The bright comet C/2023 A3 has emerged in the evening sky and will be easy to spot in coming nights. Look for Venus and the bright star Arcturus. Take half the distance between them; look down toward the western horizon. Best views will be through binoculars. 📷: Stellarium

Friends. These are lots of my all-time favorite images. I'm letting them go, frankly out of desperation. You can download them all and make prints or use as backgrounds on your devices. Pay whatever you think they're worth ❤️ buymeacoffee.com/angrytheinch drive.google.com/drive/folders/…

Insane light pillars in Central, Alberta this morning!! -30°C temps with -40°C windchill. I could only be out for 10 seconds at a time😱🥶 #atoptics #shareyourweather ᴛʀᴇᴇ ᴛᴀɴɴᴇʀ Jim Cantore WeatherNation Matthew Cappucci Mike Sobel The Weather Channel

Enjoy the view 🌎 This timelapse shows an aurora swirling through Earth’s atmosphere during Expedition 67 aboard the International Space Station.

A lens can perform the Fourier transform! 🔍 This is the 4F system: the first lens converts an image into its frequency components, and the second lens reconstructs it. By adding an aperture at the Fourier plane, we can filter out high frequencies. #Optics #Physics #b3d

My very own hashtag #ozzyosbourne moment? I had a bat flying in my face while researching darkness we measured light around bat roosts and improved the lighting while monitoring bat behavior.... R.I.P. Ozzy 🤘 #ozzy #bats #lightpollution
