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’s Juno Spacecraft works with Hubble Telescope, Gemini Observatory to examine Atmosphere of Jupiter

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA’s Hubble Space Telescope and the ground-based Gemini Observatory in Hawaii have teamed up with the Juno spacecraft to probe the mightiest storms in the solar system, taking place more than 500 million miles away on the giant planet Jupiter.

A team of researchers led by Michael Wong at the University of California, Berkeley, and including Amy Simon of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and Imke de Pater also of UC Berkeley, are combining multiwavelength observations from Hubble and Gemini with close-up views from Juno’s orbit about the monster planet, gaining new insights into turbulent weather on this distant world.

This graphic shows observations and interpretations of cloud structures and atmospheric circulation on Jupiter from the Juno spacecraft, the Hubble Space Telescope and the Gemini Observatory. By combining the Juno, Hubble and Gemini data, researchers are able to see that lightning flashes are clustered in turbulent regions where there are deep water clouds and where moist air is rising to form tall convective towers similar to cumulonimbus clouds (thunderheads) on Earth.

Ryan Hartman led the Preds with his two goal effort, that gave Nashville all they would need on the night. 

The Predators had struggled this season at home, where their only three losses had occurred in Nashville.  The Predators outshot the Golden Knights, 28-24 on the night.

Reilly Smith scored the first goal of the Knight for Vegas at 17:14 of the first period when his snapshot beat Predators goalie, Juuse Saros on the high side and Vegas led 1-0.

NASA Juno Spacecraft discovers origin of Jupiter’s Lightning

 

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Ever since NASA’s Voyager 1 spacecraft flew past Jupiter in March, 1979, scientists have wondered about the origin of Jupiter’s lightning. That encounter confirmed the existence of Jovian lightning, which had been theorized for centuries.

But when the venerable explorer hurtled by, the data showed that the lightning-associated radio signals didn’t match the details of the radio signals produced by lightning here at Earth.

In a new paper published in Nature today, scientists from NASA’s Juno mission describe the ways in which lightning on Jupiter is actually analogous to Earth’s lightning. Although, in some ways, the two types of lightning are polar opposites.
