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

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 ...

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

This video provides an educational look at various exoplanets discovered within our galaxy. It examines the scientific ...

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 ...

Like a toddler right before naptime, TRAPPIST-1 is a small yet moody star. This little star, which sits in the constellation Aquarius about 40 light-years from Earth, spits out bursts of energy known ...

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 ...

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 ...

Astronomers have long searched for life within a rather narrow ring around a star, the "habitable zone," where a planet should be neither too hot nor too cold for liquid water. A new study argues that ...

Scientists have uncovered a surprising way to study the harsh space weather around young M dwarf stars. Mysterious dips in starlight turned out to be massive rings of plasma swirling in the stars’ ...
