Exoplanet habitability depends on a whole host of factors, with liquid water at the top of the list. It also requires a stable atmosphere, the right chemistry, and possibly even things like plate ...

A gas giant planet beyond the solar that wobbles as it circles its star, hinting to astronomers that it is orbited by its own moon. To make this suspected discovery even more remarkable, if this moon ...

The team of astronomers behind the find suggested it could help us better understand planet and moon formation in our solar system and beyond the Milky Way. The team was able to make the first-ever ...

Many of the most interesting bodies in our Solar System aren’t planets, but the moons that orbit them. They have active volcanoes, hydrocarbon oceans, geysers, and moon-wide oceans buried under icy ...

Astronomers using the James Webb Space Telescope have captured breathtakingly detailed images of two giant exoplanets orbiting a distant sun-like star. These observations revealed sand-like silicate ...

An artist's illustration depicts the exoplanet LHS 3844b. (NASA/JPL-Caltech/R. Hurt (IPAC)) The James Webb Space Telescope (JWST) has revealed a dark, scorched world that may be similar to the Moon or ...

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 ...

The James Webb Space Telescope has detected water vapor and thick clouds on LTT 9779 b, an ultra-hot Neptune locked in a blistering 19-hour orbit. When you purchase through links on our site, we may ...

Using a new technique that partly relies on artificial intelligence, researchers spotted potentially more than 10,000 new ...

Nearly 700 light-years from Earth, morning clouds make way for a clear night on the exoplanet WASP-94A b. Scientists ...

Mars holds a special place in the solar system. It represents marginal habitability. This means it transitioned from warm and ...
