[00:00:00]Do you know the difference between a nebula and a galaxy? There are a lot of celestial bodies in space, but people don't know the difference between them.

[00:00:06]This is a main sequence star, a star in its early stages of life, basically a newborn star. This is a red giant. The outer layers of a red giant eventually blow up to become a nebula. Our sun will become a red giant in about 5 million years. This is a white dwarf. This is what remains when a red giant explodes.

[00:00:22]It's basically the core of a blown-up star. This is a red dwarf. They are the smallest and coolest type of stars. This is a galaxy, specifically our galaxy, the Milky Way. A galaxy consists of stars, planets, and vast clouds of gas and dust, which are basically nebulas.

[00:00:36]Now, this is a nebula. A nebula is a cloud of dust and gas in space. They are mostly formed by gas and dust that was thrown out from the explosion of dying stars. Nebulae are inside a galaxy. This is also a nebula, and this is a nebula, too.
