The sun's returning coronal hole could stir up geomagnetic storms and dazzling auroras under clear, dark skies this weekend.

In the 1980s, Finnish astronomer Aimo Sillanpää noticed its repeating light pattern and proposed the idea of two black holes. Since then, researchers around the world have tracked the system, trying ...

Observations by a system of radio telescopes have offered the first visual evidence for the existence of black hole pairs.

Scientists have for the first time ever succeeded in getting some data on a newborn black hole that was sent hurtling off into space after two larger ones collided together and "birthed" it. The ...

Two black holes collided 1.3 billion light years from Earth, creating a 'ringing,' which in turn allowed astrophysicists to test some theories. And it turns out, they were all correct.

A proposed interstellar mission envisions sending a gram-scale nanocraft, propelled by a laser-driven lightsail to a nearby black hole, achieving approximately one-third the speed of light. Upon ...

When two massive black holes slammed into each other earlier this year, astronomers were able to observe it in the clearest ...

A strange chirp detected by LIGO in 2019 has some scientists searching for answers beyond a simple black hole merger.

"It's an elegant answer, really, because we thought it was a tiny galaxy full of many separate cold stars, but it's actually, ...
