"Scorching Discovery: Earth-sized Exoplanet with Lava Hemisphere Unveiled"

Scientists have discovered a new Earth-sized exoplanet, HD 63433 d, in a planetary system known for having two planets. The planet is extra hot, young, and tidally locked, with one side constantly facing its Sun-sized star. The planetary system is 500 million years old, making HD 63433 d the youngest Earth-sized planet known. The star in the system is a G-type star, similar to our Sun. The discovery was made using data from NASA's TESS, and the planet's dayside may resemble a "lava hemisphere" due to its scorching temperatures.

"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.
