What did the Webb telescope discover about exoplanet atmospheres?

The Webb telescope found that some exoplanets have atmospheres, just like Earth, but they're different and full of surprises!

Imagine you’re wearing a mask when you go to a party. That mask is like an atmosphere around a planet. The Webb telescope looked at faraway planets, called exoplanets, and saw what kind of "masks" they wear.

Like Looking at a Rainbow

The Webb telescope can see the light from these faraway planets as it passes through their atmospheres. It's like looking at a rainbow, each color tells you something about what’s in the air around the planet. Some exoplanets have clouds, some have gases we don’t see on Earth, and some even have molecules that make scientists go "Whoa!"

A Surprise Party

One of the biggest surprises was finding water vapor on a planet that’s not too hot, like a warm day at the park! That means it might be able to support life, just like Earth. It's like discovering someone brought cake to the party when you thought they only had juice boxes.

The Webb telescope is like a super-smart detective, solving mysteries from way across the galaxy.
