Search for Life

The historic James Webb Space Telescope has confirmed its first rocky exoplanet, 41 light-years from Earth.

Opals, which contain a lot of water, have been found on Mars. They might be an indicator of past life and possibly a source of water for astronauts in the future.

NASA's leading planet-hunting spacecraft has spotted its second planet that matches Earth's size and may be able to retain liquid water — and both worlds orbit the same star.

NASA's Perseverance rover is wrapping up its prime mission after 687 Earth days on the Red Planet.

NASA astrobiologist Heather Graham answers pressing questions about life on Mars.

Detecting life on the icy Saturn moon of Enceladus could be achieved without even landing, but it wouldn't be easy, scientists say.

From investigating UFOs over Earth to using the most powerful telescope ever devised to peer into the atmosphere of alien worlds, 2022 has been a banner year in the search for extraterrestrial life.

Scientists have proposed another use for the world's largest gravitational wave observatory: scanning for the ripples in space-time left in the wake of gargantuan alien spaceships.

A non-descript star, TRAPPIST-1, is host to seven Earth-size planets and the James Webb Space Telescope is giving astronomers a thrilling new view of these worlds.

New research shows that even smaller impacts can warm and soften enough ice on Jupiter's moon Europa to send material sinking into the underlying ocean.

NASA's Perseverance rover is set to cache its first Mars sample in the next few days, kicking off a roughly month-long process that will see the robot drop 10 tubes of Red Planet material.

Two planets found by NASA's retired Kepler Space Telescope may be made mostly of water, according to new research.

As part of the Breakthrough Listen project, the MeerKAT radio telescope will search a million nearby stars for signals from technology that could indicate intelligent extraterrestrial life.

New research solves the puzzle of how amino acids formed within space rocks that bombarded Earth during the violent early epoch of the solar system.

UFOs are making headlines again, but lost in the hype and ruckus is the question of when this all started and how we got to this point.

A new video shows how a team of NASA and European Space Agency spacecraft plan to relay Martian rock samples to Earth.

The aircraft-borne SOFIA telescope could not find signs of a compound possibly linked to biological activity during observations of Venus' atmosphere.

The James Webb Space Telescope has revealed an exoplanet's atmosphere in unprecedented detail, allowing scientists to understand the planet's past and test methods for detecting alien life.
