A new exoplanet model screens rocky worlds by their ability to retain atmospheres over geologic timescales, helping narrow ...

Scientists search for exoplanets and signs of life in space because understanding whether life exists beyond Earth is one of the most important goals in modern science. In space exploration, ...

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 ...

Officers from the German Air Force check out the Firefly Aerospace's Blue Ghost that is on display at the 41st Space Foundation Space Symposium at the Broadmoor Hotel on Monday, April 13, 2026. The ...

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 ...

Any planet at the right distance from its star to allow liquid surface water was considered to be in the habitable zone. But now, as astronomers find more and more exoplanets, the definition of ...

Moons orbiting rogue planets, worlds flung from their parent star systems into the cold of interstellar space, could maintain liquid water on their surfaces for billions of years if wrapped in a dense ...

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’ ...

The definition of a habitable zone was necessarily simple in the beginning. Any planet at the right distance from its star to allow liquid surface water was considered to be in the habitable zone. But ...
