"Cheops Discovers Highly Reflective Exoplanet: A Mirror in Space"

Astronomers have discovered the most reflective exoplanet outside of our Solar System, named LTT9779b. This Neptune-sized planet reflects 80% of the light from its host star, making it as shiny as Venus. Despite its scorching temperatures, LTT9779b has managed to form metallic clouds that act as a mirror, preventing its atmosphere from being blown away. This finding challenges previous assumptions about the survival of Neptune-sized planets in the "Neptune desert" region. The observations were made by the Cheops space telescope.
