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.
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.
Say if Mars had intelligent beings able to talk to us at the same time as we talked to them -- how would that have changed our history?
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.
A series of laboratory tests show that some terrestrial bacteria would adapt well to the salty and sulfate-rich ocean believed to exist beneath the hard icy shell of Europa.
It's a virtual certainty that comets have delivered the building blocks of life to Europa's hidden ocean, according to a new study.
Although scientists have long considered oxygen a sign that life exists on an alien planet, new research suggests the element could be produced without it.
Red dwarf stars may be able to support habitable exoplanets after all -- through complex tidal interactions between star and planet, global magnetic fields could evolve, protecting hypothetical life forms from the red dwarfs' ferocious nature.
