Triangulum Galaxy – Introduction
http://iddaasiteleri365.net/betbooda-arkadasini-davet-et-150-tl-kazan/ Triangulum galaxy is a Spiral Galaxy. It is known also as Messier 33 or M33, NGC 598 and Messier 101 (nick name).
http://silverspoonthaiandsushi.com/tag/indian/ Triangulum Galaxy discovered by an Italian astronomer Giovanni Battista Hodierna before 1654. But independently it discovered by Charles Messier in 25-26 August 1764 in night.
- It is the third largest galaxy in our local group after Milky Way Galaxy and Andromeda Galaxy.
- It is referred by Pinwheel Galaxy.
- This galaxy is located in Constellation Triangulum.
- It is approximately 60,000 light years across (almost half diameter of the milky way galaxy).
- This galaxy contains 40 billion stars.
- it has mass approximately 10 billion to 40 billion solar masses.
- Andromeda galaxy shines 8 to 9 times more than Triangulum galaxy.
- Astronomers and scientists detected a source of water maser emission in 2005. These two water masers were detect in the opposite side of the Triangulum galaxy.
- Triangulum galaxy is moving towards Andromeda galaxy.
- There is clumpy steam of hydrogen gas which is linking Andromeda galaxy with Triangulum galaxy.
- A black hole detected in the center of this galaxy in 2007 which contains 15.7 times mass of the sun. this black hole is known as M33 X-7 which is known largest stellar mass black hole.
- M33 linked with M31 by several stream of neutral hydrogen which suggest that there past interaction took place from 2 to 8 billion years ago. And it is estimated again in 2.5 billion years in future.
This galaxy has a own small satellite galaxy which known as Pisces Dwarf Galaxy.
NASA and European scientists recorded a fingerprint of mystery molecule in this galaxy . And that is known as Diffuse Interstellar Bands (DIBs). It is unsolved nearly 100 years. If this will be solve then we can understand and explain the formation of the planets, stars and life.
Sometimes this galaxy looks transparent like a water spot on window.
There is a nebula (a cloud of gas and dust) in the core of this galaxy which called HII region.
