Have you ever seen the <a href="/earth/Magnetosphere/aurora.html&edu=elem&dev=1">Southern or Northern Lights</a>? Earth isn't the only planet that puts on these beautiful light shows, which are also called the "<a href="/earth/Magnetosphere/aurora.html&edu=elem&dev=1">aurora</a>". Aurora have been seen at both <a href="/saturn/saturn_polar_regions.html&edu=elem&dev=1">poles of Saturn</a>, too, as well as at the poles of <a href="/jupiter/magnetosphere/jupiter_aurora.html&edu=elem&dev=1">Jupiter</a>. These "<a href="/earth/Magnetosphere/tour/tour_earth_magnetosphere_09.html&edu=elem&dev=1">curtains of light</a>" sometimes rise 1,200 miles (2,000 km) above the <a href="/saturn/atmosphere/S_clouds_overview.html&edu=elem&dev=1">cloud tops</a> near Saturn's poles. The <a href="/space_missions/HST.html&edu=elem&dev=1">Hubble Space Telescope</a> took this picture in 2004.<p><small><em>Image courtesy of NASA, ESA, J. Clarke (Boston University), and Z.
