"Astronomers Discover Ultra-Hot Earth-Sized Exoplanet with Lava Hemisphere"

Astronomers have discovered an Earth-sized exoplanet with a hemisphere of molten lava and another hemisphere tidally locked in perpetual darkness. The discovery was presented at a meeting of the American Astronomical Society and detailed in The Astronomical Journal. Another paper in Astronomy and Astrophysics described the finding of a rare small, cold exoplanet with a massive outer companion. The Transiting Exoplanet Survey Satellite (TESS) aims to identify planets orbiting bright stars close to Earth, allowing follow-up observations to determine their compositions and atmospheres. This discovery sheds light on the diverse conditions of exoplanets and the potential for supporting life.
