Researchers say they have confirmed an exoplanet—a planet orbiting another star—using NASA’s new James Webb Space Telescope (JWST) for the very first time.

The planet, known as “LHS 475 b”, is almost exactly the same size as Earth. Researchers say the planet is a few hundred degrees warmer than Earth.
