James Webb telescope can take detailed photos of our own solar system’s planets and moons
Over the past few days, NASA has released stunning photos of nebulae, groups of galaxies and even the “deepest” view of the universe taken by the James Webb Space Telescope. Now, the agency has released images of something much closer to home that everyone’s new favorite telescope — sorry, Hubble! — has captured. When the James Webb team was calibrating the instrument, members took photos of Jupiter to see if it can be used to observe nearby celestial objects like moons and asteroids, as well other elements like planet rings and satellites. The answer, it turns out, is yes.
A photo taken by the telescope’s Near-Infrared Camera (NIRCam) instrument’s short-wavelength filter (above) clearly shows the gas giant’s distinct bands and its moon Europa. The Great Red Spot is also perfectly visible, even though it looks white due to the way the image was processed. When the NIRCam instrument’s 2.12 micron filter was used, the resulting image showed the Jovian moons Europa, Thebe, Metis and even Europa’s shadow near the Great Red Spot. And when the team used NIRCam’s 3.23 micron filter, the resulting image captured some of Jupiter’s rings, as you can see below:
