There are approximately 100 billion different solar systems in the Milky Way. Our dolor system is 25,000 light years away from the center of our galaxy. Our galaxy is so big we have only gone 19.5 kilometers from home. The farthest humans have gone is to the moon and back, which is only 238,900 miles away.

2. Our neighboring galaxy is Andromeda Andromeda is about 2.537 million light years away. You can see andromeda from the naked eye on Earth all year round because of its brightness. For us it look at it, it will look like a fuzzy star. But only with special equipment, you will be able to see the full beauty of Andromeda. Scientists believe that one day both of our galaxy will combine and create one big galaxy. We know …show more content…

It is almost like a massive, vigorous vacuum making it the second to largest black hole astronomers have ever seen. Two million years ago, the black hole was 100 times more powerful than it is today. Scientist are confused why the black hole is weakening because it's suppose to be the opposite. Sagittarius A is about 26,000 light years away from Earth and it is 100 more massive than the

Black Holes Argumentative Essay

677 Words | 3 Pages

Black holes are areas in which huge amounts of mass are compressed together, creating a gravitational field so strong that when it crosses the black hole, not even light can escape. They are the final stage for stars 10-15 times as massive as our Sun, because after they explode into a supernova, the gravity causes them to collapse into themselves. They shrink and compress mass until the former star’s volume is at 0. When this happens, they become infinitely dense and the star’s own light becomes trapped inside. The black holes can only pull in objects of similar or lesser mass, since their gravitational pull is only as strong as their mass.
