The background includes bright star Sirius at the left, and Aldebaran and the Pleaides star cluster at the right side of the image. The meteor itself blazes through the constellation Orion. Its greenish trail begins just left of a yellow-tinted Betelgeuse and points back to the shower’s radiant in Gemini, just off the top of the frame. A rewarding catch for photographer Wally Pacholka, the spectacular image is one of over 1500 frames that he reports captured 48, mostly faint, Geminid meteors

What are the Geminids?

This meteor shower gets the name “Geminids” because it appears to radiate from the constellation Gemini. An observer in the Northern Hemisphere can start seeing Geminid meteors as early as December 6, when one meteor every hour or so could be visible. During the next week, rates increase until a peak of 50-80 meteors per hour is attained on the night of December 13/14. The last Geminids are seen on December 18, when an observer might see a rate of one every hour or so.

The appearance of this meteor shower seems to have been fairly sudden during the 1860s. It was first noted in 1862, when R. P. Greg (Manchester, England) found a radiant in the constellation Gemini for the period of December 10-12. B. V. Marsh and A. C. Twining (United States) independently discovered the activity around the same time. A. S. Herschel noted meteors emanating from Gemini during December 12/13, 1863, as well as three fireballs from near the same radiant in 1863 and 1864. During the 1870s, observations of the Geminids became more numerous as astronomers realized a new annual shower was active.
