Great Red Spot of Jupiter. Image taken by Cassini Spacecraft 

National Aeronautics Space Administration (NASA) Juno Spacecraft flied over Jupiter's great Red Spot on 10 July 2017. The above image was taken with Cassini's Narrow Wide Angle Camera on 29 December 2000. Red spot of Jupiter is one of the interesting feature of planet Jupiter to observe.

Robert Hooke and Giovanni Cassini in 17th century discovered the red spot of Jupiter and they suggested that the spot had been existing since four centuries and have persisted for a long period.Scientists suggest that the red spot has been shrinking. In 1979 Voyager spacecraft measured the diameter of red spot was 25000 km, but the modern Hubble Space Telescope image reveals that the red spot is shrunken to 15000 km. The red spot is very cold but have warm cyclone. The cyclone is almost equals to hurricane in our Earth` The reason for the redness of spot is still a mystery. Cyclones mostly consist of inert gases like Hydrogen and Helium. We can find many lightning storms like auroras in the poles.
