1 day ago · This encompasses about 50 major Local Group galaxies, and some that are members of neighboring galaxy groups, the M81 Group and the Centaurus A/M83 Group, and some that are currently not in any defined galaxy group. The list aims to reflect current knowledge: not all galaxies within the 3.8 Mpc radius have been discovered.
4 days ago · The Andromeda Galaxy has a diameter of about 46.56 kpc (152,000 ly), making it the largest member of the Local Group of galaxies in terms of extension. [13] The Milky Way and Andromeda galaxies are expected to collide with each other in around 4–5 billion years, [14] merging to potentially form a giant elliptical galaxy [15] or a large ...

May 18, 2024 · Our galaxy is part of a collection of galaxies called the Local Group, which includes the Milky Way; the Andromeda galaxy; a smaller spiral galaxy called Triangulum; and several dwarf...
3 days ago · We discuss the dipole and the quadrupole rate for the Local Group of Galaxies and the implementations for Hubble diagram correction and galaxy groups viralization. With these definitions, we indicate the surfaces showing the interplay between the local expansion vs the local Newtonian attraction for galaxy groups in the local Universe.
May 1, 2024 · Odd radio circles are glowing around some galaxies. Now we know why But in the 1970s, astrophysicists noticed that something was off about our galactic neighborhood, or Local Group.
