﻿ Astronomy Picture of the Day [1]Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2022 April 27 [2]The featured image shows the planet Jupiter as seen by NASA's passing robotic spaceship Juno. A large dark spot seen on Jupiter is the shadow of Jupiter's moon Io. Please see the explanation for more detailed information. Moon Shadow on Jupiter Image Credit: [3]NASA/[4]JPL-Caltech/[5]SwRI/[6]MSSS; Processing & [7]License: Thomas Thomopoulos Explanation: What is that large dark spot on Jupiter? It's the shadow of [8]Ganymede, [9]Jupiter's largest moon. When [10]Jupiter's moons cross between the Jovian giant and the Sun, they [11]created shadows just like when the [12]Earth's moon crosses between the Earth and the Sun. Also like on Earth, if you were in a [13]dark shadow on Jupiter, you would see a moon completely [14]eclipse the Sun. Unlike on Earth, [15]moon shadows occur most days on Jupiter -- what's [16]more unusual is that a spacecraft was close enough to record one with a [17]high-resolution [18]image. That [19]spacecraft, Juno, was passing so close to [20]Jupiter in late February that nearby clouds and the dark eclipse shadow appear [21]relatively large. Juno has made many discoveries about our [22]Solar System's largest planet, including, recently, [23]rapidly expanding circular auroras.
