Simple explanations
on topics regarding space.
Just like White Dwarfs are the evolutionary endpoint for a low mass to medium size star, black holes are one of the two possible fates of a massive star. A massive star is a star that which mass surpass 8M (solar masses). Black holes are, despite popular belief, not made up of highly compact matter. Black holes are in fact matter that no longer exist.
Did you know?
That White Dwarfs, in spite of their size, are one of the most dense forms of
mass in our discovered Universe? White dwarfs have a density of 1 x 109 kg/m3.
For reference, the density of earth is 5.4 x 103 kg/m3. That means that even a
tsp of matter from a white dwarf star would weigh multipe ton!
Not only humans, animals and plants have a life cycle, so does stars. When a star reaches its final stage of their cycle it can go one out of two paths. Which path the star takes depends on different factors, one of them being size. When a star has a mass that is larger than 8M (solar masses), it is a massive star. These stars become either black holes or neutron stars at the end of their cycle, whereas a star with less than 8M becomes a white dwarf.
A satellite is an object that orbits around a planet or a star. Per example, the earth is a satellite because it orbits around the sun. So is our moon since it orbits around the earth. When we think of the word ‘satellite’ we often associate it with a machine that is launched and floats around in space.

The higher the mass of an object is, the greater the gravity is. When the object reaches a certain amount of mass it gets so heavy that it bends the fabric of spacetime and distorts light rays.
