4. How do new stars form inside Jack B. Newton?Gravity pulls parts of the cloud together, and when they become dense enough, they collapse and start nuclear fusion, becoming new stars.

Emission Nebula: A celestial cloud of ionized gas that emits its own visible light, typically energized by nearby hot stars.
H II Region: A region of interstellar atomic hydrogen that has been ionized, often associated with star formation.
Stellar Nursery: A region in space where conditions are favorable for the birth of new stars from collapsing clouds of gas and dust.
Open Cluster: A group of up to a few thousand stars that were formed from the same giant molecular cloud and are still loosely gravitationally bound.
