Enhanced: The Dolphin Cloud on Jupiter

Explanation: Do you see the dolphin-shaped cloud on Jupiter? The cloud was visible last year during perijove 16 , the sixteenth time that NASA's robotic spacecraft Juno passed near Jupiter since it arrived in mid-2016. During each perijove, Juno passes near a slightly different part of Jupiter's cloud tops. The dolphin shape may be surprising but is not scientifically significant -- clouds on Jupiter and Earth are constantly shifting and can temporarily mimic many familiar shapes . The cloud appears in Jupiter's South Temperate Belt (STB), a band of dark and dropping clouds that rings the planet and also contains Oval BA , dubbed Red Spot Jr. The featured image was digitally processed to enhance color and contrast. Juno's next swoop near Jupiter -- perijove 20 -- will occur on late May.
