ESA's Cheops mission has been studying an ultra-hot exoplanet around a nearby star and discovered its metallic clouds reflect about 80% of the light shining on it from its host star. The planet is about the size of Neptune, and its high-temperature clouds are filled with silicate mixed with metals like titanium. The planet takes only 19 hours to orbit its star, and astronomers are puzzled why it hasn't had its atmosphere blown away, leaving only bare rock behind. The metal clouds might actually ...
