia
PAPER 57
THE ORIGIN OF URANTIA
IN PRESENTING excerpts from the archives of Jerusem for the records of Urantia respecting its antecedents and early history, we are directed to reckon time in terms of current usage--the present leap-year calendar of 3651/4 days to the year. As a rule, no attempt will be made to give exact years, though they are of record. We will use the nearest whole numbers as the better method of presenting these historic facts.
When referring to an event as of one or two millions of years ago, we intend to date such an occurrence back that number of years from the early decades of the twentieth century of the Christian era. We will thus depict these far-distant events as occurring in even periods of thousands, millions, and billions of years.
1. THE ANDRONOVER NEBULA
Urantia is of origin in your sun, and your sun is one of the multifarious offspring of the Andronover nebula, which was onetime organized as a component part of the physical power and material matter of the local universe of Nebadon. And this great nebula itself took origin in the universal force-charge of space in the superuniverse of Orvonton, long, long ago.
At the time of the beginning of this recital, the Primary Master Force Organizers of Paradise had long been in full control of the space-energies which were later organized as the Andronover nebula.
987,000,000,000 years ago associate force organizer and then acting inspector number 811,307 of the Orvonton series, traveling out from Uversa, reported to the Ancients of Days that space conditions were favorable for the initiation of materialization phenomena in a certain sector of the, then, easterly segment of Orvonton.
900,000,000,000 years ago the Uversa archives testify, there was recorded a permit issued by the Uversa Council of Equilibrium to the superuniverse government authorizing the dispatch of a force organizer and staff to the region previously designated by inspector number 811,307. The Orvonton authorities commissioned the original discoverer of this potential universe to execute the mandate of the Ancients of Days calling for the organization of a new material creation.
The recording of this permit signifies that the force organizer and staff had already departed from Uversa on the long journey to that easterly space sector where they were subsequently to engage in those protracted activities which would terminate in the emergence of a new physical creation in Orvonton.
875,000,000,000 years ago the enormous Andronover nebula number 876,926 was duly initiated. Only the presence of the force organizer and the liaison staff was required to inaugurate the energy whirl which eventually grew into this vast cyclone of space. Subsequent to the initiation of such nebular revolutions, the living force organizers simply withdraw at right angles to the plane of the revolutionary disk, and from that time forward, the inherent qualities of energy insure the progressive and orderly evolution of such a new physical system.
At about this time the narrative shifts to the functioning of the personalities of the superuniverse. In reality the story has its proper beginning at this point--at just about the time the Paradise force organizers are preparing to withdraw, having made the space-energy conditions ready for the action of the power directors and physical controllers of the superuniverse of Orvonton.
2. THE PRIMARY NEBULAR STAGE
All evolutionary material creations are born of circular and gaseous nebulae, and all such primary nebulae are circular throughout the early part of their gaseous existence. As they grow older, they usually become spiral, and when their function of sun formation has run its course, they often terminate as clusters of stars or as enormous suns surrounded by a varying number of planets, satellites, and smaller groups of matter in many ways resembling your own diminutive solar system.
800,000,000,000 years ago the Andronover creation was well established as one of the magnificent primary nebulae of Orvonton. As the astronomers of near-by universes looked out upon this phenomenon of space, they saw very little to attract their attention. Gravity estimates made in adjacent creations indicated that space materializations were taking place in the Andronover regions, but that was all.
700,000,000,000 years ago the Andronover system was assuming gigantic proportions, and additional physical controllers were dispatched to nine surrounding material creations to afford support and supply co-operation to the power centers of this new material system which was so rapidly evolving. At this distant date all of the material bequeathed to the subsequent creations was held within the confines of this gigantic space wheel, which continued ever to whirl and, after reaching its maximum of diameter, to whirl faster and faster as it continued to condense and contract.
600,000,000,000 years ago the height of the Andronover energy-mobilization period was attained; the nebula had acquired its maximum of mass. At this time it was a gigantic circular gas cloud in shape somewhat like a flattened spheroid. This was the early period of differential mass formation and varying revolutionary velocity. Gravity and other influences were about to begin their work of converting space gases into organized matter.
