Andromeda Galaxy(M31)
Discovery Discovered by Simon Marius in 1612. A Persian astronomer Abd al- Rahman al Sufi wrote a
line about the chained consolation in the year 964. People wrote of Simon Marius as the discoverer of the
galaxy without taking note of al Sufi’s notes.

The Andromeda Galaxy is 2.5 million light years from Earth.
The size of the Andromeda galaxy is 7.1 x 10^11 solar masses.
It is one of the brightest messier object.Spitzer space telescope revealed the Andromeda
galaxy has about 1 trillion stars.
Facts

Did you know?
That in the future that the Andromeda Galaxy and the Milky Way Galaxy are expected to collide in about 4.5 billon years!

Milky WayGalaxy
The Andromeda Galaxy is the furthest object you can see with the naked eye. In light years it is about 250 million light years away. That means the light we see in our sky left the Andromeda Galaxy 250 million years ago.
The Andromeda Constellation
This is where the Andromeda Galaxy was found!

Different views of the
Andromeda Galaxy!
The estimated mass of the Andromeda halo (including the dark matter) has value of approximately 1.23×1012 solar masses (or 1.2 trillion solar masses) next to 1.9×1012 solar masses Milky Way.
Comparing and contrasting
Andromeda galaxy and
Milky Way Galaxy
The Andromeda Galaxy appears to have more common stars than the Milky Way, and the estimated luminosity of M31 is 2.6×1010 L , is ☉about 25% more than that of our own galaxy.
This is the Andromeda Galaxy's local group.
(1 Million light years)
Stars M31 is known to have a dense and
compact star cluster at its very center.
There are about 460 clusters that are connected with the Andromeda galaxy.
The biggest of the clusters is identified as Mayall II or nicknamed Globular One.
Mayall 1
This was a stamp in Germany in 1999!
Andromeda was the daughter of Cepheus and Cassiopeia, the legendary (white) King and Queen of Ethiopia.
Greek Mythology
Cassiopeia Andromeda Cepheus
In 2010, a team of astronomers found out that the Andromeda galaxy was formed out of the collision of two smaller galaxies between 5 and 9 billion years ago!
