What’s inside the Andromeda Galaxy?
The Andromeda Galaxy, also known as Messier 31 or M31, is a spiral galaxy located approximately 2.537 million light-years from Earth. It is the closest major galaxy to the Milky Way and is visible in the night sky with the naked eye.
The Andromeda Galaxy is similar to the Milky Way and is believed to contain a central bulge of older stars, a disk of younger stars and gas, and a halo of diffuse stars and dark matter.
The galaxy is home to billions of stars, as well as planets, dust and gas. It is also believed to contain a central supermassive black hole with a mass of about 70 million times that of the Sun.
In addition to stars and planets, the Andromeda Galaxy is home to a variety of other celestial objects, including nebulae, clusters, and supernova remnants.
It is also believed to contain a significant amount of dark matter, which is a mysterious and largely unknown form of matter that does not emit, absorb, or reflect light and is believed to make up a significant portion of the universe’s mass.
