Hubble provides bird's-eye view of Andromeda galaxy's ecosystem

Summary by Phys.org

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, like bees around a hive.

You won’t believe this stunning Andromeda galaxy photo was taken from someone’s backyard

For decades, capturing detailed images of galaxies beyond the Milky Way has felt like the exclusive domain of high-powered space telescopes like Hubble and the James Webb. But one backyard astrophotographer has shattered that notion with a stunning photo of the Andromeda Galaxy, revealing individual stars and swirling cosmic dust in breathtaking detail. Andrew McCarthy has made quite the name for himself over the past few years, revealing detail…

Hubble sees mini galaxies surrounding Andromeda are pretty wild

Surrounding the Andromeda galaxy, three dozen tiny galaxies aren't behaving the way scientists expected. NASA's Hubble Space Telescope has trained on Andromeda for a deep dive into how its orbiting satellite galaxies formed and changed over time. What they found revealed a population of dwarf galaxies that are quite unlike the ones circling the Milky Way. Some 2.5 million light-years away, these space neighborhoods formed the bulk of their stars…

NASA's Hubble Provides Bird's-Eye View of Andromeda Galaxy's Ecosystem

Hubble is studying a swarm of 36 dwarf galaxies that orbit our neighboring Andromeda Galaxy. The dwarf galaxies are evidence that Andromeda has had a more dynamic history than our Milky Way galaxy.

Andromeda's Dwarf Galaxies Reveal Unique Star Formation Histories

The Andromeda Galaxy, our nearest large neighbour, has 36 identified dwarf galaxies. The Hubble telescope took images of Andromeda and its dwarfs during more than 1,000 orbits, creating a precise 3D map. Astronomers used these observations to reconstruct the dwarf galaxies’ star formation histories. The results show that their environment plays a critical role in their star formation and their quenching. When galaxies are quenched, they no longe…
