A group calling itself Lone Signal plans to use old school space program technology to send messages from people around the world into space.
One of the most prolific tools in the search for potential life beyond Earth is in critical condition.
NASA's Kepler Mission has already discovered over 100 planets, some of them habitable. But how exactly does it work?
NASA’s Kepler mission has discovered two new potentially habitable planets in a solar system a lot like ours.
A new list of Earth-like exoplanets has been announced, and we're bringing you the top nine.
The SETI Institute pointed a big radio telescope at some recently discovered exoplanets in habitable zones, looking for telltale signs of alien life.
After an update to atmospheric absorption parameters tweaks the habitable zone around stars, Earth turns out to be a lot less habitable than it seems.
So far, our search for Martians and other extraterrestrial forms of life hasn't quite panned out, but that doesn't stop us from continuing to look. Now astronomers at the University of Hertfordshire in England have discovered a new system of planets, which in many ways are remarkably similar to our own neighborhood and may even support life.
Well, this is pretty damn exciting: astronomers have confirmed the detection of a planet just 1.13 times the size of Earth orbiting around Alpha Centauri B, which is part of the closest star system to Earth. At just 4.3 light-years away, it's potentially reachable in just a few decades with near-term technology, and now we've got a place to land. Er, sort of.
55 Cancri e was first identified back in 2004, but at the time scientists thought that it was covered in water and rocks, much like the Earth. We now know that's probably not true and, what's more, the most interesting find regarding 55 Cancri e could be under the surface.
