What are the mechanisms of star formation?

Clouds in space, called stellar nurseries, are full of gas and dust, just like clouds here on Earth. When these clouds get crowded and heavy, they start to collapse, creating new stars.

How the Collapse Works

Imagine you're in a big, fluffy pillow. If it gets squished too much, it starts to push back, that’s what happens with these space clouds. As the cloud collapses, parts of it begin spinning faster and faster, like ice skaters pulling their arms in.

When Things Get Hot and Bright

As the gas and dust keep getting squeezed together, they get hotter and brighter, just like when you rub your hands together quickly and feel warmth. Eventually, this hot, bright spot becomes a new star, shining brightly in the sky, ready to light up the universe for millions of years!
