Time-lapse sequence from the approach of Voyager 1 to Jupiter in 1979, showing the motion of atmospheric bands, and the circulation of the Great Red Spot. The momentary black spots are shadows cast by Jupiter's moons. Jupiter's Great Red Spot rotates counterclockwise, with a period of about 4.5 Earth days, [24] or 11 Jovian
New observations of Jupiter’s Great Red Spot captured by the Hubble Space Telescope show that the 190-year-old storm wiggles like gelatin and shape-shifts like a squeezed stress ball.
The closest in the past 1,000 years was in 1761, when Mars and Jupiter appeared to the naked eye as a single bright object, according to Giorgini. Looking ahead, the year 2348 will be almost as close.
Now, they think they know just how old it is and how the cyclone formed in Jupiter’s atmosphere. Jupiter’s Great Red Spot is different from what an Italian astronomer observed in 1665 Skip to ...
Triple conjunction Mars–Jupiter. 2475 Pluto's orbit brings it closer to the Sun than Neptune for the third time since its discovery. 2478 August 29 At 22:58 UTC, Mars will occult Jupiter. [31] [42] 2487–2719 Fragments (A–D) of the Great Comet of 1882 should return. [68] 2487 May 9 At 12:45 UTC, Mercury will occult Mars. [42] 2490 June 12
The Great Red Spot (GRS) is a persistent anticyclonic storm, 22° south of Jupiter's equator; observations from Earth establish a minimum storm lifetime of 350 years. [ 84 ] [ 85 ] A storm was described as a "permanent spot" by Gian Domenico Cassini after observing the feature in July 1665 with his instrument-maker Eustachio Divini . [ 86 ]
Look up to the sky Wednesday morning and you'll see what astronomers call a planetary conjunction as Jupiter and Mars appear to be close together.
The Great Red Spot on Jupiter is, by far, the largest extraterrestrial anticyclone (or cyclone) known. The Great Red Spot is located in the southern hemisphere and has wind speeds greater than any storm ever measured on Earth. New data from Juno found that the storm penetrates into Jupiter's atmosphere about 320 km (200 mi).
