Epimetheus before Saturn

October 23, 2019

Wide-angle photograph of Epimetheus taken by the Cassini orbiter on 6 December 2015, through a clear filter. The image has been artificially colorized approximately as the human eye might see it.

Io above Jupiter

April 02, 2019

The innermost Galliean satellite, Io, coasts above the russet cloud decks of Jupiter. This Voyager 1 mosaic principally consists of 3 color composites made of orange-, green-, and blue-filtered images, all taken with the wide-angle camera on 4 March 1979. Gaps in coverage were filled by other 3-filter composites taken earlier or later the same day. North is to the right. Planet-spacecraft distance was some 1 million km.

Ganymede and Jupiter Global Voyager 2 Mosaic

April 02, 2019

The images for this composite were taken over a period of 4 hours on 8 July 1979 through orange, green, and blue or violet filters. Because of the long time span and Jupiter's rapid (10-hour) rotation, the cloud positions don't represent any real instantaneous view of Jupiter. Ganymede's shadow falls on the disk of Jupiter. Ganymede was actually much farther from Jupiter as seen by Voyager 2 during this observation; the distance between the two worlds has been reduced for aesthetic expediency. Voyage 2 was about 1.5 million kilometers away from Jupiter during this observation, but only 430,000 kilometers from Ganymede, which is why Ganymede appears so much larger than its shadow.
