Lucy Hunter caught this amazing photo of the Northern Lights over Narada Lake in the Sleeping Bear Dunes National Lakeshore last month, and my favorite photo blog, NASA’s Earth Science Picture of the Day, just featured it! Lucy & blog-runner Jim Foster write:
This gorgeous aurora was captured over the Sleeping Bear Dunes National Lakeshore of northern Michigan, earlier this spring. The camera is facing north. The feeble light produced by the purple-colored curtains and the horizon-hugging greenish glow was sufficient to cast shadows on the lake in the foreground.
Auroras’ colors vary because the Earth’s atmosphere is composed of many compounds, particularly nitrogen and oxygen, which when excited by charged particles streaming from the Sun, give off light. Silhouettes of worn out trees nicely accent this scene. Photo taken on May 5, 2018.
