A frosty Comet ZTF (C/2022 E3) joins snow-covered Mount Etna in Sicily on January 24, 2023. This scene is exactly how photographer Dario Giannobile saw it through a 300-mm focal-length lens, but to make the comet pop he composited the foreground image with 27 tracked time exposures. The mountain is an active volcano as evidenced by smoke billowing from fumaroles. Comet ZTF exhibits both a dust tail (pointing upward) and a fainter antitail extending in the opposite direction.