3. THE SECONDARY NEBULAR STAGE
The enormous nebula now began gradually to assume the spiral form and to become clearly visible to the astronomers of even distant universes. This is the natural history of most nebulae; before they begin to throw off suns and start upon the work of universe building, these secondary space nebulae are usually observed as spiral phenomena.
The near-by star students of that faraway era, as they observed this metamorphosis of the Andronover nebula, saw exactly what twentieth-century astronomers see when they turn their telescopes spaceward and view the present-age spiral nebulae of adjacent outer space.
About the time of the attainment of the maximum of mass, the gravity control of the gaseous content commenced to weaken, and there ensued the stage of gas escapement, the gas streaming forth as two gigantic and distinct arms, which took origin on opposite sides of the mother mass. The rapid revolutions of this enormous central core soon imparted a spiral appearance to these two projecting gas streams. The cooling and subsequent condensation of portions of these protruding arms eventually produced their knotted appearance. These denser portions were vast systems and subsystems of physical matter whirling through space in the midst of the gaseous cloud of the nebula while being held securely within the gravity grasp of the mother wheel.
But the nebula had begun to contract, and the increase in the rate of revolution further lessened gravity control; and erelong, the outer gaseous regions began actually to escape from the immediate embrace of the nebular nucleus, passing out into space on circuits of irregular outline, returning to the nuclear regions to complete their circuits, and so on. But this was only a temporary stage of nebular progression. The ever-increasing rate of whirling was soon to throw enormous suns off into space on independent circuits.
And this is what happened in Andronover ages upon ages ago. The energy wheel grew and grew until it attained its maximum of expansion, and then, when contraction set in, it whirled on faster and faster until, eventually, the critical centrifugal stage was reached and the great breakup began.
500,000,000,000 years ago the first Andronover sun was born. This blazing streak broke away from the mother gravity grasp and tore out into space on an independent adventure in the cosmos of creation. Its orbit was determined by its path of escape. Such young suns quickly become spherical and start out on their long and eventful careers as the stars of space. Excepting terminal nebular nucleuses, the vast majority of Orvonton suns have had an analogous birth. These escaping suns pass through varied periods of evolution and subsequent universe service.
400,000,000,000 years ago began the recaptive period of the Andronover nebula. Many of the near-by and smaller suns were recaptured as a result of the gradual enlargement and further condensation of the mother nucleus. Very soon there was inaugurated the terminal phase of nebular condensation, the period which always precedes the final segregation of these immense space aggregations of energy and matter.
It was scarcely a million years subsequent to this epoch that Michael of Nebadon, a Creator Son of Paradise, selected this disintegrating nebula as the site of his adventure in universe building. Almost immediately the architectural worlds of Salvington and the one hundred constellation headquarters groups of planets were begun. It required almost one million years to complete these clusters of specially created worlds. The local system headquarters planets were constructed over a period extending from that time to about five billion years ago.
300,000,000,000 years ago the Andronover solar circuits were well established, and the nebular system was passing through a transient period of relative physical stability. About this time the staff of Michael arrived on Salvington, and the Uversa government of Orvonton extended physical recognition to the local universe of Nebadon.
200,000,000,000 years ago witnessed the progression of contraction and condensation with enormous heat generation in the Andronover central cluster, or nuclear mass. Relative space appeared even in the regions near the central mother-sun wheel. The outer regions were becoming more stabilized and better organized; some planets revolving around the newborn suns had cooled sufficiently to be suitable for life implantation. The oldest inhabited planets of Nebadon date from these times.
Now the completed universe mechanism of Nebadon first begins to function, and Michael's creation is registered on Uversa as a universe of inhabitation and progressive mortal ascension.
100,000,000,000 years ago the nebular apex of condensation tension was reached; the point of maximum heat tension was attained. This critical stage of gravity-heat contention sometimes lasts for ages, but sooner or later, heat wins the struggle with gravity, and the spectacular period of sun dispersion begins. And this marks the end of the secondary career of a space nebula.
4. TERTIARY AND QUARTAN STAGES
The primary stage of a nebula is circular; the secondary, spiral; the tertiary stage is that of the first sun dispersion, while the quartan embraces the second and last cycle of sun dispersion, with the mother nucleus ending either as a globular cluster or as a solitary sun functioning as the center of a terminal solar system.
