Jupiter's North Pole
Jupiter's North Pole is the northernmost point of Jupiter. Like Jupiter's South Pole, it has a bluer surface color than the rest of Jupiter Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a gas giant with a mass more than two and a half times that of all the other planets in the Solar System combined, but slightly less than one-thousandth t .... It was first imaged in July 2016 with the Juno probe entering the polar orbit of Jupiter. At the same time, its polar cyclone was discovered, measuring just over 3000 km, surrounded by eight smaller cyclones which each measure 2400–2800 km in diameter. They are almost half the size of the South Pole cyclones and form a close to regular eight-corner. All of them turn counterclockwise. In contrast to the South Pole, where in 2019 to the five peripheral cyclones added a sixth, at the North Pole this structure of "1+8", at least until the end of 2020, remained stable. Its stability is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclone Storms Encircle Jupiter's North Pole, Captured In Infrared Light By NASA's Juno Spacecraft
In meteorology, a cyclone () is a large air mass that rotates around a strong center of low atmospheric pressure, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as viewed from above (opposite to an anticyclone). Cyclones are characterized by inward-spiraling winds that rotate about a zone of low pressure. The largest low-pressure systems are polar vortices and extratropical cyclones of the largest scale (the synoptic scale). Warm-core cyclones such as tropical cyclones and subtropical cyclones also lie within the synoptic scale. Mesocyclones, tornadoes, and dust devils lie within smaller mesoscale. Upper level cyclones can exist without the presence of a surface low, and can pinch off from the base of the tropical upper tropospheric trough during the summer months in the Northern Hemisphere. Cyclones have also been seen on extraterrestrial planets, such as Mars, Jupiter, and Neptune. Cyclogenesis is the process of cyclone formation and ...

Jupiter's South Pole
For the first time the South Pole of Jupiter was photographed in detail by the Juno spacecraft, which arrived to Jupiter in July 2016 and for the first time in history entered the polar orbit of Jupiter. At the same time, six cyclones were discovered at the South Pole: one in the center and five around it (their centers formed a close to regular pentagon), each about 4,500 km (2,800 mi.) in diameter, with a wind speed of about 360 km/h (220 mph), and all of them twisted clockwise. A similar picture at the North Pole of Jupiter presents nine cyclones of similar size: one in the center, and eight around it, rotating counterclockwise. For more than three years the structure of cyclones at both poles of the nearest to us gas giant remained stable, but on November 3, 2019, on the 22nd rotation, "Juno" found the birth of a new cyclone at the South Pole: it quickly "pushed" the previous (although still has a smaller size, about 800 km), and now the centers of peripheral cyclones pole fo ...

Jupiter
Jupiter is the fifth planet from the Sun and the List of Solar System objects by size, largest in the Solar System. It is a gas giant with a mass more than two and a half times that of all the other planets in the Solar System combined, but slightly less than one-thousandth the mass of the Sun. Jupiter is the List of brightest natural objects in the sky, third brightest natural object in the Earth's night sky after the Moon and Venus, and it has been observed since Pre-history, prehistoric times. It was named after the Jupiter (mythology), Roman god Jupiter, the king of the gods. Jupiter is primarily composed of hydrogen, but helium constitutes one-quarter of its mass and one-tenth of its volume. It probably has a rocky core of heavier elements, but, like the other giant planets in the Solar System, it lacks a well-defined solid surface. The ongoing contraction of Jupiter's interior generates more heat than it receives from the Sun. Because of its rapid rotation, the planet' ...

Juno (spacecraft)
''Juno'' is a NASA space probe orbiting the planet Jupiter. It was built by Lockheed Martin and is operated by NASA Jet Propulsion Laboratory. The spacecraft was launched from Cape Canaveral Air Force Station on August 5, 2011 UTC, as part of the New Frontiers program. ''Juno'' entered a polar orbit of Jupiter on July 5, 2016, UTC, to begin a scientific investigation of the planet. After completing its mission, ''Juno'' will be intentionally deorbited into Jupiter's atmosphere. ''Juno'' mission is to measure Jupiter's composition, gravitational field, magnetic field, and polar magnetosphere. It will also search for clues about how the planet formed, including whether it has a rocky core, the amount of water present within the deep atmosphere, mass distribution, and its deep winds, which can reach speeds up to . ''Juno'' is the second spacecraft to orbit Jupiter, after the nuclear powered ''Galileo'' orbiter, which orbited from 1995 to 2003. Unlike all earlier spacecr ...
