This image of the Perseid meteor shower was obtained in the night between 12 and 13 August 2007, when this recurrent summer phenomenon reached its intensity peak. The image was taken by ESA’s SPOSH camera during a 30-minute time frame, with 2-second exposures.
Stars appear as describing arcs around the pole star. The pole star itself shows up as a point, as it is almost stationary during the exposure time. The meteors are visible as streaks crossing the path of the stars.
