APOD: Geminids and the Mittens (2022 Dec 25)

Image Geminids and the Mittens

Explanation: Asteroid 3200 Phaethon's annual gift to planet Earth always arrives in December. Otherwise known as the Geminid meteor shower, the source of the meteroid stream is dust shed along the orbit of the mysterious asteroid. Near the December 13/14 peak of the shower's activity, geminid meteors are captured in this night skyscape, composited from 22 images of starry sky taken before the moon rose over Monument Valley in the American southwest. The bright stars near the position of the shower's radiant are the constellation Gemini's twin stars Castor (blue) and Pollux (yellow). As Earth sweeps through the dusty stream, the parallel meteor trails appear to radiate from a point on the sky in Gemini due to perspective, and so the yearly shower is named for the constellation. From the camera's perspective, this view of three prominent buttes across Monument Valley also suggests appropriate names for two of them. The third one is called Merrick Butte.

The Merrick and the Mitten Buttes are sure the most beautiful buttes I ever did see. They sure are beautes! Also the 'Jim'inids are sure Jim-dandy looking meteor showers themselves. Merry Christmas.

Yes, "Mittens" with very spindly thumbs! More like the heads of two simumltaneously breaching sperm whales is what comes to mind first for me.

It’s happened again.

Someone, somewhere posted a mnemonic for me to remember which star is Pollux and which star is Castor. As always, I have forgotten the mnemonic, and do not remember which star is which. I just read the damn description, and in the few seconds since, I have completely forgotten which star is blue and which star is yellow!
