NASA and U.S. Government policies address research and personal misconduct, and provide avenues for reporting potential violations.

Conspectus. A central question in origin-of-life research is how biological macromolecules and cellular structures arose from simple precursors under prebi

Following the Viking many of the inferences of biological metabolism have been replicated via abiotic mechanisms we now know are plausible on Mars’ surface.

Enzymatic metabolism emerged from metal-catalyzed, aqueous reactions of H2, CO2, NH3 and phosphite at a hydrothermal vent.

The Astrobiology Graduate Conference (AbGradCon) is an annual, student-led conference to highlight and promote the scientific research of early career astrobiologists.

NASA’s latest asteroid samples reveal that key ingredients for life likely arrived from space billions of years ago, hinting at the possibility of extraterrestrial life.

NASA and U.S. Government policies address research and personal misconduct, and provide avenues for reporting potential violations.

Terrestrial exoplanets are expected to host secondary, high-metallicity atmospheres derived from outgassing of volatiles
