Webb will investigate the potential hidden ocean beneath the moon Ganymede’s icy crust, and the “stealth volcanos” that have gone undetected on the fiery moon Io. The Solar System’s largest planet, Jupiter, is among Webb’s earliest targets, serving as a proving ground for the observatory’s sensitive instruments to image both the bright planet and its faint rings. Looking farther, Webb’s observations can give us a better picture of the seasonal weather and climate on the giant planets and their moons.

Hammel and the HST Comet Science Team and NASA. The Hubble telescope recorded this spectacular event. Outer Planets In July 1994, 21 chunks of comet Shoemaker-Levy 9 slammed into Jupiter. Mars’ history and potential future as a water-bearing planet may yield insights into Earth’s own story, especially the evolution of life. Does the atmosphere of Mars reveal a more habitable past? What altered the stability of its atmosphere? In addition to searching for water, geologists can use Webb to study the formation and evolution of global dust storms and cloud systems over dormant volcanoes. Webb can survey for-and follow up on-the findings of the Mars rovers and landers. The presence of water on Mars now and in the past is one of the driving forces for Martian exploration. Webb’s focus on infrared light provides astronomers with the ability to study features of planet surfaces and atmospheres they could not see in visible light. There is still a lot to discover close to home-how the planets, moons, and smaller bodies of the solar system are similar to Earth, and how they are different.Įxamining planetary systems and the origin of life is one of the James Webb Space Telescope’s core goals.

The infrared image (right) reveals features that could not be seen in visible light, including variations in the abundance and distribution of water-bearing minerals.
