Transcript of Andromeda Galaxy

http://en.wikipedia.org/wiki/Andromeda_Galaxy What is Andromeda? History What if Andromeda and our Milky way collided? Watch this video to find out! ~Andromeda is a spiral galaxy more than 2.5 million light years away. Being that far away, Andromeda is still the closest galaxy to us. - In the video, the galaxies circle each other due the large amounts of gravity present in their centers. Nucleus - Andromeda galaxy is 9 billion years old. Quite old for our 13.7 billion year old universe. - It was originaly named after a Greek mythological Princess - In the center of Andromeda, there is a compact cluster of stars called a bulge http://www.space.com/15590-andromeda-galaxy-m31.html - In 964, a Persian astronomer named Abd al-Rahman al-Sufi saw the galaxy and named it "small cloud" in his Book of Fixed Stars this was the first known report of Andromeda. - Later on in 1612, Simon Mariuo researched this topic further and with more detail. History Cont'd ~It is larger than our Milky Way
~ Andromeda, from edge to edge, measures 220,000 light years while the Milky Way measures about 120,000 light years. - The bulge contains two major concentrations of stars, P1 and P2. - P2 consists of a large black hole. The Milky Way also contains a black hole in the center. - Every second, Andromeda Galaxy moves 100-140 km towards us! - In the year 1764, Charles Messier, a scientist, rediscovered
Andromeda and named it Messier 31 or M31 - Recently it was discovered that there is a rare mini quasar sucking in matter in Andromeda http://www.space.com/18871-microquasar-black-hole-andromeda.html Quasars are super massive black holes that release a lot of light as they destroy stars and suck in matter. Definition Stars - M31 contains over one trillion stars! While the Milky Way only contains 300 billion. - Acording to a team of astronomers, Andromeda formed when two smaller galaxies clashed approximately 5 to 9 billion years ago. - Of course we are not sure
if there are aliens or not.
However, for a galaxy with
billions of planets, it is
highly likely that there is
at least one planet where there is life (maybe as small as bacteria) or where life is possible. Google Images
