Photo Release: Hubble observes energetic lightshow at Saturn's north pole
{"Image ImageDescription": "This image is a composite of observations made of Saturn in early 2018 in the optical and of the auroras on Saturn\u2019s north pole region, made in 2017. In contrast to the auroras on Earth the auroras on Saturn are mainly visible in the ultraviolet \u2014 a part of the electromagnetic spectrum blocked by Earth\u2019s atmosphere \u2014 and therefore astronomers have to rely on space telescopes like the NASA/ESA Hubble Space Telescope to study them."}
