An interstellar visitor


Gerald Rhemann, taken from Farm Tivoli, Namibia

The interstellar comet 3I/ATLAS shows off a complex tail structure — plus an anti-tail, possibly caused by the nucleus emitting dust from its warmer, sunlit side. This shot was taken on Dec. 2 with a 12-inch f/3.6 astrograph and 38 minutes of LRGB exposure.
