Synopsis
Sequence of Chandra Earth Aurora Images. MPEG The bright arcs in this sample of Chandra images show low-energy X-rays (0.1 - 10 kilo electron volts) generated during auroral activity. The images are approximately 20-minute scans during which Chandra was pointed at a fixed point in the sky and the Earth's motion carried the auroral regions through the field of view. The estimated altitude of the X-ray emission is 100 km. Auroras are produced by solar storms that disturb Earth's magnetic field…
