"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.