75,000,000,000 years ago this nebula had attained the height of its sun-family stage. This was the apex of the first period of sun losses. The majority of these suns have since possessed themselves of extensive systems of planets, satellites, dark islands, comets, meteors, and cosmic dust clouds.
50,000,000,000 years ago this first period of sun dispersion was completed; the nebula was fast finishing its tertiary cycle of existence, during which it gave origin to 876,926 sun systems.
25,000,000,000 years ago witnessed the completion of the tertiary cycle of nebular life and brought about the organization and relative stabilization of the far-flung starry systems derived from this parent nebula. But the process of physical contraction and increased heat production continued in the central mass of the nebular remnant.
10,000,000,000 years ago the quartan cycle of Andronover began. The maximum of nuclear-mass temperature had been attained; the critical point of condensation was approaching. The original mother nucleus was convulsing under the combined pressure of its own internal-heat condensation tension and the increasing gravity-tidal pull of the surrounding swarm of liberated sun systems. The nuclear eruptions which were to inaugurate the second nebular sun cycle were imminent. The quartan cycle of nebular existence was about to begin.
8,000,000,000 years ago the terrific terminal eruption began. Only the outer systems are safe at the time of such a cosmic upheaval. And this was the beginning of the end of the nebula. This final sun disgorgement extended over a period of almost two billion years.
7,000,000,000 years ago witnessed the height of the Andronover terminal breakup. This was the period of the birth of the larger terminal suns and the apex of the local physical disturbances.
6,000,000,000 years ago marks the end of the terminal breakup and the birth of your sun, the fifty-sixth from the last of the Andronover second solar family. This final eruption of the nebular nucleus gave birth to 136,702 suns, most of them solitary orbs. The total number of suns and sun systems having origin in the Andronover nebula was 1,013,628. The number of the solar system sun is 1,013,572.
And now the great Andronover nebula is no more, but it lives on in the many suns and their planetary families which originated in this mother cloud of space. The final nuclear remnant of this magnificent nebula still burns with a reddish glow and continues to give forth moderate light and heat to its remnant planetary family of one hundred and sixty-five worlds, which now revolve about this venerable mother of two mighty generations of the monarchs of light.
5. ORIGIN OF MONMATIA--THE URANTIA SOLAR SYSTEM
5,000,000,000 years ago your sun was a comparatively isolated blazing orb, having gathered to itself most of the near-by circulating matter of space, remnants of the recent upheaval which attended its own birth.
Today, your sun has achieved relative stability, but its eleven and one-half year sunspot cycles betray that it was a variable star in its youth. In the early days of your sun the continued contraction and consequent gradual increase of temperature initiated tremendous convulsions on its surface. These titanic heaves required three and one-half days to complete a cycle of varying brightness. This variable state, this periodic pulsation, rendered your sun highly responsive to certain outside influences which were to be shortly encountered.
Thus was the stage of local space set for the unique origin of Monmatia, that being the name of your sun's planetary family, the solar system to which your world belongs. Less than one per cent of the planetary systems of Orvonton have had a similar origin.
4,500,000,000 years ago the enormous Angona system began its approach to the neighborhood of this solitary sun. The center of this great system was a dark giant of space, solid, highly charged, and possessing tremendous gravity pull.
As Angona more closely approached the sun, at moments of maximum expansion during solar pulsations, streams of gaseous material were shot out into space as gigantic solar tongues. At first these flaming gas tongues would invariably fall back into the sun, but as Angona drew nearer and nearer, the gravity pull of the gigantic visitor became so great that these tongues of gas would break off at certain points, the roots falling back into the sun while the outer sections would become detached to form independent bodies of matter, solar meteorites, which immediately started to revolve about the sun in elliptical orbits of their own.
As the Angona system drew nearer, the solar extrusions grew larger and larger; more and more matter was drawn from the sun to become independent circulating bodies in surrounding space. This situation developed for about five hundred thousand years until Angona made its closest approach to the sun; whereupon the sun, in conjunction with one of its periodic internal convulsions, experienced a partial disruption; from opposite sides and simultaneously, enormous volumes of matter were disgorged. From the Angona side there was drawn out a vast column of solar gases, rather pointed at both ends and markedly bulging at the center, which became permanently detached from the immediate gravity control of the sun.
