Black Hole Pulling In A Star
Facts and Information About Black Holes
You can’t see a black hole.
Our Milky Way likely has a black hole.
The first black hole was discovered by X-ray astronomy.
Although Black Holes were proposed in the 18th century, they were not discovered until 1964
Material spirals into a black hole through something called an accretion disk. This is a disk of gas, dust, stars and planets that begin to orbit the black hole.
Black holes cannot be captured by camera and they never die.
When near a black hole, time tends to slow down causing things to occur more slowly than it seems.
The nearest black hole to Earth is 1,600 light years away and it is one of the main things that astronomers think will destroy Earth.
A black hole has something called the “event horizon’ which is also called the point of no return. It is the edge of the black hole where the black hole starts to pull you in.
The Milky Way has a galaxy at its center that is 30,000 light years away and is 3 trillion times the size of our sun.
Black holes actually evaporate due to the fact or radiation because some radiation escapes a black hole as they are losing mass. This process will continue until there is no remains of the black hole.
Contrary to popular belief, black holes are actually spherical rather than a spiral downward shape.
Black holes are not always black. Since they emit radiation, some black holes have been know to glow in certain colors such as green and pink.
There are 3 different types of black holes known as spinning black holes, electrical black holes, and spinning electrical black holes. They are classified by the amount of energy they put out when the are distorting space.
Black holes produce sounds because they speed up objects and supercharges them causing a loud sound to occur.
Black holes created many of the fundamental elements that make up our world today and they also can spit things out rather than only suck.
The amount of stars in the universe is limited to the amount of black holes in it

How big can they be? - Nebulae can be huge in diameter stretching for hundreds of light. Nebulae are also very dense, but not quite as dense as any vacuum created on Earth.
Are there different types of Nebulae? - There are four types of Nebulae. The first type is called a Planetary Nebula which is a nebula with a glowing shell of ionized gas expanding and growing. Ionized gasses are remnants left from a red giant star and it is called a Planetary Nebula because it has a circular shape like a planet. The second type of Nebulae is called a H2 Region which is a region of space with ionized gasses. This area is large, dense and many stars are born within all the gas and dust H2 Regions tend to have no structure and are irregularly shaped. The third type of Nebulae is called a Supernova Remnant or a Crab Nebula. This type of Nebula results from when a star explodes into a supernova and the remnants of the explosion stay around. The Nebula expands, grows, and has an ovular shape like a crab. The fourth type of Nebulae is a called a Dark Nebula and this is an interstellar cloud that is so dense that not even light can be emitted from them.
