Stars are born when gravity causes gas and dust clouds (nebulae) to collapse, forming dense clumps that spin faster and heat up until nuclear fusion ignites, converting hydrogen into helium and releasing light and heat; more massive stars burn brighter and shorter-lived, while smaller stars become long-lived steady suns.

How Were Stars Born? The Shocking Truth Scientists Just RevealedAjouté :
Stars start in [music] messy cloud parties and one collapse turns the lights on. Picture a giant [music] cold cloud of gas and dust in space, a nebula. Slowly, gravity pulls bits together, making [music] dense clumps.
As a clump gets heavier, it collapses faster and spins like a skater pulling in their arms. The center heats up, [music] pressure rises, and after millions of years, boom, nuclear fusion ignites. Hydrogen [music] atoms fuse into helium, releasing light and heat. A new star is born. Bigger clumps [music] make massive, short-lived fireworks.
Smaller ones become longived steady suns. So next time you look up, remember every [music] twinkle started as a quiet cloud that couldn't help but glow.
