Search for Life

Complex organic molecules that could be the precursors to the building blocks of life as we know it have been discovered in a disk of gas and dust swirling around an infant star.

The search for life beyond the solar system is heating up. Though biosignatures around super-Earth K2-18b remain unconfirmed, the JWST has found the planet could be a water-rich ocean world.

Up to 200 worlds investigated by NASA's exoplanet-hunting TESS satellite could be bigger than predicted, a finding that could impact our search for alien life.

New research indicates that cellular "pockets" that are the first step toward protocells, the precursors of life, could form in the methane seas of Saturn's moon Titan.

The skepticism and debate around the question of "are we alone in the universe" makes the field of astrobiology more cautious

A walk in the desert and a curious discovery could have revealed that the secrets of alien life grow in the harshest conditions on Earth in the form of lichen.

The skepticism continues over recent claims of possible hints of alien life on exoplanet K2-18b.

There are creatures here on Earth that may give us clues about how to communicate with extraterrestrial intelligence — dolphins, which are famously social and smart.

Scientists have discovered 26 previously unknown bacterial species in the clean rooms that were used to prep NASA's Phoenix Mars lander for its 2007 launch.
