Contractors are seen working on a nearly completed floating solar panel array on the Queen Elizabeth II Reservoir near Walton-on-Thames in south west London, Monday, March 21, 2016. The floating array will consist of just over 23,000 solar photo-voltaic panels and within its first year will generate an estimated 5.8 million kilowatt hours of electricity. The arrays will help produce power on both cloudy and sunny days. (AP)

According to a study published on March 22, 2016, solar storms are triggering X-ray auroras on Jupiter that are about eight times brighter than normal over a large area of the planet and hundreds of times more energetic than Earth’s "northern lights. The auroras, seen in purple, were captured by the Chandra X-Ray Observatory. (X-ray: NASA/CXC/UCL/W.Dunn et al, Optical: NASA/STSc)
