This revealed that not only is Andromeda XXXV a satellite galaxy, but it is also small enough to change theories of how galaxies evolve. "It was really surprising," Bell said. "It's the faintest thing ...

The Andromeda galaxy, our cosmic neighbor, is far more turbulent than previously thought. A new survey by the Hubble Space Telescope has mapped the chaotic history of Andromeda’s dwarf galaxy system, ...

A discovery made by a team led by researchers at the University of Michigan tugs at the seams of some key cosmic lessons we thought we had learned from our own galaxy.

"Everything scattered in the Andromeda system is very asymmetric and perturbed," Weisz, principal investigator of this Hubble program, said in the statement. "It does appear that something significant ...

A Swarm of Dwarf Galaxies Buzz Around Our Milky Way's Twin Imagine the Milky Way and Andromeda as two massive aircraft ...

Researchers led by astronomers at the University of Michigan have discovered the smallest and dimmest galaxy to date that's orbiting the Andromeda system, the Milky Way's nearest major galactic ...

"Everything scattered in the Andromeda system is very asymmetric and perturbed. It does appear that something significant happened not too long ago," Weisz said. "Our work has shown that low-mass ...

We cross 2.5 million light-years to reach the Andromeda system, consisting of 36 dwarf satellite galaxies orbiting the giant spindle-shaped Andromeda galaxy at image center. An ambitious survey by ...

"We do find that there is a lot of diversity that needs to be explained in the Andromeda satellite system," said Daniel Weisz of the University of California, Berkeley. "The way things come ...

Not only is Andromeda XXXV the dimmest and smallest known satellite galaxy in the Andromeda system, it's about 3 million light-years away, making it very hard to spot. The ellipse within the inset ...
