Jovian Auroral Discord
At the end of October a team of astronomers led by the University College London published a paper in Nature Astronomy reporting they had discovered that planet Jupiter’s northern and southern aurorae emit pulses of X-rays independently of each other. They made this discovery by analyzing data gathered by the ESA’s XMM-Newton and NASA’s Chandra X-ray observatories in May-June 2016 and March 2007. The astronomers observed that the X-ray emissions at the north pole were erratic […]
MAVEN spacecraft observes unexpected aurora and dust cloud
NASA reports that its Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft detected some unexpected auroral activity above the red planet for several days leading up to Christmas last year. The spacecraft, using its Imaging Ultraviolet Spectrograph (IUVS), observed a bright ultraviolet glow spanning Mar’s northern hemisphere. Observations from the spacecraft’s Solar Energetic Particle instrument points to the Sun as the source for an energetic burst of electrons detected at the beginning of the aurora. MAVEN’s Langmuir Probe and Waves […]
