This artist's rendering shows the gas giant Kepler-7b, left, and Jupiter, right. The cloud map shows that clouds cover the western side of the gaseous planet, leaving the east cloud-free. Dr Demory and his colleagues speculate the clouds are made up of minerals containing silicates. Image credit: NASA / JPL-Caltech / MIT.
