Jupiter's Great Red Spot, a vast storm system visible on the gas giant since at least the 1830s and perhaps the 1660s, is reportedly "unraveling."
“I haven’t seen this before in my 17-or-so years of imaging Jupiter,” reports veteran observer Anthony Wesley of Australia, who photographed a streamer of gas detaching itself from the GRS on May 19th: The plume of gas is enormous, stretching more than 10,000 km from the central storm to a nearby jet stream that appears to be carrying it away. Wesley says that such a streamer is peeling off every week or so.
