andromeda galaxy

The Andromeda Galaxy, also known as Messier 31, M31, or NGC 224, is a barred spiral galaxy, located approximately 2.5 million light-years (770 kiloparsecs) from Earth: the nearest major galaxy to the Milky Way.

This spiral galaxy, like the Milky Way, contains a concentrated bulge of matter in the middle, surrounded by a disk of gas, dust, and stars and an immense halo.

The virial mass of the Andromeda Galaxy is of the same order of magnitude as that of the Milky Way, at 1 trillion solar masses. The mass of either galaxy is difficult to estimate with any accuracy, but it was long thought that the Andromeda Galaxy is more massive than the Milky Way by a margin of some 25% to 50%.

The Andromeda galaxy is the brightest galaxy you can see. The Andromeda Galaxy's mass is estimated to be around 1.76 times that of the Milky Way Galaxy.

How to see the Andromeda Galaxy

The Andromeda Galaxy is the most distant thing you can see with your eye alone and can be seen in our sky for much of every year. Every August, it’s ascending in the sky during the evening hours. To the naked eye, it looks like a fuzzy patch.

With larger telescopes, it is possible to see a lot of globular clusters and HII regions in the galaxy. In the southwestern part of Andromeda Galaxy lies NGC 206, a stellar association that is visible in medium to large telescopes.

An amateur telescope can reveal Andromeda's disk, some of its brightest globular clusters, dark dust lanes and the large star cloud NGC 206.

Andromeda Galaxy can be seen at its best view using our telescopes located in Spain.
