Andromeda XXXV is only about 20,000 times more massive than our Sun—very small, even for a satellite galaxy. For comparison, the Milky Way’s mass is about 1.5 trillion solar masses ...

The James Webb Space Telescope reveals turbulent environments found in Sagittarius C, a core part of our Milky Way galaxy.

But the satellites of the Milky Way and M31 show different evolutionary histories, and this new galaxy, dubbed Andromeda XXXV, is no exception. The question of why Milky Way satellites appear so ...

This task is somewhat less challenging around the closest major galaxy to the Milky Way, Andromeda. Other dwarf galaxies have been spotted around Andromeda before, but these have been large and ...

A bright star within our Milky Way galaxy photobombed a beautiful new image of a distant galaxy with "patchy" spiral arms.

All good things come to an end—even the Milky Way. Our home galaxy ... colliding with its neighbor Andromeda. However, a new analysis of a more distant galaxy is hinting at another dramatic ...

"A supercomputer simulation shows many galaxies merging over time. The parts of galaxies we can see are glowing stars forming from gas in their central parts. Visualizations like these inform ...

A century ago, Edwin Hubble revolutionized our understanding of the universe by proving that the Milky Way is just one of ...

The cluster, full of more than 2,500 newborn stars that blaze blue in the Hubble image, is in a galaxy with far fewer heavy ...

Astronomers have discovered Andromeda XXXV, the smallest and faintest known galaxy, located 3 million light-years away. It challenges existing models of galaxy formation, as similar small galaxies ...

Astronomers at the University of Michigan have discovered a new satellite of the Andromeda Galaxy (M31), the Milky Way’s closest major galactic neighbor, and it has broken the record for the ...
