The Cellar - Sept 27th, 2019 : Eye In The Sky

No, not the channel 13 traffic report.

Astronomers were using Hubble to monitor changes in Jupiter's immense Great Red Spot (GRS) storm. During the exposures, on 21 April 2014, the shadow of the Jovian moon Ganymede swept across the center of the GRS. Giving the giant planet the uncanny appearance of having a pupil in the center of a 16 000 kilometre wide eye.

16,ooo kilometre is 9,942 miles, remember the Earth is 7,918 miles (12,743 kilometre) in diameter.

At least it’s Jupiter and not Saturn.
