The far ultraviolet images revealed that the front edges of the shimmering auroral curtains, which can stretch 1000 kilometers tall on Saturn, raced across the planet's surface at more than 4 kilometers per second — about three times faster than the planet rotates, the researchers report in a forthcoming issue of Geophysical Research Letters.

Images of the sun in the
far ultraviolet and in X-rays (acquired most recently by the Solar and Heliospheric Observatory spacecraft, the Yohkoh satellite, and the NIXT rockets) show that the heating of the corona is localized in solar active regions, which indicates the important role played by the magnetic field.
Then, they combined the spectra with infrared
images of the Spitzer Space Telescope, the Herschel Space Observatory, and optical
images of the Hubble Space Telescope, to create a complete multi-wavelength picture of their galaxies: from rest - frame
ultraviolet to rest - frame
far - infrared.
