The Andromeda galaxy, also known as Messier 31 (M31), is a glittering beacon in this image released on June 25, 2025, in tribute to the groundbreaking legacy of astronomer Dr. Vera Rubin, whose observations transformed our understanding of the universe.\u00a0In the 1960s, Rubin and her colleagues studied M31 and determined that there was some unseen matter in the galaxy that was affecting how the galaxy and its spiral arms rotated. This unknown material was named \u201cdark matter.\u201d<\/p>\n

M31 is the closest\u00a0spiral galaxy<\/a>\u00a0to the\u00a0Milky Way<\/a>\u00a0at a distance of about 2.5 million\u00a0light-years<\/a>. Astronomers use Andromeda to understand the structure and evolution of our own spiral, which is much harder to do since Earth is embedded inside the Milky Way.<\/p>\n
