A rapidly brightening burst of light called AT 2024wpp, or "the Whippet", is baffling astronomers. One explanation is that it ...

The conceptual architecture of black holes has undergone a radical transformation between 2024 and 2026, transitioning from the classical bottomless pits of general relativity to the intricate ...

CWISE J1249+36, a low-mass runaway star, is traveling at an extraordinary speed that could propel it out of the Milky Way.

Using the Chile-based ALMA telescope, the researchers examined the dynamics and chemistry of a central region.

New analysis suggests Webb’s little red dots are young black holes hidden in thick gas, with masses far smaller than first thought.

A NASA animation has sized the biggest black holes known to scientists, including one that has the mass of 66 billion Suns.

Some of the universe’s most extreme explosions leave behind almost no trace. The original explosion is unseen, but our ...
