By studying the chemical composition of these planets' atmospheres, researchers hope to find definitive evidence of life elsewhere in the universe.

Over the past few decades, astronomers have discovered thousands of planets orbiting stars beyond our own solar system.

Known as exoplanets, these distant worlds range from rocky, Earth-sized spheres to massive gas giants larger than Jupiter.

Detecting these bodies is a complex task because they are often obscured by the intense glare of their host stars.

To overcome this, scientists use sensitive telescopes like the James Webb to observe the tiny dip in light as a planet passes in front of its star.
