The chemicals necessary for the formation of life have been detected in lab-grown comet ice -- a discovery that could have huge implications for discovering how life as we know it was spawned.
California-based SETI Institute plans to expand a hunt for radio signals broadcast by extraterrestrial civilizations by scanning red dwarf stars, which are older and smaller than stars like the sun.
Should humankind establish a presence throughout the solar system, future rock climbers and mountaineers might want to put Titan on their list of exploration destinations.
The identification of core genes needed for life may not only spill secrets of how biology got its start on Earth, but also shed light on the hunt for life beyond the planet.
Microscopic dust grains extracted from meteorites that landed on Earth had ancient and explosive origins, scientists have discovered.
In the search for Earth-like worlds beyond the solar system, Kepler-438b seems to have it all. Alas, its angry star is a poor host for any potential lifeforms.
A pale blue dot may not be the only hint of life beyond the solar system. New research suggests astronomers pay attention to pale orange worlds as well, since they may resemble what Earth looked like earlier in its history.
