It is catalogued as Messier 33 or NGC ( New General Catalogue) 598. With the D 25 isophotal diameter of 18.74 kiloparsecs (61,100 light-years ), the Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Andromeda Galaxy and the Milky Way . The galaxy is the second-smallest spiral galaxy in the Local Group ...
Local Group. Local Group of galaxies, including the massive members Messier 31 (Andromeda Galaxy) and Milky Way, as well as other nearby galaxies. Distribution of the iron content (in logarithmic scale) in four neighbouring dwarf galaxies of the Milky Way. The Local Group is the galaxy group that includes the Milky Way, where Earth is located.

NGC 4038 was a barred spiral galaxy and NGC 4039 was a spiral galaxy. 900 million years ago, the Antennae began to approach one another, looking similar to NGC 2207 and IC 2163. 600 million years ago, the Antennae passed through each other, looking like the Mice Galaxies. 300 million years ago, the Antennae's stars began to be released from ...
SN 1885A (also S Andromedae) was a supernova in the Andromeda Galaxy, the only one seen in that galaxy so far by astronomers. It was the first supernova ever seen outside the Milky Way, [3] though it was not appreciated at the time how far away it was. It is also known as "Supernova 1885".
Andromeda IX (And 9) is a dwarf spheroidal satellite of the Andromeda Galaxy. It was discovered in 2004 by resolved stellar photometry from the Sloan Digital Sky Survey (SDSS), by Zucker et al. (2004). [2] At the time of its discovery, it was the galaxy with the lowest known surface brightness, Σ V ≃ 26.8mags arcsec −2 and the faintest ...
