Abstract:

Jupiter has been one of the biggest mysteries of solar system over years and astronomers rigorously trying to reveal its secrets. Since the accidental discovery of Jupiter’s radio signal in 1955 scientists continuously observing the planet in radio, UV and IR frequency. After ground based study for a long period, the researchers feel the necessity of a close look to the planet to solve the mystery of our solar system, origin and evolution of the gas giant, its dynamic magnetosphere, interior structure, atmospheric dynamics, chemical composition and its intense aurora. In pursuance of these aspects of astrophysics the space research institute NASA and Jet Propulsion Laboratory (JPL) added a new feather in the form of a fastest man made, solar powered space craft Juno. In this paper, we have critically discussed the different types of signal and radio burst that emits from Jupiter and their mechanism considering the vital role of its nearest moon Io followed by the exploration with earlier space probes and an overview of the new mission Juno. The space craft Juno is a highly equipped instrument with titanium made body having a unique polar orbit to reach very close to the planet than else before. After a five-year long journey Juno started to interact with the planet by crossing the bow shock and magnetopause several times through which the purpose of observing Jupiter’s magnetic field has been solved. We have emphasized the radio and plasma wave observations in Jupiter’s polar magnetosphere during Juno’s first perijove pass on August 27, 2016 (DYO 240), electron energy spectrogram and the plasma wave signals from Jupiter’s ionosphere that observed by Juno.
