     NASA's Juno mission provided a depths of Jupiter's great red spot. From the data collected from Juno spacecraft in July of 2017 reveals the iconic feature of the great red spot and other information include the existence of radiation zones. It had found that the giant storm prevailing for years is almost 300 kilometers wide which is equal to the half of our earth, so that it penetrates into the spot. This identification was made by one of the Juno instrument called Juno's Microwave Radiometer. The instrument has capacity to observe and collect data deep below the clouds of the Jupiter. It has been providing excellent information about the great red spot since its launch.


      Jupiter's great red spot is a giant cloud of crimson-coloured located in the southern hemisphere. It rotates at greater speed in anticlockwise direction. Data from Juno showed that the width of the red-spot is about 16,000 kilometers (normally equals to 1.3 times the width of our Earth). It also found that the res-spot is 50-100 times deeper than the oceans.The storm in this red-spot has been prevailing since 1830, that is more than 350 years. Earlier NASA missions like Voyager-1 and Voyager-2 visited the Jupiter and its red-spot in 1979, these twin spacecraft reported that the red-spot was two times the width of our Earth. The great red-spot will appear like deminishing in size, the future of this red-spot in mystery.

Radiation Zone:

     Juno also detected new radiation zone near the equator which is just above the giant atmosphere. The zone contains mostly of hydrogen, oxygen and sulfur ions circulating at a speed of light. This new radiation zone was detected by Juno's Jupiter Energetic Particle Detector instrument (JEDI). The energetic particles are moving fast and have no electric charges. The zone have high-energy ion population which was detected and monitored by Juno's Stellar Reference Unit-1 star camera. Large amount of images and data were collected.

About Juno Mission:

     Juno spacecraft was launched on 5 August 2011, from Cape Canaveral Air force station, Florida.  After few years it arrived Jupiter on 4 July 2016. From its arrival it had completed nine science pass around the Jupiter. The last science pass was on 16 December 2017. During its flybys Jupiter's clouds, atmosphere, great red-spot and radiation zone was explored including its magnetosphere. Juno mission is a part of NASA"s New Frontiers Program and the spacecraft was built by Lockheed Martin Space Systems, part of Jet Propulsion Laboratory, Caltech in Pasadena, California.
