**Geology**: Astronomers discover radiation-blasted Earth-size exoplanet for groundbreaking study of planetary **geology**
A team of astronomers has made a groundbreaking discovery of an Earth-size planet located about 55 light-years away from Earth. This planet, known as SPECULOOS-3 b, orbits its host star so closely that its days and nights are eternal due to tidal locking.
