One of the main questions in exoplanet science concerns M dwarfs (red dwarfs) and the habitability of exoplanets that orbit ...

JWST observations of the ultra-hot super-Earth exoplanet TOI-561 b provide the strongest evidence to date for an atmosphere surrounding a rocky planet beyond our Solar System.

James Webb observations show TOI-561b, an ultra-hot rocky exoplanet, has a thick atmosphere that redistributes heat.

Astronomers have identified four exoplanets orbiting Barnard’s Star, a red dwarf star just 6 light-years away from Earth. No, really, this time it’s for real! We have to emphasize this because ...

Exoplanets come up a lot these days, usually in headlines about distant stars, strange atmospheres, or the possibility of ...

Astronomers from the University of Geneva, working with colleagues in Canada and the United States, have captured the ...

What can a rocky molten exoplanet with an atmosphere teach astronomers about planetary formation and evolution? This is what a recent study published in The Astrophysical Journal Letters hopes to ...

Kepler-186f is a rocky little world in the Goldilocks zone around its star. It's the fifth planet from its parent star, and yet it orbits at a distance comparable with Mercury's orbit around our sun.

"When the Earth's mantle melts, it produces basalts," said Esteban Gazel, professor of engineering. Basalt, a gray-black volcanic rock found throughout the solar system, are key recorders of geologic ...

Artistic illustration of the internal structure of a lava planet in a cold state, showing a day‑side magma ocean overlain by a mineral atmosphere. The arrows indicate the direction of heat transport ...

Astronomers have added two more exoplanets to a growing study aimed at finding out whether rocky worlds near small, faint stars might have air. The new pair brings the number of targets in the project ...
