Astronomers discovers blue planet where it rains glass

The video discusses the extrasolar planet HD-1897 33B, located 63 light years away in the Vulpa constellation. It is a gas giant with a thick atmosphere of hydrogen and helium, possibly having a molten core. Classified as a hot Jupiter, it orbits close to its parent star. The Hubble Space Telescope observed changes in the planet's light spectrum, revealing its blue color. This hue is due to liquid glass rain and strong winds that scatter silicate particles in the atmosphere.
