These light displays are generated in the upper <a href=\"https:\/\/www.foxweather.com\/category\/atmosphere\" target=\"_blank\" rel=\"noopener\">atmosphere<\/a> from energetic particles near the planet\u2019s magnetic poles. According to those findings, a full rotation or &#8220;day&#8221; on Uranus is 17 hours, 14 minutes and 52 seconds long, which is 28 seconds longer than the estimate calculated from Voyager 2 data in 1986.<\/p>\n<p data-v-438398f6=\"\">Auroras are a known phenomenon on Earth, <a href=\"https:\/\/www.foxweather.com\/category\/jupiter\" target=\"_blank\" rel=\"noopener\">Jupiter<\/a> and <a href=\"https:\/\/www.foxweather.com\/category\/saturn\" target=\"_blank\" rel=\"noopener\">Saturn<\/a>.
