Description

The Andromeda Galaxy, also known as Messier 31, M31, or NGC 224  is a barred spiral galaxy approximately 2.5 million light-years from Earth and the nearest large galaxy to the Milky Way. The number of stars contained in the Andromeda Galaxy is estimated at one trillion , or roughly twice the number estimated for the Milky Way.

The Milky Way and Andromeda galaxies are expected to collide in around 4-5 billion years,merging to form a giant elliptical galaxy or a large lenticular galaxy. With an apparent magnitude of 3.4, the Andromeda Galaxy is among the brightest of the Messier objects, making it visible to the naked eye from Earth on moonless nights,even when viewed from areas with moderate light pollution.
