Jupiter’s trademark Great Red Spot may be shrinking, but it’s not going down without a fight.

Amazing new maps of the Jupiter by the Hubble Space Telescope reveal that the Great Red Spot, a massive storm about twice the diameter of Earth, is slowing the speed at which it shrinks. The Jupiter maps, first in series of annual portraits of the outer planets, also reveal rare wave structures that scientists haven’t seen for nearly 40 years.

NASA used the new Hubble images to create a stunning video of Jupiter’s changing atmosphere. The images, taken over a 10-hour period, created two massive maps of the entire planet, allowing scientists to measure the speeds of Jupiter’s winds, identify different events in its atmosphere, and track changes in the outer layers of the planet.
