Researchers show how an alien civilization on TRAPPIST-1e could find us by detecting our pollution. They simulated Earth as seen from 40 light-years away.
In a new study, astronomers say that at least some of the 7 Earth-sized TRAPPIST-1 exoplanets could be habitable now, even if they didn't start out that way.
New findings from NASA's Webb Space Telescope show that rocky exoplanet TRAPPIST-1 c is not Venus-like as theorized and only has a very thin atmosphere at best.
NASA's Webb space telescope has found that TRAPPIST-1 b, the innermost planet in the TRAPPIST-1 system, is airless and too hot for life.
Researchers announced results from Webb's 1st glimpse of the TRAPPIST-1 exoplanet system, which contains 7 Earth-sized worlds, several potentially habitable.
A new study of the seven Earth-sized exoplanets around TRAPPIST-1 indicate that all 7 planets are extremely similar to each other in makeup, but potentially quite different from Earth.
The red dwarf star TRAPPIST-1 - about 40 light-years away - has 7 Earth-sized exoplanets orbiting it. A new study puts limits on how many of those worlds have hazy or cloudy atmospheres.
How habitable are the 7 Earth-sized exoplanets of the nearby star TRAPPIST-1? Updated climate models suggest some may be similar to Venus, but at least one world may have oceans like Earth.
All 7 of the TRAPPIST-1 planets are Earth-sized and terrestrial, making them an ideal focus of study for planet formation and potential habitability.
Terrestrial means more like Earth than Jupiter or Saturn. Water-rich means a potential for life. New insights about the 7 planets orbiting the nearby star TRAPPIST-1.
A new Hubble study suggests possible substantial water on the outer Earth-sized planets orbiting nearby dwarf star TRAPPIST-1.
Big discovery! NASA's Spitzer Space Telescope has revealed 7 Earth-sized planets orbiting a tiny star only 40 light-years away. Three of them are firmly in the habitable zone.
The newly discovered exoplanets orbiting this nearby star are likely to be bathed in high-energy ultraviolet radiation. What would life be like there? An expert explains.
The Webb Space Telescope probed eternal sunrises and sunsets on exoplanet WASP-39b. It found differences in the atmospheres.
NASA's Webb space telescope has revealed that exoplanet LHS 1140 b is a super-Earth ocean world. It may have an ocean on one side or a global ice-covered ocean.
Exoplanets are worlds orbiting distant stars. Watch a video with an astronomer who studies them. Learn the history of our knowledge of exoplanets, and more.
Astronomers have discovered a new Earth-sized exoplanet orbiting the ultracool dwarf star SPECULOOS-3. But any atmosphere it had is probably long gone.
What is orbital resonance? It's a precise dance between heavenly bodies when their orbits line up, causing them to have specific synchronicities.
A new study says that rocky habitable exoplanets likely have less carbon dioxide in their atmospheres as compared to similar planets in the same system.
