Astronomers now believe the Milky Way's "inevitable" collision with a neighboring galaxy is much less likely than originally ...

It turns out that looming collision between our Milky Way and Andromeda galaxies might not happen after all. Astronomers reported Monday that the probability of the two spiral galaxies colliding is ...

Using deep imaging from the James Webb Space Telescope, they observed a galaxy bearing a striking resemblance to our ...

Will the Milky Way and Andromeda galaxies collide in several billion years? The odds have changed with a new study using 100,000 supercomputer simulations. Credit: NASA's Goddard Space Flight Center ...

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 ...

From your place inside the Milky Way, you are living within a galaxy that keeps a detailed chemical diary. Every star holds clues about when it formed and what the galaxy was like at the time. Over ...

The Lambda Cold Dark Matter (LCDM) theory suggests that most galaxies are low-mass dwarf galaxies, many of which orbit larger galaxies like the Milky Way. More broadly, the LCDM represents our best ...

A high-resolution colour image showing the central galaxies NGC5713 and NGC5719 taken by the Hyper Suprime-Cam at the Subaru telescope in Hawaii. A cosmic dance could be the future of the Milky Way as ...

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 ...

Hypervelocity stars have, since the 1920s, been an important tool that allows astronomers to study the properties of the ...
