So-called “brown barges” are cyclonic storms in Jupiter’s atmosphere that are typically found in the giant planet’s relatively dark North Equatorial Belt but they are occasionally spotted om the South Equatorial Belt as well. The storms are difficult to detect visually because they tend to blend in with the surrounding areas. But occasionally, the darker material in the belt recedes and brown barges become easier to see against the lighter background. This image, capturing a brown barge in the South Equatorial Belt, was captured by NASA’s Juno Jupiter orbiter on 6 September as the probe made its 15th close flyby at a distance of 11,950 kilometres (7,425 miles) from Jupiter’s cloudtops. The color-enhanced JunoCam image was processed by citizen-scientist Kevin M. Gill.
Unbeknown to two European amateur astronomers 1000 miles apart capturing video of Jupiter through their telescopes in the early hours of Thursday, 17 March, their digital footage would subsequently show confirmation of a totally unexpected phenomenon — the likely impact of a small comet or asteroid on the edge of the solar system’s largest planet.
Observers in the British Isles and western Europe with a clear sky low to the east around 10pm local time on Wednesday, 27 January can see the rising 18-day-old waning gibbous Moon in a close conjunction with Jupiter, the solar system’s largest planet. Jupiter draws steadily closer to Earth and grows in apparent size over the coming weeks.
