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.
Around 6:30am GMT on Friday 25 November, as nautical twilight starts for the centre of the UK, the 25-day-old waning crescent Moon lies just 2½ degrees away from largest planet Jupiter low in the southeastern sky. This juxtaposition of the two brightest objects in the dawn sky will be nicely framed in a typical binocular.
NASA’s Juno spacecraft is barreling toward a rendezvous with Jupiter after a 2.8 billion kilometre (1.7-billion-mile), five-year trip from planet Earth. The research probe’s main engine will ignite for 35 minutes to maneuver Juno into orbit, and engineers expect to receive confirmation of burn’s start at 0318 GMT Tuesday.
