EARTHSONG: A NASA spacecraft has recorded audio-frequency radio emissions coming from Earth. Some say the signals sound like whales; others liken them to the chirping of prairie dogs. What do you think? [audio] [

] [full story

Please give the audio a listen, it's awesome.

How can 'audio-frequency' signals travel through a vacuum? That said, there are myriad sources of electromagnetic 'noise' one could think of...

Article makes it clear this is electro-magnetic radiation between 0 and 10kHz that has been digitally sampled and converted to an audio signal.

Sounds like every radio I ever tuned into Radio Luxembourg - not sure if that was just the early pop music or meandering signals from near space!

You could almost picture Captain James T Kirk squinting in confusement as this is played on the Bridge of the USS Enterprise. Turning to Spock for answers, all he gets is.."Fascinating.!"

      New Planet Is Earth's Twin 200 Light Years Away   The planet, known as KOI-314c, is the same weight as Earth, but much larger and has a surface temperature of 104C.   Scientists have stumbled upon a planet considered Earth's 'twin' in another solar system 200 light years away.   Known as KOI-314c, the planet is the same weight as Earth, but is 60% larger.   The planet is also much hotter than Earth, with scientists estimating its surface temperatures to be around 104C - unsupportive of most life forms on Earth.   KOI-314c is suspected to have a thick gaseous atmosphere, making the planet only 30% denser than water.   However, despite a similar weight, astronomers said the planet is not considered "Earth-like".   "This planet might have the same mass as Earth, but it is certainly not Earth-like," said lead astronomer Dr David Kipping, from the Harvard-Smithsonian Centre for Astrophysics in the US.   He added: "It proves that there is no clear dividing line between rocky worlds like Earth and fluffier planets like water worlds or gas giants."   Scientists made the discovery by accident while searching for moons using the powerful Kepler space telescope.   "When we noticed this planet showed transit timing variations, the signature was clearly due to the other planet in the system and not a moon," said Dr Kipping.   "At first we were disappointed it wasn't a moon, but then we soon realised it was an extraordinary measurement."   Evidence of the new planet was presented at the annual meeting of the American Astronomical Society in Washington DC.   http://news.sky.com/story/1191102/new-planet-is-earths-twin-200-light-years-away   Might not be our earth but is close to it.Thats good news if something happens here.Just need to get used to hotter temps and other things...
