What is panspermia?

Spores travel through space and land on other planets, that’s panspermia.

Imagine you're playing with your favorite toy car. You push it across the floor, and it rolls all the way to the other side of the room. Now imagine instead of a toy car, it was something tiny, like a seed or a microscopic creature, and instead of a room, it was space. That’s what panspermia is like: tiny life forms or parts of life travel through space on rocks or dust, and then they land on another planet, like Earth.

When a big rock from another planet crashes into Earth, sometimes it brings along tiny passengers, like seeds or microbes. These tiny travelers might be able to survive the long trip in space, just like you can survive a short ride in a car. Once they reach Earth, they could start growing and multiplying, becoming new life.

Scientists think panspermia helps explain how life started on Earth, maybe it came from another planet or even another star system! It’s like getting a surprise gift from the universe, wrapped in rock and space dust. Spores travel through space and land on other planets, that’s panspermia.
