If life exists elsewhere, it might not be on worlds like Earth. Here are some of the more peculiar places scientists are ...

To support alien life, a planet doesn’t have to be exactly like Earth, but it does need a few key ingredients. First, it should orbit its star at the right distance, where temperatures allow liquid ...

Researchers are particularly interested in planets orbiting orange K-dwarf stars, which could support life for billions of ...

Astronomers have narrowed down the cosmic search for life, identifying fewer than 50 rocky planets among thousands of known exoplanets that may have the right conditions to support life. Using new ...

This summer, exoplanet science—the study of planets orbiting stars beyond our sun—took a big step forward. Reports of helium gas escaping from the atmosphere of LHS 1140b propelled this exoplanet from ...

A new study from researchers in Japan suggests that a better way to search for alien life might be to look for suspiciously similar planets that are close to each other. The idea is that if life has ...

It’s a dizzyingly busy time for scientists searching for life on distant planets. To date, astronomers have cataloged more ...

A new study proposes detecting life in space by spotting patterns across many planets instead of focusing on one at a time. If life spreads and changes planetary environments, it could leave behind ...

Scientists have built a computer model of Earth without life to help determine whether ...
