  1. Podcast A star is born Angela Park

  2. The beginning of Star Birth • Begin as just particles • Floating around in clouds of just and gas • Everything gets all crazy when there is a disturbance • All those particles start spinning around • A clump of particles, just even a small clump of particles, ends up having a gravitational pull on other clumps • Clumping together and forming bigger clumps

  3. Protostar • As more matter is pulled into the clump, its center is going to grow denser and it’s going • Clump grows into a small dense body and it’s called a protostar. • This protostar continues to draw in even more gas, and it gets even hotter. • When it gets hot enough, the hydrogen atoms begin to fuse, producing helium in an outflow of energy

  4. Nuclear fusion • Bang! nuclear fusion • However, the outward push of its fusion energy is still weaker than the inward pull of gravity • After millions of years, some of these struggling stars reach the tipping point. • Reach enough mass • Now the outward force is stronger than inward force.
