This undated composite handout image provided by NASA, taken by the Hubble Space Telescope, shows the planet Jupiter and the The Great Red Spot in 2014, left; in 1995, top right; 2009, center right; and 2014, bottom right. Jupiter’s signature Great Red Spot is on a cosmic diet, shrinking rapidly before our eyes. Astronomers using the Hubble Space Telescope calculate that the spot, a giant long-lasting storm, is narrowing by about 580 miles a year, much faster than before. In the late 1800s the red spot was an elongated oval 25,500 miles wide. Now it’s a svelte circle that’s 10,250 miles across. (Photo by AP Photo/NASA)
