In Earth’s upper atmosphere, a fast-moving band of air called the jet stream blows with winds of more than 442 kph, but they ...

How would detecting methane help astronomers identify if exoplanets, or even exomoons, have life as we know it, or even as we ...

By tracing the corkscrew wobble of two stars as they move through the sky, the Gaia space mission has discovered one new ...

One of the largest exoplanets to be found orbiting a relatively low-mass star has been discovered, thanks to the way the planet's gravity drags its star around on its journey through space.

"The climate of this planet is extreme and nothing like that of Earth. The planet's dayside is so hot that elements typically ...

Thousands of exoplanets have been discovered, only a select few show promise. Here we look at some of the most habitable exoplanets ever discovered ranked through their similarity to Earth. The result ...

We have never directly detected volcanic activity outside our solar system, in part because current telescopes aren’t powerful enough to take images of exoplanets’ surfaces. We might be able ...

With an assist from the NEID spectrograph, a team of astronomers have confirmed the existence of exoplanet Gaia-4b—one of the ...

UC Irvine astronomers used a 3D global computer model to compare the climates of exoplanets in different stellar and orbital configurations. They found that a planet orbiting a white dwarf star would ...

Astronomers have officially confirmed the existence of HD 20794 d, a super-Earth located just 20 light-years away, with conditions that could make it one of the most promising exoplanets for life ...
