The Morning After: The Webb Telescope discovers an exoplanet almost the same diameter of Earth

The James Webb Space Telescope (JWST) has recorded another inaugural milestone: its first confirmed discovery of an exoplanet. LHS 475 b is just 41 light years away and has a diameter 99 percent of Earth's. But there's more work to be done. The JWST should be able to figure out the atmospheres of Earth-sized exoplanets. The research team is still working to determine what, if any, sort of atmosphere the rocky mass may have.
