Astronomers want to collect as much data as possible using as many systems as possible. Sometimes that requires coordination ...

Their research was guided by a prediction from the 1970s: if a star collapses directly into a black hole, it should briefly glow in infrared light as it sheds its outer layers and becomes wrapped in ...

The James Webb Space Telescope and the Chandra X-ray Observatory have captured the clearest image yet of a galaxy cluster in the making, seen when the universe was only one billion years old.

Initial analysis suggested the nucleus was approximately 13.7 kilometers wide (roughly city-sized); however, researchers believe this may have been an overestimate. It is likely a long-period comet ...

Astronomers using two of NASA’s most powerful space telescopes have discovered a massive cluster of galaxies forming much earlier in the universe than scientists thought possible. The finding suggests ...
