Imagine a world far, far away. It's a planet, just like Earth, but it orbits a different star. These planets are called exoplanets. Scientists have found thousands of them, some big and gassy like Jupiter, others small and rocky like Earth. Some might even have water, just like our planet. It's exciting to think that there might be other planets with life on them. Maybe there are aliens or other creatures living on these distant worlds. Who knows what we might discover next?
Exoplanets come in all shapes and sizes. Some are gas giants, like Jupiter and Saturn, while others are rocky planets, like Earth and Mars. Some are incredibly hot, while others are freezing cold. And some might even have the right conditions for life to exist! There are even planets that being evaporated by their star(like our sun), one of them is WASP-12b which is slowly turning into gas because of this
Finding exoplanets is a tricky business. Scientists use special telescopes like Kepler and Transiting Exoplanet Survey Satellite (TESS) to look for changes in the light from stars. When a planet passes in front of its star, it blocks a little bit of the star's light. Scientists can measure this dimming and figure out if there's a planet orbiting the star.Some such telescopes are the Hubble space telescope and The James webb telescope. These telescopes have discovered exoplanets with water vapor in their atmosphere and even galaxies that were formed just a few million years after the big bang. How does this help you ask? Well with the help of finding exoplanets with water vapor in their atmosphere ,there maybe a chance that there is life in the universe and with the help of the galaxies that were some of the first ones to be formed we can find out about how the universe came into being and about the big bang and early universe.
