﻿ 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. 2020 February 25 IFRAME: [2]https://www.youtube.com/embed/-N7nRh5v1Iw?rel=0 Jupiter's Magnetic Field from Juno Video Credit: [3]NASA, [4]JPL-Caltech, [5]Harvard U., [6]K. Moore et al. Explanation: How similar is Jupiter's magnetic field to Earth's? NASA's robotic [7]Juno spacecraft has found that Jupiter's magnetic field is [8]surprisingly complex, so that the [9]Jovian world does not have single magnetic poles like our [10]Earth. A snapshot of [11]Jupiter's magnetic field at one moment in time, as animated from Juno data, appears in the [12]featured video. Red and blue colors depict [13]cloud-top regions of strong positive (south) and negative (north) magnetic fields, respectively. Surrounding the planet are imagined lines of constant [14]magnetic field strength. The first sequence of the animated video starts off by showing what appears to be a relatively [15]normal dipole field, but soon a [16]magnetic region now known as the Great Blue Spot rotates into view, which is not directly aligned with [17]Jupiter's rotation poles. Further, in the second sequence, the [18]illustrative animation takes us over one of Jupiter's spin poles where red magnetic hotspots are revealed to be extended and sometimes even annular. A better understanding of [19]Jupiter's magnetic field may give clues toward a better understanding of [20]Earth's [21]enigmatic planetary [22]magnetism.
