Andromeda, Hubble Space Telescope and dwarf galaxies

How did Andromeda's dwarf galaxies form? Hubble Telescope finds more questions than answers
"It was actually a total surprise to find the satellites in that configuration and we still don’t fully understand why they appear that way."
Hubble sees mini galaxies surrounding Andromeda are pretty wild
"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 galaxies in other ecosystems have followed different evolutionary paths than what we know from the Milky Way satellite galaxies."
Hubble provides bird's-eye view of Andromeda galaxy's ecosystem
Located 2.5 million light-years away, the majestic Andromeda galaxy appears to the naked eye as a faint, spindle-shaped object roughly the angular size of the full moon. What backyard observers don't see is a swarm of nearly three dozen small satellite galaxies circling the Andromeda galaxy,
NASA's Hubble reveals bird's-eye view of our neighbouring Andromeda galaxy and its mysterious satellites
NASA's Hubble Space Telescope reveals surprising details about Andromeda's satellite galaxies, offering fresh insights into the galaxy's evolution, structure, and turbulent history, including a possib

New dwarf galaxy discovered in the halo of Andromeda galaxy
An international team of astronomers reports the discovery of a new dwarf galaxy, which they have named Pegasus VII. The newfound galaxy, which lies about 2.4 million light years away, was identified in the Ultraviolet Near-Infrared Optical Northern Survey (UNIONS).
