Transcript of Sagittarius A

The Centre of the Milky Way Sagittarius A Sagittarius A is near the edge of the Sagittarius constellation, which is where its name comes from. Where the Star Got its Name It is at and is the centre of the Milky Way galaxy. It can be seen as part of the Sagittarius constellation. Location and Position in the Sky It was most likely very high mass star which is why it turned into a black hole. It is also possible that it became a super massive black hole because multiple black holes accumulated into that spot to make it larger. Type of Star Sagittarius A's age is unknown because we cannot be completely sure it even exists and we have limited information on that area of the galaxy. Age of Star Sagittarius A is in the black hole stage of its life cycle and will stay there until it finally collapses and returns to the nebulae. Where the Star is in its Life Cycle In The Future Sagittarius A will stay a super massive black hole for up to billions of years and eventually return to the nebulae when our galaxy collapses. Evidence for Claims on its Life Cycle Our galaxy rotates around a central point which has to have a very large mass. Chances are that it is a super massive black hole as they could have enough mass to be the galaxy's centre. What the Star Will Leave Us Sagittarius A has and will leave us many elements which may have played a part in the formation of our solar system. With a supernova large enough to create a super massive black hole, it most likely caused fusion between many elements. How the Star Fits Into the Big History Story When the star or stars which formed Sagittarius A exploded in a supernova, it most likely caused a lot of fusion and since our galaxy is formed around it, those elements may have spread and caused the formation of other parts of the galaxy or even our solar system. Without Sagittarius A, our solar system or even galaxy might not have formed. The elements it created could have contributed to human life and it the force which keeps us in the Milky Way.
