Astronomers have witnessed something that no one believed possible: a black hole ripping apart a star not at the center of a galaxy, but far from it. More amazingly, the event’s radio waves pulsed and ...

Astronomers had long suspected that certain quasars—those brilliant, otherworldly light sources fueled by supermassive black holes—could harbor two black holes rather than one. That theory, long ...

When two black holes meet, they are drawn to one another by way of their enormous gravity, initiating a powerful orbital dance, spiraling closer together over time, until one subsumes the other and ...

The James Webb Space Telescope (JWST) has once again captured the attention of the scientific community with its latest discovery. On October 15, 2025, the telescope detected something described as ...

An international team of astronomers has discovered the first tidal disruption event (TDE) producing bright radio emission outside the center of a galaxy. The findings are published in The ...

After decades of searching, astronomers have imaged two supermassive black holes in orbit around each other at the heart of quasar OJ287. Astronomers have captured a radio image showing two black ...

When galaxies collide, it's not a gentle affair, but it does take millions of years. Over this time, the two massive star systems slowly merge together, their gravitational pull drawing them closer.

This summer, astronomers detected a gamma ray burst (GRB) so powerful that they’re still struggling to explain what caused it. These cosmic explosions are typically produced by stars dying in a ...

For 50 years, astronomers have been searching for evidence of winds emanating from the black hole Sagittarius A*. Now, they finally think they have an answer. Reading time 3 minutes Every large galaxy ...

Finnish scientists have shot two black holes orbiting each other, offering the first ever definitive proof that these intergalactic voids come in pairs, per a study published October 9 in the ...

A consensus is emerging that the dots, sometimes called rubies, are an entirely new type of object in the Universe. When the James Webb Space Telescope (JWST) looked back in time to observe the ...
