What We Found When We X-rayed UranusSubmitted by chandra on Tue, 2021-03-30 10:33
We are pleased to welcome Affelia Wibisono, who received her Masters degree in Physics from Royal Holloway, University of London in 2012, as our guest blogger. She worked as a science communicator at London’s Science Museum and the Royal Observatory Greenwich before starting her PhD in 2018 at University College London’s Mullard Space Science Laboratory (MSSL). Her research interests are in X-ray emissions from planets in our Solar System, in particular how and why Jupiter produces intense X-ray auroras.
Huge, violent and exotic objects in space such as black holes, supernovae and quasars are what usually come to mind when one thinks about X-ray astronomy. But it’s the more humble X-ray sources found closer to home that my research group and I want to know more about. Many things in our Solar System emit X-rays, such as the Sun, comets, moons and even Pluto. Astronomers have also detected X-rays from the four rocky planets, Mercury, Venus, Earth and Mars, and from the gas giants Jupiter, and Saturn. However, efforts to find X-rays from Uranus in 2002 and 2017 were fruitless — or so we thought.
