The small footprint and dim light of white dwarfs may make excellent backdrops for studying planets with enough water to harbor life.

The ANDES instrument will be used to search for signs of life in exoplanets and look for the very first stars as well as measuring the acceleration of the universe’s expansion.

Scientists the University of Hawaiʻi at Mānoa discovered that certain sulfur-containing organic molecules can form naturally in space without the presence of life and were delivered to Earth by comets and asteroids.

As we discover more and more exoplanets—and the current total is in excess of 5,200—we continue to try to learn more about them. Astrobiologists busy themselves analyzing their atmospheres searching for anything that provides a sign of life.

Why is the warm gas-giant exoplanet WASP-107 b so puffy? Two independent teams of researchers have an answer.

As scientists broaden their understanding of the extreme conditions in which life can flourish here on Earth—and expand their notions of what extraterrestrial life might look like—the search for life on Mars continues.

Does life exist beyond Earth? Spacecraft observations suggest that Enceladus has all the chemical building blocks necessary for life.

This is the best evidence to date for the existence of any rocky planet atmosphere outside our solar system.

There’s something poetic about humanity’s attempt to detect other civilizations somewhere in the Milky Way’s expanse. There’s also something futile about it.

A research team discovered higher-than-usual amounts of manganese in lakebed rocks within Gale Crater on Mars, which indicates that the sediments were formed in a river, delta, or near the shoreline of an ancient lake.
