Nebulae are collections of interstellar dust and gas which form stars. Our sun started as part of a nebula.

Nebulae come in different sizes and colours. Some are enormous and are almost as large as dwarf galaxies (Small-sized galaxies) and some are tiny and only stretch for about a few thousand kilometres long.

We will now go deeper into nebulae and explore!

Nebulae form when a star ends its life either in a planetary nebula, a supernova, or even a hypernova. These release gases which are required to make a nebula into space. Once enough of them are in place, they form a beautiful nebula.

This is a paradox that is sort of like the chicken or egg first question. But this time they ask you: Were stars born first or were nebula born fist? The answer is nebula. Gas is more likely to come out of nothing than an enormous object suddenly appearing right after the big bang. But we still don't have a logical explanation for that, so it remains a paradox.
