Jupiter image processing technique

These six images demonstrate a new imaging technique, which allowed astronomers to make a sharper image of the triple eclipse on Jupiter. The Hubble Space Telescope took rapid-fire snapshots of Jupiter as it swung through the observatory's field of view. The top row of images shows three of those snapshots. Astronomers then combined the images, accounting for the planet's rotation between exposures, to obtain the sharper photo. The bottom row shows the sharper images. Astronomers added 20 exposures together to make each image.
