"It's possible we will see the new data and confirm one theory over the other — or maybe we'll find nothing, in which case it ...

So how many stars are there? Given all of the above, astronomers estimate that the Milky Way contains around 100 billion stars, and there are at least 100 billion galaxies in the observable universe.

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 mystery of galaxies in the early Universe just got even weirder. A team of astronomers has identified a giant spiral galaxy so well-formed that it already has a stable galactic bar; a long, ...

At the heart of the Milky Way, a faint and widespread glow of gamma rays has puzzled astronomers for decades. The light could ...

For decades, astronomers have been vying to identify a source for a mysterious gamma-ray excess at the center of the Milky ...

Have you ever wondered how astronomers manage to map out the Milky Way when it's so incredibly vast? One of the most powerful tools is something called 21 cm radiation. Hydrogen, the most abundant ...

It's a fitting portrait of the facility that will soon transform our understanding of the dynamic universe by capturing ...

Scientists have built detailed Milky Way simulations under strange new physical laws to probe dark matter, revealing how different versions of the universe might behave and helping us get closer to ...

A two-year NASA mission is using research from a University of Arizona team to discover the origins of the Milky Way and the universe. SPHEREx, or Spectro-Photometer for the History of the Universe, ...
