2 Billion Alien Earths Could Exist In Our Galaxy


Our galaxy might be a bit more crowded than we've ever thought.

A new study by the scientists at NASA's Jet Propulsion Laboratory in Pasadena, CA suggests that one out of every 37 to one out of every 70 sun-like stars may have an Earth-like planet in it's orbit, according to Space.com. These planets are at such a position that liquid water could exist on the planet's surface, according to the researchers.

That means there could be billions of Earth-like planets just in the Milky Way Galaxy.

In February, the Kepler telescope identified 1,200 possible alien worlds, 68 of which were about the size of Earth. The new data, again collected by the Kepler telescope, suggests that 1.4 percent to 2.7 percent of all stars in the galaxy could be expected to have Earth-like planets in the appropriate zones, according to UPI.

But there may be even more life out there, in other galaxies.

From Space.com:

    "This means there are a lot of Earth analogs out there -- two billion in the Milky Way galaxy," researcher Joseph Catanzarite, an astronomer at NASA's Jet Propulsion Laboratory, told SPACE.com. "With that large a number, there's a good chance life and maybe even intelligent life might exist on some of those planets. And that's just our galaxy alone -- there are 50 billion other galaxies."

The same scientists predict that about 12 Earth-like worlds will be discovered after three to four years of Kepler data is analyzed, according to Space. Four have already been seen in the few months of data already released.

Looks like NASA is almost up for an Adamski-type revelation.

I'm sure their excuse will be like... we didn't want to cause public panic or get all "BROOKINGS-INSTITUTE" on us by saying their study concluded that certain civilizations had broken up and dissolved when exposed to different cultures disseminating  different ideas.

The only problem will be the alethephobes*  who won't be able to accept it.

It's great that there are more earths to choose from, though, when this one blows itself all to hell!

Venus is nice and Satrun is too.

Mars and Mercury have surfaces that are unliveable but they are well equipped underground.

Neptune, Uranus,  Nibiru, and Pluto.  Nice warm climatic surfaces.  The Kuiper Belt re-radiates photons like a photon capacitor so the outer planets have livable climates too.