This great column of solar gases which was thus separated from the sun subsequently evolved into the twelve planets of the solar system. The repercussional ejection of gas from the opposite side of the sun in tidal sympathy with the extrusion of this gigantic solar system ancestor, has since condensed into the meteors and space dust of the solar system, although much, very much, of this matter was subsequently recaptured by solar gravity as the Angona system receded into remote space.
Although Angona succeeded in drawing away the ancestral material of the solar system planets and the enormous volume of matter now circulating about the sun as asteroids and meteors, it did not secure for itself any of this solar matter. The visiting system did not come quite close enough to actually steal any of the sun's substance, but it did swing sufficiently close to draw off into the intervening space all of the material comprising the present-day solar system.
The five inner and five outer planets soon formed in miniature from the cooling and condensing nucleuses in the less massive and tapering ends of the gigantic gravity bulge which Angona had succeeded in detaching from the sun, while Saturn and Jupiter were formed from the more massive and bulging central portions. The powerful gravity pull of Jupiter and Saturn early captured most of the material stolen from Angona as the retrograde motion of certain of their satellites bears witness.
Jupiter and Saturn, being derived from the very center of the enormous column of superheated solar gases, contained so much highly heated sun material that they shone with a brilliant light and emitted enormous volumes of heat; they were in reality secondary suns for a short period after their formation as separate space bodies. These two largest of the solar system planets have remained largely gaseous to this day, not even yet having cooled off to the point of complete condensation or solidification.
The gas-contraction nucleuses of the other ten planets soon reached the stage of solidification and so began to draw to themselves increasing quantities of the meteoric matter circulating in near-by space. The worlds of the solar system thus had a double origin: nucleuses of gas condensation later on augmented by the capture of enormous quantities of meteors. Indeed they still continue to capture meteors, but in greatly lessened numbers.
The planets do not swing around the sun in the equatorial plane of their solar mother, which they would do if they had been thrown off by solar revolution. Rather, they travel in the plane of the Angona solar extrusion, which existed at a considerable angle to the plane of the sun's equator.
While Angona was unable to capture any of the solar mass, your sun did add to its metamorphosing planetary family some of the circulating space material of the visiting system. Due to the intense gravity field of Angona, its tributary planetary family pursued orbits of considerable distance from the dark giant; and shortly after the extrusion of the solar system ancestral mass and while Angona was yet in the vicinity of the sun, three of the major planets of the Angona system swung so near to the massive solar system ancestor that its gravitational pull, augmented by that of the sun, was sufficient to overbalance the gravity grasp of Angona and to permanently detach these three tributaries of the celestial wanderer.
All of the solar system material derived from the sun was originally endowed with a homogeneous direction of orbital swing, and had it not been for the intrusion of these three foreign space bodies, all solar system material would still maintain the same direction of orbital movement. As it was, the impact of the three Angona tributaries injected new and foreign directional forces into the emerging solar system with the resultant appearance of retrograde motion. Retrograde motion in any astronomic system is always accidental and always appears as a result of the collisional impact of foreign space bodies. Such collisions may not always produce retrograde motion, but no retrograde ever appears except in a system containing masses which have diverse origins./////////////////////////////
PAPER 15: Section 3.
The Superuniverse Of Orvonton
------------------------------------------------------------------------
P167:4, 15:3.1 Practically all of the starry realms visible to the naked eye on Urantia belong to the seventh section of the grand universe, the superuniverse of Orvonton. The vast Milky Way starry system represents the central nucleus of Orvonton, being largely beyond the borders of your local universe. This great aggregation of suns, dark islands of space, double stars, globular clusters, star clouds, spiral and other nebulae, together with myriads of individual planets, forms a watchlike, elongated-circular grouping of about one seventh of the inhabited evolutionary universes.
P167:5, 15:3.2 From the astronomical position of Urantia, as you look through the cross section of near-by systems to the great Milky Way, you observe that the spheres of Orvonton are traveling in a vast elongated plane, the breadth being far greater than the thickness and the length far greater than the breadth.
