The small rotorcraft made history, hovering above Jezero Crater, demonstrating that powered, controlled flight on another planet is possible.

Oxygen in the atmosphere may not be an entirely reliable 'biosignature,' but there are ways to distinguish false positives from signs of life

To confirm life on other planets, we need to detect far more molecules in their atmospheres than we currently do

A planet in an unlikely orbit around a double star 336 light-years away may offer a clue to a mystery much closer to home: a hypothesized, distant body in our solar system dubbed "Planet Nine."

New research suggest that glycine, and very likely other amino acids, form in dense interstellar clouds well before they transform into new stars and planets.

In a new video from the NASA Astrobiology Program, astrobiologists Dr. Jason Dworkin and Dr. Scott Sandford explain the importance of the OSIRIS-REx mission in the quest to understand the role that asteroids and other small bodies play in the origins of life on Earth.  OSIRIS-REx & the

New lab experiments re-create the environment of Europa and find that the icy moon shines, even on its nightside. The effect is more than just a cool visual.

NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) has confirmed, for the first time, water on the sunlit surface of the Moon.

Some exoplanets have a direct line of sight to observe Earth’s biological qualities from far, far away.

Venus may have had an Earth-like environment billions of years ago, with water and a thin atmosphere. Yet testing such theories is difficult without geological samples to examine.
