| ABSTRACT | |
| X-rays have been detected from a wide variety of worlds in our Solar System for many years. These range from terrestrial planets, to the Gas Giants, moons, comets and even Pluto. However, the first detection of X-rays from Uranus was announced this year using data from the Chandra X-ray Observatory (CXO), opening the possibility of studying the mysterious Ice Giant planets through their X-ray emissions. Results revealed that the X-ray flux from Uranus was higher than expected from scattered solar X-rays, hinting that there may be high energy processes producing X-rays at the planet. As for Jupiter and Saturn, this may include ring fluorescence and auroral emissions. XMM-Newton's superior sensitivity and spectral resolution will potentially revolutionise our understanding of this world. | |
