TL;DR Summary

Scientists have discovered a scorching exoplanet, LTT9779b, with temperatures reaching up to 2,000 degrees Celsius. The planet, about the size of Neptune, has metal and glass-like clouds that reflect light "like a mirror." This discovery challenges previous assumptions about the existence of planets with atmospheres so close to their star. The high reflectivity of LTT9779b's clouds prevents it from getting too hot and evaporating, while its metallic composition makes it heavier and harder to blow away. Further observations from telescopes like Hubble and James Webb are expected to provide more insights into this intriguing exoplanet.
