During its fifteenth flyby of Jupiter , NASA ’s Juno spacecraft captured a rare image of a Jovian “ brown lighter . ” It ’s not nearly as impressive or picturesque as the Great Red Spot , but this big brown splotch is yet another admonisher of many complex atmospherical processes materialise on our Solar System ’s big planet .
Also known as brown oval , brown barge are large cyclonal regions that typically make in Jupiter ’s dark North Equatorial Belt or , less frequently , in the dark South Equatorial Belt , consort to NASA . This particular violent storm is locate in the southern belted ammunition .
Juno , which has been revolve Jupiter since July 2016 , have this picture on September 6 , 2018 at a length of 7,425 miles ( 11,950 klick ) from the planet ’s cloud tops . The colour - enhanced image was created by citizen scientist Kevin M. Gill , who used information from the spacecraft ’s JunoCam , which is accessible to the populace . NASA says it ’s the first skinny - up view of this atmospheric phenomenon , providing an unprecedented glance of the elaborate structures within the storm .
Brown oval are typically strong to see , but this time we got favorable . As NASA describes in a press release , “ They can often be difficult to detect visually because their people of color blends in with the moody surroundings . At other time , as with this image , the dark belt cloth recedes , creating a lighter - colored background signal against which the brownish barge is more conspicuous . ”
This atmospherical feature is evocative of Jupiter ’s Great Red Spot — an anticyclonic storm that ’s been continuously observed by astronomer for the past 350 days . Unlike the unyielding Great Red Spot , however , brown flatboat do n’t last very long . This storm will eventually turn tail its grade , shoot , and likely go through a new bike of shakeup . Most features within Jupiter ’s smash and zone are unawares - lived , lasting anywhere from three to 15 years .
Juno has now complete 15 flybys of the flatulence hulk . Its next nigh meeting will happen on October 29 , 2018 . The good news is that Juno is still less than halfway through its mission;the spacecraft is scheduled to make another 20 flybys , the terminal one occurring on July 30 , 2021 . Hopefully there will be plenty more brown splotches and other exotic phenomenon in the months and years to make out .
