shows the moon slowly drifting through the frame. Since the arrival time and location
of each individual photon was recorded, we were able to transform into Europa's
rest-frame and generate these FUV image.
Additional non-transit observations are in the works.
Callisto Coordinate Transform
Callisto, Jupiter's second-largest moon, zipped through the edges of two recent observations
Taking advantage of STIS's unique time-tag mode, we were able to transform into
Callisto's rest-frame and generate this FUV image.
Note that the false-colors presented here represent flux intensity within a single bandpass (F25SRF2).
