An "extra exceptional" Tatooine-like exoplanet, orbiting two suns, has been discovered. Astronomers say the "huge" new world ...

"We reported hints of methane, but the question is, 'is the methane attributable to molecules in the atmosphere of the planet ...

A new gas giant world discovered by citizen scientists using data from NASA's exoplanet-hunting spacecraft TESS is cool, literally and figuratively. This makes TOI-4465 b a rare case of a giant planet ...

We have a couple of techniques that allow us to infer the presence of an exoplanet based on its effects on the light coming from its host star. But there’s an alternative approach that sometimes works ...

Artist's view of exoplanet SPECULOOS-3 b orbiting its star. The planet is as big as the Earth, while its star is slightly larger than Jupiter, but much more massive. (NASA/JPL-Caltech via Courthouse ...

Some minerals in lava could suggest water is nearby. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. One way to find water worlds beyond our ...

Astronomers observing exoplanet GJ 3470 b saw evidence of water, carbon dioxide, methane and sulfur dioxide. Astronomers hope the discovery of this exoplanet's sulfurous atmosphere will advance our ...

Astronomers have discovered a relatively cool and small exoplanet orbiting a nearby star, with a “year” of several months. The find offers a rare opportunity to study planets and solar systems like ...

Exomoons represent a crucial missing puzzle piece in our efforts to understand extrasolar planetary systems. To address this deficiency, we here describe an exomoon survey of 70 cool, giant transiting ...

Astronomers have just discovered a new Earth-sized exoplanet around SPECULOOS-3, an 'ultracool dwarf' star as small as Jupiter, twice as cold as our Sun, and located 55 light-years from Earth. After ...

A radio signal has been detected, pointing to the possible existence of a magnetic field on YZ Ceti b, an exoplanet 12 ...

The sulfur-laden atmosphere discovered on gaseous exoplanet GJ 3470 b, show here in an illustration orbiting its star in the constellation Cancer, could help researchers figure out how it (and similar ...
