Hubble spies a very sparkly mini-galaxy

New images released by NASA’s Hubble Space Telescope are of the Pegasus Dwarf Spheroidal Galaxy, also known as Andromeda VI. The Pegasus Dwarf is located in the Andromeda Galaxy, also called Messier 31, which is the Milky Way’s closest neighbour at about 2.5 million light years away. As such, Andromeda is one of the few galaxies visible to the naked eye – best observed in November. The images were captured as part of a re-examination of the entire Andromeda system, meant to gather further information to answer longstanding questions related to dark matter, reionisation and the growth of galactic ecosystems across cosmic time.
