Only 75% of annual observations of the giant planet by NASA\u2019s Hubble Space Telescope between 1994 and 2022 reveal them. The dark ovals are much rarer close to in Jupiter&#8217;s north pole, where they appear in just a couple of the 25 annual images. The ovals are dark in ultraviolet light because they absorb more light than the surrounding atmosphere.<\/p>\n<h2 class=\"subhead-embed color-accent bg-base font-accent font-size text-align\">Dark Ovals<\/h2>\n<p>This is not the first time dark ovals have been found on Jupiter.
