Astronomy Picture of the Day [1]Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2025 March 9 [2]The image shows the north pole of Jupiter in red (infrared) light. Many cyclonic swirls surround the pole. Please see the explanation for more detailed information. Cyclones at Jupiter's North Pole Image Credit: [3]NASA, [4]JPL-Caltech, [5]SwRI, [6]ASI, [7]INAF, [8]JIRAM Explanation: Why are there so many cyclones around the north pole of Jupiter? [9]The topic is still being researched. NASA's robotic [10]Juno mission orbiting Jupiter took data in 2018 that was used to construct [11]this stunning view of the curious cyclones at Jupiter's north pole. Measuring the [12]thermal emission from Jovian cloud tops, the [13]infrared observations are not restricted to the [14]hemisphere illuminated by sunlight. [15]They reveal eight cyclonic features that surround a cyclone about 4,000 kilometers in diameter, just offset from the giant planet's geographic north pole. Similar data show a cyclone at the [16]Jovian south pole with five circumpolar cyclones. The south pole cyclones are slightly larger than their northern cousins. [17]Oddly, data from the once Saturn-orbiting [18]Cassini mission has shown that Saturn's [19]north and [20]south poles each have only a single cyclonic [21]storm system.
