Explanation: From dark skies
above Heilongjiang province in northeastern China, meteors rain down on a wintry landscape in this beautiful composited night scene. The 48 meteors are part of last week's annual Geminid meteor shower. Despite
temperatures of -28 degrees C, all were recorded in camera exposures made during the peak hour of the celestial spectacle. They stream away from the shower's radiant high above the horizon near the two bright stars of the zodiacal constellation of the Twins. A very active shower
, this year the December 13-14 peak of the Geminids arrived just before the December 16 closest approach
of asteroid 3200 Phaethon to planet Earth. Mysterious 3200 Phaethon
is the Geminid shower's likely parent body.

It's probably coincidence, but the meteors seem TOO evenly spaced. Randomness (as in a star field) always has areas of high numbers of stars, and areas of no of stars. At least that (and that it's Pareidolia) is what I'm told when I notice lines of stars in many photos of our galaxy's stars.

Nice shot.... cold.... BRRRRR... and I complain when it is 50F in the mobile home....
We are cloudy and bitter cold, and overcast... and if it were not overcast, I don't think I would get out....

FWIW, the Geminid radiant moves about 13° in an hour.
