Detail
Did you know that Jupiter has rings like Saturn?
Even the best Earth-based telescopes cannot see Jupiter’s rings. However, the Subaru Telescope was successful in capturing this image using infrared wavelengths.
This false-color composite image was created using three different wavelengths in infrared: H2O Ice (3.05 microns) in blue, L-band (3.77 microns) in green, and K’-band (2.20 microns) in red. Unlike Saturn's rings, which are primarily made up of water-ice particles, Jupiter's rings are composed mainly of dust. This image does not show blue, indicating the absence of water-ice in Jupiter’s rings.
