The boundary between stars and planets appears increasingly indistinct. Objects such as brown dwarfs, neither fully stars nor ...

Astronomers have caught what may be a rare cosmic catastrophe unfolding 11,000 light-years away. A seemingly ordinary sun-like star suddenly began flickering wildly, puzzling scientists until they ...

When worlds collide…suns act squirrely. Astronomers have witnessed a rare and violent cosmic crash between two planets, and ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered that aging stars in their so-called "red giant" phase are even more destructive to their orbiting planets than ...

Over 4 billion years ago, as planets were coalescing around the newborn Sun, our star may have gone on an epic road trip across the Milky Way along with thousands of stellar "twins." And we may owe ...

The traditional Habitable Zone (sometimes called the Goldilocks zone) is kind of like a campfire. If you sit too close, you ...

Is it a two-for-sun deal. Astronomers were blown away after discovering a bizarre exoplanet that orbits twin stars closer than any ever seen before in a binary star system, per a starry study ...

A seemingly regular, Sun-like star began acting really weird, flickering haphazardly as its light faded in and out. The cause of the star’s strange behavior may have been a cosmic catastrophe that’s ...

As of 2025, astronomers have identified at least 14 stars within 10 light-years of the Sun. After the Alpha Centauri system, the next closest is Barnard’s Star, a solo red dwarf roughly 6 light-years ...

Researchers in Switzerland have built an AI model to uncover potentially habitable worlds that are hiding from view. As detailed in a new study published in the journal Astronomy and & Astrophysics, ...

It’s an unprecedented snapshot of “time zero,” scientists reported Wednesday, when new worlds begin to gel. “We’ve captured a direct glimpse of the hot region where rocky planets like Earth are born ...
