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.

    [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.

   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.
