NASA’s Juno spacecraft continues to send back stunning images of the giant planet, including this view captured on 23 May at a distance of 7,900 kilometres (4,900 miles) during the probe’s 13th close flyby. For orientation, south is at upper left while north is toward lower right. The North Temperate Belt is the reddish-orange band just left of center, which rotates in the same direction as the planet. To the left of the belt is the bright North North Temperate Zone with high clouds likely made up of ammonia-ice or, possibly, ammonia ice and water. Darker regions are thought to be areas where clouds extend deeper into the atmosphere with warmer emissions detected by Juno’s infrared senors. Jupiter’s atmospheric bands become less evident toward the north polar regions at lower right where multiple cyclones and darker anticyclones rotate.
Scientists using the NASA/ESA Hubble Space Telescope have produced new maps of Jupiter that show the continuing changes in its famous Great Red Spot. The images also reveal a rare wave structure in the planet’s atmosphere that has not been seen for decades. This is the first in a series of annual portraits of the solar system’s outer planets which will help researchers study how they change over time.
