Hubble Finds Giant Halo Around the Andromeda Galaxy
NASA, ESA, and A. Feild

Astronomers have discovered a large halo around the Andromeda Galaxy, one of our galactic next-door neighbors. Using data from the Hubble Space Telescope, astronomers identified the halo by investigating how light filters through its gas, which the Hubble team described as "seeing the glow of a flashlight shining through a fog". The large halo is believed to house half the mass of the galaxy's stars.

Only 2.5 million light-years away, the Andromeda Galaxy is visible from Earth to the naked eye on moonless nights. It is the largest and most massive galaxy of the Local Group, which is also comprised of our Milky Way Galaxy and the neighboring Triangulum Galaxy, amongst others. It is estimated to contain one trillion stars.
