This illustration compares the atmospheres of two "hot Jupiter"-class planets orbiting very closely to different sunlike stars. The planets are too far away for the Hubble Space Telescope to resolve any details. Instead, astronomers measured how the light from the parent stars is filtered through each planet's atmosphere. Hubble was used to measure the spectral fingerprint caused by the presence of water vapor in the atmosphere. HAT-P-38 b did have a water signature, indicating the upper atmosphere is free of clouds or hazes. By contrast, a very similar hot Jupiter, WASP-67 b, showed no water vapor, suggesting that most of the planet's atmosphere is masked by high-altitude clouds.
