New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite galaxies—up to 100 more than we currently know. These elusive "orphan" galaxies have ...

The solution to a persistent astronomical question that has puzzled scientists for half a century has emerged not from direct observation, but from the computing power of sophisticated computer ...

JWST observations show that early galaxies were chaotic, gas-filled systems rather than stable disks. Researchers from Cambridge studied over 250 galaxies and found most were turbulent, still forming ...

Astronomers have discovered a vast, dense cluster of massive galaxies just 1 billion years after the Big Bang, each forming stars at an intense rate from collapsing clouds of dust. Reported in ...

The first images from a new telescope in Chile were released this week, featuring extraordinarily detailed scenes from deep space. And more are expected to follow the debut series from the ...
