‘Absolutely insane airglow’

Those were the words of astrophotographer Yuri Beletsky, who captured this image on May 10 from Las Campanas Observatory in Chile.

Airglow is the light of excited atoms, high in Earth’s atmosphere. Yuri Beletsky captured this image on May 10, 2018 at Carnegie Las Campanas Observatory in Chile. You can see the telescope domes in the foreground. He wrote:

Absolutely insane airglow from last night. Yes, what you see on this image are not clouds! That yellow/orangish light comes from the upper atmosphere. I couldn’t believe what I saw on the screen of my camera when I took the first image. It seems the atmosphere is pretty active now and it allows us to witness some incredible views. The Milky Way at parts was barely visible. I hope you’ll enjoy the view!

Thanks, Yuri!
