The Great Red Spot on Jupiter is a massive storm or cyclone that measures about 16000 km in diameter.

Largest known storm in the solar system, the Great Red Spot has possibly existed for more than 350 years.

The spot has been under the observations since 1830.

The spot appears as a deep red sphere surrounded by layers of pale yellow, orange and white.

The storm is believed to be shrinking in the recent years.

Juno spacecraft was launched in August 2011 from Cape Canaveral, Florida as part of NASA's New Frontiers program.

The spacecraft was named from Greco-Roman mythology.

It has been orbiting solar system’s largest planet Jupiter since July 2016.

It is orbiting Jupiter pole to pole from 5000 kilometers above planet’s cloud tops.

Juno's mission is to understand the origin and evolution of Jupiter and investigate the existence of its core.

It also aims to map Jupiter’s intense magnetic field and measure the amount of water and ammonia in the deep atmosphere of Jupiter.

Early science results from NASA's Juno mission portray Jupiter as a turbulent world with complex interior structure, energetic polar aurora and huge polar cyclones.

The mission life of Juno is till February 2018.
