The James Webb Space Telescope has upended expectations again, revealing a massive spiral galaxy in the universe’s infancy ...

New simulations reveal that the Milky Way’s odd split between two chemically distinct groups of stars isn’t a universal ...

New simulations of Milky Way-like galaxies reveal that the strange split between two chemically distinct groups of stars may ...

Star chemistry reveals two spiral arms and a faint bridge in the Milky Way, offering a clearer view of hidden structure in ...

From your place inside the Milky Way, you are living within a galaxy that keeps a detailed chemical diary. Every star holds ...

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, ...

The discovery reinforces established theories about space. There could be many more satellite galaxies orbiting the Milky Way than previously thought or observed, according to astronomers. As many as ...

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 James Webb Space Telescope has captured an image of a baby, Milky Way-like galaxy that formed more than 13 billion years ago. This "Firefly Sparkle" galaxy could reveal how our own galaxy evolved.

A cosmic train wreck may be looming in our future. The Andromeda galaxy, a near twin of our Milky Way, is barreling toward us. You can already see it coming if you know where to look—Andromeda’s great ...
