Rise in temperature and pressure as GPE (gravitational potential Energy) KE (kinetic energy)

Stars are formed from huge clouds of gas and dust called nebulae - Found mainly in spiral arms of Galaxy e.g. Orion’s nebula

Gas cloud begins to collapse and breaks up into protostars

Temperature at core reaches 15 million k. Fusion starts

Star reaches stable size

Outward pressure from radiation prevents any further collapse - Main sequence star is formed
