Astronomers have discovered an Earth-sized world in orbit around an ultracool red dwarf star not much bigger than Jupiter. Designated SPECULOOS-3 b, the planet is about 55 light-years from Earth and takes about 17 hours to orbit once around its star. The star is dramatically cooler than the Sun but blasts out intense radiation that has likely scoured the planet's surface. Because the star is so dim, this planet is a perfect target for JWST.
