How do scientists search for and confirm the existence of exoplanets?

Scientists look for exoplanets, which are planets outside our solar system, like looking for new friends who live far away from us.

Imagine you're in a big room full of people talking. You can't see them, but you can hear their voices. If one person starts to whisper softly, you might notice they’re closer than the others. Scientists use this idea, they listen to how light changes when a planet passes in front of its star.

When a planet moves between its star and us, it blocks some of the light, like a curtain slightly covering a lamp. This is called the transit method. Scientists watch for these small dips in light, they know something is passing by!

Once scientists think they see a planet, they check again and again to be sure. Sometimes they use other tricks, like watching how the star wobbles, it's like when you push someone on a swing and you feel a little pull back.

So, by using these clever methods, scientists can find exoplanets and know that they're really there, not just imagination or chance!
