Our planet had a brief visitor the past couple months who promises to be back in about 50,000 years. if you missed this green guy, stay tuned. I figured I might not make it for another multi-thousand centuries so I better try for a selfie. Well, the selfie part didn’t work, however, in spite of the crappy weather here in northeast Ohio, I did manage a portrait of the comet more affectionally know as C/2022 E3 (ZTF). It zipped past the sun in January and started headed for really outer space when I caught up with it on February 14. It’s traveling at around 156,000 miles per hour so you have to look quick. It’s green because of sunlight interacting with carbon and cyanogen in the comet’s head.
