To help answer this question, the Hubble Space Telescope and the Cassini spacecraft monitored Saturn&#8217;s North Pole simultaneously during Cassini&#8217;s final orbits around the gas giant in September 2017. During this time, Saturn&#8217;s tilt caused its North Pole to be clearly visible from Earth. The featured image is a composite of ultraviolet images of aurora and optical images of Saturn&#8217;s clouds and rings, all taken recently by Hubble. Like on Earth, Saturn&#8217;s northern auroras can make total or partial rings around the pole. Unlike on Earth, however, Saturn&#8217;s auroras are frequently spirals &#8212; and more likely to peak in brightness just before midnight and dawn. In contrast to Jupiter&#8217;s auroras, Saturn&#8217;s auroras appear better related to connecting Saturn&#8217;s internal magnetic field to the nearby, variable, solar wind. Saturn&#8217;s southern auroras were similarly imaged back in 2004 when the planet&#8217;s South Pole was clearly visible to Earth. via NASA <a href=\"https:\/\/apod.nasa.gov\/apod\/ap180903.html\"><\/a><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Are Saturn&#8217;s auroras like Earth&#8217;s?
