Raining Perseids
Explanation: Comet dust rained down on planet Earth last August, streaking through dark skies in the annual Perseid meteor shower . So, while enjoying the anticipated space weather, astronomer Fred Bruenjes recorded a series of many 30 second long exposures spanning about six hours on the night of August 11/12 using a wide angle lens. Combining those frames which captured meteor flashes , he produced this dramatic view of the Perseids of summer . Although the comet dust particles are traveling parallel to each other, the resulting shower meteors clearly seem to radiate from a single point on the sky in the eponymous constellation Perseus. The radiant effect is due to perspective , as the parallel tracks appear to converge at a distance. Bruenjes notes that there are 51 Perseid meteors in the composite image , including one seen nearly head-on. This year, the Perseids Meteor Shower will peak in the early morning hours on Friday, August 12.
