Our search for exoplanets is focused on Milky Way stars. It's been successful, with more than 6,000 detected so far.

In 1995, a pair of scientists discovered a planet outside our solar system orbiting a solar-type star. Since that ...

A team of scientists is developing a "quantum-sensitive" device that could capture direct images of Earth-like exoplanets — something astronomers tend to consider so difficult it's nearly impossible.

What happens when a planet contains immense quantities of water but is far too hot for that water to remain liquid?

If any giant planets orbited Eta Cassiopeiae A within about 8 AU, astronomers could spot their telltale signature in the spectrum of light from the star. And since no planets at all can survive the ...

Exoplanets like HD 189733b, Tres-2b, and TOI-849b display extreme conditions from glass rain to near-total darkness, offering ...

Eta Cassiopeiae, a nearby double star system, may host stable Earth-sized planets. Its lack of giant exoplanets makes it ...

TESS launched atop a SpaceX Falcon 9 in 2018 to study exoplanets that transit their star from our perspective, meaning they ...

Scientists have detected the first direct evidence of a coronal mass ejection from a star beyond our Sun, specifically the M dwarf StKM1-1262. This ma ...

Researchers at Cornell University have developed the first-ever reflectance spectra — essentially a color-coded key — of the ...

"Asteroseismology with Roman is possible because we don't need to ask the telescope to do anything it wasn't already planning ...
