This incredible timelapse footage was captured by photographer John Fox at the Space Geodesy Facility near Herstmonceux, East Sussex, UK... Operated by the British Geological Survey the Satellite Laser Ranger instrument is used to measure the distance of satellites in Earth's orbit to an accuracy of 10mm up to 20,000km range. John was given special permission to access the facility and took ten hours worth of time lapse videos (approx 9,000 photos) shot in freezing conditions (-4c one night) all

This incredible month-long timelapse footage of the Sun, captured recently by NASA's Solar Dynamics Observatory, demonstrates just how active the Sun is now. Vast sunspot groups trap energy in the form of plasma (superheated gas) within magnetic fields; when these break, massive solar flares emit that energy into space. If Earthbound, the flares give rise to Aurora, which explains why there has been so much activity lately! | Go Stargazing
