[00:00:00]How do scientists find [music] exoplanets?

[00:00:03]If you can't see most exoplanets, how do we actually find them?

[00:00:08]Well, they don't look for the planet, [music] they look for what it does.

[00:00:12]When a planet passes in front of its star, the star's light dims slightly.

[00:00:18]That tiny dip, that's a clue.

[00:00:21]Other times, [music] a planet's gravity makes its star wobble back and forth.

[00:00:26]That's another signal.

[00:00:28]So, no direct image just means patterns in light and motion.

[00:00:33]That's how we've discovered thousands of worlds light-years [music] away. We don't see them, but we detect their fingerprints.
