MUSE video of the transit of Europa across the disc of Jupiter
This video sequence was created from many separate MUSE observations of the planet Jupiter during a transit of the moon Europe and its shadow.
To make the pictures for this time-lapse movie selected regions of the spectrum were extracted to form a set of colour images. They were selected to correspond to the wavelengths associated with methane absorption in Jupiter's atmosphere. This enhances the contrast with respect to Europa, which does not have this absorption and seems thus much brighter than in a normal image. The same process also enhances the contrast of the polar rings. Although these images are impressive they only represent a tiny fraction of the information in the full MUSE three-dimensional dataset.Źródło:
