Science Life Cycle of a Star
Süžeeskeem Tekst
- OMG! That's a nebula over there! That is the beginning of a new star! Nebula are clouds of dust and gas, floating around in space.
- About 10 million years later, the nebula is turned into a protostar. A protostar is mass of gas that is one of the earliest formations of a star.
- Later, nuclear fusion occurs, creating a low mass main sequence star. Nuclear fusion is when particles smash together.
- This boi got big, red, and cold. This is a red giant, and this is a star in an intermediate phase with a low surface temperature and a red hue.
- The red giant eventually turns into this, a really sick looking nebula! This is a planetary nebula. It is ring shaped and is formed by the expanding shell of gas released by an aging star.
- When our little star here is living out its final days, it becomes a white dwarf, which is the result of the star losing all of its central nuclear fuel. Later, it will end its saga and become whats known as a "black dwarf. This is when the white dwarf cools down and no longer emits heat or light.
