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

Scientists have identified three Earth-sized planets orbiting two stars in the TOI-2267 system. Remarkably, planets transit ...

There are no confirmed exomoons, moons orbiting distant exoplanets in other solar systems. There are a few candidates, but none have passed the threshold and been accepted as confirmed. But they must ...

Astronomers at the University of Arizona’s Steward Observatory, led by Kevin Wagner, have identified evidence for a potential ...

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 ...

The system, known as TOI-2267, is described as a compact binary - two stars locked in a tight orbit around one another, ...

The study suggests that planets closest to their stars, especially those that orbit their stars in just 12 days or less, are at a higher risk of being sent to their doom by their aging suns.

"This successful test marks a major step forward in the development of future satellite control systems." For the first time, ...

In a surprising twist to our understanding of exoplanetary systems, astronomers have uncovered three Earth-sized planets ...

Planetary retrograde is an apparent backward motion as seen from Earth, creating the illusion of planets moving in reverse ...
