Question

short note on nebula​

Answer 1

Explanation:

Nebulae are made of dust and gases—mostly hydrogen and helium. The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. ... Eventually, the clump of dust and gas gets so big that it collapses from its own gravity.

Requíred Answer :

• A Nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form.
