hello guys :D White dwarfs are what low-mass stars leave behind after their death , and red giants are basically the last thing stars are before that. White dwarfs are often made mostly of carbon and oxygen, and are very massive , containing at least half of the star in an object as small as the size of the earth . A single teaspoon of a white dwarf would have approx. the mass of a car. They do h... » Continue Reading
hello! ^^ continuing with my previous entry about stars, I'll go into more detail about low-mass stars! Low-mass stars are typically red or yellow and can be as small as 0.1 solar masses or as massive as 9 solar masses. This is the process for the more massive, yellow stars: They start off like every other star - clouds of H and He collapse under their gravity, forming a protostar, and then a star... » Continue Reading
Hii The whole life of stars is just a war between gravity (centripetal force) and energy emitted from thermonuclear reactions in the core of the star (centrifugal force) - gravity always wins What's a thermonuclear reaction? A thermonuclear reaction happens in very high temperatures (in our Sun, this reaction happens at around 16 000 000K), and its the fusion of two atomic nuclei into a single, ... » Continue Reading
hey sigmas this is my first entry so hurray!! anyways Im probably gonna do a blog abt space and what I learned - feel free to add some information or correct me, I would really appreciate it :D the universe started out with the Big Bang around 13.7 billion years ago there is much more information about the Big Bang and what happened in milliseconds after it, but I'm gonna skip this because I don't... » Continue Reading
