Clues about how galaxies like our Milky Way form and evolve and why their stars show surprising chemical patterns have been ...

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

The Milky Way is a self-gravitating system primarily focused on converting interstellar gas into new stars, with the rate of star formation directly related to gas density, consistent with the ...

Clues about how galaxies like our Milky Way form and evolve and why their stars show surprising chemical patterns have been ...

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

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

A Milky Way doppleganger discovered in the early universe suggests some key physical ingredient is missing from cosmological models. When you purchase through links on our site, we may earn an ...

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 ...

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 ...
