What is cosmic dust? | National Museums Liverpool?

Cosmic dust is like tiny specks of sand floating around in space, super small, and made from things that are scattered all over the universe.

Imagine you're playing with a box full of different kinds of sand: some glittery, some dark, some sparkly. That's kind of what cosmic dust looks like, but instead of being in a toy box, it’s floating between stars, planets, and even comets.

Sometimes, when you look up at the sky on a clear night, you can see stars twinkling. But sometimes, there are hazy areas that look kind of like smog, those are made from cosmic dust. It’s so tiny, it's hard to see with just our eyes, but scientists can catch it in special containers that fly through space or fall down to Earth as part of a meteor.

Cosmic dust has bits of things like carbon, silicon, and even iron, the same kinds of materials you find in rocks and soil. It's like the universe is making its own kind of sand from faraway places, and some of it ends up on our planet!
