NASA’s Juno Spacecraft data reveals Shallow Lightning, Mushballs on Jupiter

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – New results from NASA’s Juno mission at Jupiter suggest our solar system’s largest planet is home to what’s called “shallow lightning.” An unexpected form of electrical discharge, shallow lightning originates from clouds containing an ammonia-water solution, whereas lightning on Earth originates from water clouds.

Other new findings suggest the violent thunderstorms for which the gas giant is known may form slushy ammonia-rich hailstones Juno’s science team calls “mushballs”; they theorize that mushballs essentially kidnap ammonia and water in the upper atmosphere and carry them into the depths of Jupiter’s atmosphere.

NASA - National Aeronautics and Space AdministrationPasadena, CA –  On Friday, July 12th, 2019, at around 2:00pm local time, NASA’s Atmospheric Infrared Sounder (AIRS), aboard the Aqua satellite, captured imagery of Tropical Storm Barry in the Gulf of Mexico. According to the National Hurricane Center, Barry is expected to make landfall over the Louisiana coast on Saturday, likely as a hurricane.

In the infrared AIRS image, the large purple area indicates very cold clouds that have been carried high into the atmosphere by deep thunderstorms. These clouds are associated with heavy rainfall. Warmer areas with shallower rain clouds are shown in blue and green. And the orange and red areas represent mostly cloud-free air.
