The search for Earth 2.0 has begun in earnest. But there's a huge variety of exoplanets out there, so narrowing down the search to focus valuable telescope time on only the best candidates is critical ...

Data analyzed by UChicago scientists reveals exoplanet Kua’kua is dark and rocky, offering clues to search for habitable ...

Provided they host thick, hydrogen-dominated atmospheres, moons orbiting free-floating exoplanets could retain much of the heat generated deep within their interiors by tidal forces. Led by David ...

Frequent flares from the nearby star TRAPPIST-1 could offer new clues in the search for habitable planets beyond Earth. TRAPPIST-1 is an ultracool red dwarf, located about 40 light-years away in the ...

Astronomers might be close to confirming the presence of an Earth-like atmosphere on an exoplanet for the first time, if more detailed analyses verify preliminary observations from the James Webb ...

Space telescopes are revolutionizing exoplanet discovery, allowing astronomers to detect Earth-like worlds orbiting distant stars. By observing subtle dimming of starlight, measuring gravitational ...

How much water do habitable exoplanets need for life as we know it to exist? This is what a recent study published in The Planetary Science Journal hopes to address as a team of scientists ...

Between 2018 and 2019, NASA’s Transiting Exoplanet Survey Satellite photographed more than 56 million stars during its first ...

When astronomers search for planets that could host liquid water on their surface, they start by looking at a star’s habitable zone. Water is a key ingredient for life, and on a planet too close to ...

The Hubble Space Telescope celebrates 36 years of incredible discoveries, stunning imagery, and a lasting impact on astronomy ...
