What if the Milky Way’s central “black hole” isn’t a black hole at all? A new model proposes that an ultra-dense dark matter core could mimic its gravitational pull.

Recent observations suggest that 'runaway' black holes are tumbling through the cosmos. Building on decades of theory, the discovery adds a remarkable new chapter to the story of the universe.

This week in science: Mysterious molecules on Mars are tricky to explain without life; a compound that cuts cholesterol as a ...

A massive star 2.5 million light-years away simply vanished — and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in a ...

UNRWA chief warns axing agency would create Iraq-style vacuum as US weighs future role amid funding freeze and Hamas ...

The den was under an abandoned house near Hunters. Neighbors had reported seeing a black bear walking around the property, gathering grass and other den-making material. They were alarmed.

Using archival data from NASA’s NEOWISE mission along with data from other space and ground-based observatories, astronomers identified the clearest observational record yet of a massive star fading ...

The Los Angeles Unified School District is weighing mass layoffs as it faces a deficit of nearly $200 million – driven by ...
