Radio Bursts: Mysterious 'Lorimer' Waves From Another Galaxy Baffle Astronomers (VIDEO)

It came from a galaxy far, far away.

A single, sudden burst of radio waves. And then it was gone.

The so-called 'Lorimer' burst was spotted in 2007 -- and has been baffling scientists ever since.

"This is something that's completely unprecedented," Duncan Lorimer, the West Virginia University astrophysicist who made the discovery told Space at the time.

Today, the 'burst' is not alone. Indeed, four more identical flares have been observed, according to Popular Mechanics.

"You have to look at the sky for a very long time to find these," British astrophysicist Dan Thornton, who observed the fresh, fleeting bursts, told the magazine. "The reason that we’re detecting them now is we've simply looked long enough."

Thornton and his University of Manchester team published their findings in Science magazine, noting "the bursts’ properties indicate that they are of celestial rather than terrestrial origin."

The cause of the flares, which appear for only scant milliseconds, remains unknown. But researchers suggest an "explosive event" may be involved, as the bursts appear to be one-time events.

While the exact origins of the radio waves are also difficult to pinpoint in the vast expanse that is space, scientists are certain that the signals traveled a staggering distance.

Thornton suggests they took half the universe's lifespan to get here. And, as Science News reports, they disappeared almost instantly upon arrival.

What may yet linger, however, is the wealth of data these flickering heralds bring.

Scientists say the bursts may shine light on the vast, previously unknown tracts of space that separate the galaxies.

"Staggeringly, we estimate there could be one of these flashes going off every ten seconds somewhere in the sky," research team member Simon Johnston said in Global Times.

"With the ability to detect these very fast sources we are opening up a whole new area of astrophysics."

Listen To These Eerie 'X-Files' Sounds Recorded At The Edge Of Space

What does the edge of space sound like? Pretty darn strange. Just have a listen to these acoustic signals recorded in the stratosphere some 22 miles above Earth's surface (above).

At frequencies below 20 hertz, these so-called "infrasounds" are too low for the human ear to hear. But sped up by a factor of 1,000, they sound "kind of like 'The X-Files,'" Daniel Bowman, a graduate student in geophysics at the University of North Carolina at Chapel Hill and the leader of the recording effort, told Live Science.

Up, up, and away. For the research, conducted as part of NASA's High Altitude Student Platform program, Bowman attached microphones to a helium balloon and then sent it on a 9-hour flight above New Mexico and Arizona, according to Live Science. The flight took place on Aug. 9, 2014.

It's not the first time recordings of atmospheric infrasound have been made. But in many previous efforts, the recordings were made on the ground -- and extraneous noise was a problem.

"I decided to try putting microphones on balloons to reduce the wind noise (the balloon moves at the same speed as the wind) and to see if I could find sounds that don't make it down to Earth," Bowman told The Huffington Post in an email.

Decoding the mystery. As for what the new stratospheric sounds could be, Bowman and his colleagues are still working to interpret them -- though they do have some guesses.

"We think that they are probably a combination of thing happening far away (commercial aircraft, waves in the Atlantic ocean, air turbulence, even air conditioners in buildings) and things happening nearby (cables vibrating on the balloon and cosmic rays hitting the sensor)," he said in the email.

If you were hoping the signals might be evidence of aliens, you're out of luck.

"There is no evidence to suggest that these signals are from extraterrestrial sources," Bowman said. "Sound cannot travel through space, so whatever is generating it must be located within about 140 km (approximately 90 miles) of the Earth's surface."

The research was presented in Pasadena, Calif. on April 23 at the annual meeting of the Seismological Society of America.

sounds from interstellar space sent back by voyager.

"NASA's Voyager 1 spacecraft captured these sounds of interstellar space. Voyager 1's plasma wave instrument detected the vibrations of dense interstellar plasma, or ionized gas, from October to November 2012 and April to May 2013."

from http://www.space.com/22781-voyager-1-interstellar-space-sounds-video.html a little more on voyegar 1's 37 year 12 billion mile trip into interstellar space.
