Hot Jupiters are exoplanets, similar to Jupiter in size and mass, but extremely close to their suns. Water exists there, but the amount of it still remains a mystery to astronomers.

Scientists Discovered How Hot Jupiters Hide Water

Previous studies using the Hubble space telescope showed that there are less water on hot Jupiters than it had been assumed in the theory. Now the reason for this discrepancy is cleared up. Comparing the data obtained using the Hubble and Spitzer telescopes when observing the ten exoplanets, the experts found that some hot Jupiters had a dense atmosphere and kind of clouds. In the optical range celestial bodies appear larger than in the infrared one. In particular cloudiness, according to scientists, prevents to establish the true amount of water. These data has to be confirmed by the successor of Hubble, the James Webb telescope.
