Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered that aging stars in their so-called ...

"Throwing a close companion into the mix could possibly wreak further havoc on the already complicated processes surrounding ...

A team of researchers has demonstrated a new way in which sub-Neptune-sized exoplanets could produce a great deal of water.

When astronomers search for planets that could host liquid water on their surface, they start by looking at a star's ...

The powerful coronal mass ejection would have likely destroyed the atmospheres of any potentially habitable planets nearby ...

Astronomers have discovered that aging stars may be devouring their closest giant planets as they swell into red giants. Using NASA’s TESS telescope to study nearly half a million stars, scientists ...

Using data from NASA’s TESS mission, scientists can estimate the size (radius) of potential planets orbiting distant stars. However, to verify that these objects are truly planets and not low-mass ...

Researchers analyzed nearly half a million nearby star systems to understand how giant planets fare as their stars expand into red giants.

Astronomers say they spotted signs of a giant explosion releasing from a star beyond our solar system, one powerful enough to ...

This illustration shows an exoplanet orbiting around two brown dwarfs –– objects bigger than gas-giant planets but too small to be proper stars. ESO/M. Kornmesser Astronomers have discovered a ...