P167:6, 15:3.3 Observation of the so-called Milky Way discloses the comparative increase in Orvonton stellar density when the heavens are viewed in one direction, while on either side the density diminishes; the number of stars and other spheres decreases away from the chief plane of our material superuniverse. When the angle of observation is propitious, gazing through the main body of this realm of maximum density, you are looking toward the residential universe and the center of all things.
P167:7, 15:3.4 Of the ten major divisions of Orvonton, eight have been roughly identified by Urantian astronomers. The other two are difficult of separate recognition because you are obliged to view these phenomena from the inside. If you could look upon the superuniverse of Orvonton from a position far distant in space, you would immediately recognize the ten major sectors of the seventh galaxy.
P168:1, 15:3.5 The rotational center of your minor sector is situated far away in the enormous and dense star cloud of Sagittarius, around which your local universe and its associated creations all move, and from opposite sides of the vast Sagittarius subgalactic system you may observe two great streams of star clouds emerging in stupendous stellar coils.
P168:2, 15:3.6 The nucleus of the physical system to which your sun and its associated planets belong is the center of the onetime Andronover nebula. This former spiral nebula was slightly distorted by the gravity disruptions associated with the events which were attendant upon the birth of your solar system, and which were occasioned by the near approach of a large neighboring nebula. This near collision changed Andronover into a somewhat globular aggregation but did not wholly destroy the two-way procession of the suns and their associated physical groups. Your solar system now occupies a fairly central position in one of the arms of this distorted spiral, situated about halfway from the center out towards the edge of the star stream.
P168:3, 15:3.7 The Sagittarius sector and all other sectors and divisions of Orvonton are in rotation around Uversa, and some of the confusion of Urantian star observers arises out of the illusions and relative distortions produced by the following multiple revolutionary movements:
1. The revolution of Urantia around its sun.
2. The circuit of your solar system about the nucleus of the former Andronover nebula.
3. The rotation of the Andronover stellar family and the associated clusters about the composite rotation-gravity center of the star cloud of Nebadon.
4. The swing of the local star cloud of Nebadon and its associated creations around the Sagittarius center of their minor sector.
5. The rotation of the one hundred minor sectors, including Sagittarius, about their major sector.
6. The whirl of the ten major sectors, the so-called star drifts, about the Uversa headquarters of Orvonton.
7. The movement of Orvonton and six associated superuniverses around Paradise and Havona, the counterclockwise processional of the superuniverse space level.
P168:11, 15:3.8 These multiple motions are of several orders: The space paths of your planet and your solar system are genetic, inherent in origin. The absolute counterclockwise motion of Orvonton is also genetic, inherent in the architectural plans of the master universe. But the intervening motions are of composite origin, being derived in part from the constitutive segmentation of matter-energy into the superuniverses and in part produced by the intelligent and purposeful action of the Paradise force organizers.
P168:12, 15:3.9 The local universes are in closer proximity as they approach Havona; the circuits are greater in number, and there is increased superimposition, layer upon layer. But farther out from the eternal center there are fewer and fewer systems, layers, circuits, and universes.

P465:6, 41:10.1 Some of the variable stars, in or near the state of maximum pulsation, are in process of giving origin to subsidiary systems, many of which will eventually be much like your own sun and its revolving planets. Your sun was in just such a state of mighty pulsation when the massive Angona system swung into near approach, and the outer surface of the sun began to erupt veritable streams -- continuous sheets -- of matter. This kept up with ever-increasing violence until nearest apposition, when the limits of solar cohesion were reached and a vast pinnacle of matter, the ancestor of the solar system, was disgorged. In similar circumstances the closest approach of the attracting body sometimes draws off whole planets, even a quarter or third of a sun. These major extrusions form certain peculiar cloud-bound types of worlds, spheres much like Jupiter and Saturn.
P466:1, 41:10.2 The majority of solar systems, however, had an origin entirely different from yours, and this is true even of those which were produced by gravity-tidal technique. But no matter what technique of world building obtains, gravity always produces the solar system type of creation; that is, a central sun or dark island with planets, satellites, subsatellites, and meteors.
