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.
