    Default Gas Giant Jupiter And its Related Phenomena

    Spectacular aurora lights up Jupiter’s North Pole

    A stunning aurora above Jupiter’s North Pole has been captured by the Hubble telescope.

    The image of the Northern Lights was taken ahead of the arrival of NASA's spaceship Juno next week which will spend a year monitoring the largest planet in the Solar System.

    Jupiter is known for its colourful storms such as the Great Red Spot which swirls constantly in the planet’s atmosphere. But it’s powerful magnetic field also means it has spectacular light shows at its poles.

    Just like on Earth, auroras are created when high energy particles enter a planet's atmosphere near its magnetic poles and collide with atoms of gas.

    "These auroras are very dramatic and among the most active I have ever seen", said Jonathan Nichols from the University of Leicester, UK, and principal investigator of the study.

    "It almost seems as if Jupiter is throwing a firework party for the imminent arrival of Juno."

    To highlight changes in the auroras Hubble is observing Jupiter daily for around one month.

    Using this series of images it is possible for scientists to create videos that demonstrate the movement of lights at the poles, which cover areas bigger than the Earth.

    Not only are the auroras huge, they are also hundreds of times more energetic than auroras on Earth.

    And, unlike those on Earth, they never cease. Whilst on Earth the most intense auroras are caused by solar storms -- when charged particles rain down on the upper atmosphere, excite gases, and cause them to glow red, green and purple -- Jupiter has an additional source for its auroras.

    The strong magnetic field of the gas giant grabs charged particles from its surroundings, including particles thrown into space by its orbiting moon Io, known for its numerous and large volcanoes.

    NASA's Juno mission, which arrives at Jupiter’s orbit on July 4, aims to discover if a solid core lies beneath the dense atmosphere and what it driving the intense magnetic field.

    The 3.5 tonne spacecraft was launched in 2011 and it will be the first probe to travel so close to Jupiter’s deadly radiation belts.

    That is definitely stunning, but let us remember it is a composite.

    Juno's arrival is of course very exciting but I have more questions than will ever be answered about the space program as it is and about the 1.1 billion that was said to cost for the project.

    Juno probe returns close-up Jupiter pictures

    By Jonathan Amos
    BBC Science Correspondent
    3 hours ago

    The US space agency (Nasa) has released spectacular new images of Jupiter acquired by its Juno probe.
    The pictures show the swirling clouds of the gas giant at both its poles - views that no previous mission
    has managed to acquire in such detail.Juno captured the data last weekend as it made its first close
    approach to the planet since going into orbit in July.The flyby took the spacecraft just 4,200km above
    Jupiter's multi-coloured atmosphere.The 6MB of data gathered by Juno is still being analysed, but
    principal investigator Scott Bolton said new things were already obvious.

    "First glimpse of Jupiter's north pole, and it looks like nothing we have seen or imagined before. It's
    bluer in colour up there than other parts of the planet, and there are a lot of storms," the Southwest
    Research Institute scientist explained in a Nasa statement. "There is no sign of the latitudinal bands
    or zones and belts that we are used to - this image is hardly recognisable as Jupiter. "We're seeing
    signs that the clouds have shadows, possibly indicating that the clouds are at a higher altitude than
    other features."Jonathan Nichols from the University of Leicester, UK, is a member of the Juno
    mission's science team.He told the BBC that his colleagues were bowled over when they first saw the
    pictures: "The team's reaction was amazement. 'Look at these images; they are coming from Jupiter;
    we're flying over the pole for the first time!' It's just jaw-dropping."
