The halo of the Andromeda galaxy is even more massive than scientists expected, the Hubble Space Telescope reveals



Galactic halos are both more massive and more complex than scientists realized, according to new observations from Hubble Space Telescope.

The revered telescope looked at the neighboring galaxy Andromeda, using dozens of different quasars to map the galactic halo. Andromeda, more officially known as M31, is a spiral galaxy of approximately the same size as Milky Way a galaxy in which we live, with about 1 trillion stars. Cosmically, it is next door, only 2.5 million light-years away, which means that Hubble can study its halo with unprecedented detail.
