The EHT captured a surprising polarization reversal around M87*, pointing to rapidly changing magnetic fields near the black ...

The historic first image of the Messier 87 (M87) supermassive black hole, captured using the Event Horizon Telescope, has ...

The Event Horizon Telescope only recently gave us the first images of the environment immediately surrounding a black hole.

Astronomers watched how the light brightened and dimmed near the event horizon of the Milky Way's supermassive black hole, ...

Learn more about the images advanced telescopes could take of black holes and how they could back up Einstein’s general ...

Researchers are using black hole “shadow” images to test whether Einstein’s relativity remains unshakable. With next-generation telescopes, they hope to spot telltale signs of alternative physics ...

"The key result is that while many alternatives look very similar to the 'standard' black hole at today's image quality, the ...

Physicists have taken a new approach to whether all black holes conform to Einstein’s theory of general relativity or if ...

Supermassive black holes have some of the most voracious appetites in the universe, so astronomers at the University of Arizona and elsewhere can be forgiven for staring at one of them while it eats.

Each site in the telescope received four of these data recording units; at the end of the observations, they were shipped to one of two data processing centers—in total, a half a tonne of hard drives ...
