We know the most common facts about space and a few details about them. Most people know, Planets, Stars, and Galaxies, but there are other phenomenons in Space that are not so common. In this page we will find out more about those phenomenons!
Dwarf planets are pretty self-explanatory, they are planets which are small, like moon-sized small and they aren't exactly like the Planets in our Solar System. An example of dwarf planets would be our former planet, Pluto. To let you know how small Pluto is, it is smaller than Earth's moon, and most moons in our Solar System! You might be wondering why a planet is called a Dwarf Planet, it is because it is not the dominant Planet in its Orbital Path, and did not destroy it's neighboring obstacles.
This is how a Dwarf Planet is defined:

Supernovas are a powerful and illuminated explosion of a massive star. The star has to be at least 8 times greater than the mass of our Sun. A Supernova can be caused by something called the "Core Collapse," which is the death of a huge Star. They usaully occur during the last stage of a Star's life cycle Supernovas are often seen in galaxies, but we can't see them in the Milky Way, due to the dust blocking the view. Something bigger than Supernovas are Hypernovas, or sometimes known as collapsar. Scientists think a hypernova occurs when stars 30 times the mass of our Sun, collapse into a blackhole. The resulting explosion of a hypernova is typically 10 to 100 times more powerful than a supernova.

Black Holes are pretty much what the title suggests. They are massive holes in the universe that are invisible, because they are black, and blend in with their background. Most images with a black hole and it being bright, mean either it is swallowing a star, or the image is fake. Black Holes are formed when a huge star collapeses on itself. This collapse also results in a Supernova. If an object is within a certain range from a black hole, then, the object could be swallowed, if this happens, it can't escape. The black hole has a gravitational pull that is so intense that nothing, not even light, can escape it, once something is inside a certain region, called the event horizon.
