Video: Flash on Jupiter

Posted on Posted in NASA, TweetTagged , , Leave a comment

There has been a flash on Jupiter. A few days ago, several groups monitoring our Solar System’s largest planet noticed a two-second long burst of light. Such flashes have been seen before, with the most famous being a series of impactor strikes in 1994. Then, fragments of Comet Shoemaker-Levy 9 struck Jupiter leaving dark patches that lasted for months. Since then, at least seven impacts have been recorded on Jupiter — usually discovered by amateur astronomers. In the featured video, variations in the Earth’s atmosphere cause Jupiter’s image to shimmer when, suddenly, a bright flash appears just left of center. Io and its shadow are visible on the right. What hit Jupiter will likely never be known, but considering what we do know of the nearby Solar System, it was likely a piece of rocky and ice — perhaps the size of a bus — that broke off long-ago from a passing comet or asteroid. via NASA https://ift.tt/3Ekughz

Wikipedia article of the day is Hurricane Humberto (2019). Check it out: Article-Link Summary: Hurricane Humberto was a large and powerful tropical cyclone that caused extensive wind damage in the British Overseas Territory of Bermuda during September 2019. It was the eighth named storm and third hurricane of the 2019 Atlantic hurricane season. Humberto formed on September 13, then paralleled the eastern coastline of Florida until September 16, when it turned sharply northeastward and became a hurricane. It reached peak intensity as a Category 3 hurricane on September 18. After its center passed within 65 miles (100 km) of Bermuda on September 19, the storm transitioned the next day to a potent extratropical cyclone. Rip currents killed one person in Florida and another in North Carolina. In Bermuda, peak surface winds of around 110 mph (180 km/h), with higher gusts, caused widespread damage to trees, roofs, crops, and power lines. About 600 buildings had roof damage, and L.F. Wade International Airport and the Bermuda Weather Service campus suffered property damage.
