It&#8217;s the shadow of Jupiter&#8217;s most volcanic moon Io. Since Jupiter shines predominantly by reflected sunlight, anything that blocks that light leaves a shadow. If you could somehow be in that shadow, you would see a total eclipse of the Sun by Io. Io&#8217;s shadow is about 3600 kilometers across, roughly the same size as Io itself &#8212; and only slightly larger than Earth&#8217;s Moon. The featured image was taken last month by NASA&#8217;s robotic Juno spacecraft currently orbiting Jupiter. About every two months, Juno swoops close by Jupiter, takes a lot of data and snaps a series of images &#8212; some of which are made into a video. Among many other things, Juno has been measuring Jupiter&#8217;s gravitational field, finding surprising evidence that Jupiter may be mostly a liquid. Under unexpectedly thick clouds, the Jovian giant may house a massive liquid hydrogen region that extends all the way to the center. via NASA <a href=\"https:\/\/apod.nasa.gov\/apod\/ap191007.html\"><\/a><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>What&#8217;s that dark spot on Jupiter?
