Protostar Formation 🌌 Birth of a Star Inside a Nebula

Explaining The Universe on Instagram: "Stars form inside giant clouds of gas and dust called nebulae, where gravity slowly pulls material together. As the gas condenses, the core of the collapsing cloud heats up, forming a dense, spinning sphere known as a protostar. Over time, as more matter falls inward, the temperature and pressure in the core rise until they become high enough for nuclear fusion to begin—hydrogen atoms fusing into helium. • #explore #reels #viral #universe #explaining #space
