Lightshow alert! 👀 Astronomers using our @NASAHubble Space Telescope spotted auroras, or dancing lights, on Saturn’s north pole region. In contrast to the auroras on Earth, Saturn’s auroras are most easily imaged and studied in ultraviolet using space telescopes. Hubble allowed researchers to monitor the behavior of the auroras at Saturn's north pole over an extended period of time back in 2017 in order to create this composite image. The Hubble observations were coordinated with the "Grand Finale" of the Cassini spacecraft, when the spacecraft simultaneously probed the auroral regions of Saturn. Data allowed astronomers to learn more about Saturn’s magnetosphere, which is the largest of any planet in the Solar System other than Jupiter.Credit: NASA, ESA/Hubble, A. Simon and the OPAL Team, J.
