The distribution of elements seen in the samples of Ryugu brought back by Hayabusa 2 hints at a wet past.

NASA-supported scientists have provided new information about the behavior of organic molecules frozen in brine under conditions similar to the surface of Saturn’s moon Enceladus.

In the quest to address fundamental questions about the nature of the universe and the search for extraterrestrial life, space has been an important frontier for human exploration.

The possibility of advanced civilizations building giant structures to harness the energy of their stars is time-honored, with examples going back to the early 20th century.

New research introduces the concept of subglacial liquid water as a pivotal element in broadening the boundaries of the conventional habitable zone.

Samples from Bennu may provide insights into how water and organic molecules first reached Earth, a core research focus of the OSIRIS-REx mission.

Life on a faraway planet—if it's out there—might not look anything like life on Earth. But there are only so many chemical ingredients in the universe's pantry, and only so many ways to mix them.

New research based on Cassini data strengthens the idea that Enceladus has the chemicals necessary for life.

NASA-supported researchers have attempted to quantify the rate at which information is transmitted on Earth, both within the planet’s biosphere (all life on Earth) and the technosphere (human technology).
