NASA Just Shot the Closest-Ever Photos of Jupiter's Great Red Spot
Jupiter’s “Great Red Spot” (or G.R.S.) is a giant storm on the gas planet that has possibly existed for at least 350 years. NASA’s Juno spacecraft flew just 5,600 miles above the storm on Monday, snapping new photos that give us a beautiful view of this famous feature.
The distance between Juno and Jupiter is the closest any camera has gotten to the Great Red Spot, giving JunoCam the opportunity to show us Earthlings details we’ve never seen before.

APOD: 2017 July 15 - Close up of the Great Red Spot
Explanation: On July 11, the Juno spacecraft once again swung near to Jupiter's turbulent cloud tops in its looping 53 day orbit around the Solar System's ruling gas giant. About 11 minutes after perijove 7, its closest approach on this orbit, it passed directly above Jupiter's Great Red Spot. During the much anticipated fly over, it captured this close-up image data from a distance of less than 10,000 kilometers. The raw JunoCam data was subsequently processed by citizen scientists. Very long-lived but found to be shrinking, the Solar System's largest storm system was measure to be 16,350 kilometers wide on April 15. That's about 1.3 times the diameter of planet Earth.

APOD: 2017 July 16 - Lightning Eclipse from the Planet of the Goats
Explanation: Thunderstorms almost spoiled this view of the spectacular 2011 June 15 total lunar eclipse. Instead, storm clouds parted for 10 minutes during the total eclipse phase and lightning bolts contributed to the dramatic sky. Captured with a 30-second exposure the scene also inspired one of the more memorable titles (thanks to the astrophotographer) in APOD's now 22-year history. Of course, the lightning reference clearly makes sense, and the shadow play of the dark lunar eclipse was widely viewed across planet Earth in Europe, Africa, Asia, and Australia. The picture itself, however, was shot from the Greek island of Ikaria at Pezi. That area is known as "the planet of the goats" because of the rough terrain and strange looking rocks.
