…asteroid Bennu has provided groundbreaking insights into the chemistry that may have set the stage for life in the early solar system. Researchers analyzing samples from NASA’s OSIRIS-REx mission discovered…
Nitrogen was not a limiting factor for early life on Earth, as microbes stabilized nitrogen fixation and hydrothermal vents supplied ammonium, which may also support life on other planets. A…
