The Milky Way shines in the Yellowstone Grand Canyon in this stunning image.
Astrophotographer A. Garrett Evans took this image in June 26 from Lower Falls in the Yellowstone Grand Canyon and shared it this month with Space.com.
"After arriving at the location around 2 a.m. I had to wait for the moon to set," Evans wrote in an email. "Once it did the sky was amazing,the Milky Way was so bright and the green air glow the camera was capturing was incredible." [See more amazing Milky Way photos by stargazers]
After taking the image, Evans had a surprise encounter.
"On the path just before the parking area we and I bumped into a large bull elk, only about 15 feet away. He was in no hurry so we waited for him to move along so we could get to the car. Bumping into a large animal at night sure gets the blood flowing," he added.
The photo is a blend of two shots, one for the sky and one for the foreground, taken 15 seconds apart. The foreground was shot at ISO 1600, f/2.8, for 346 seconds, and the sky was taken at ISO 8000, f/2.8, for 15 seconds. Both with a Canon 6D, using a Nikon 14-24 mm lens with a Novoflex adapter.

The Milky Way, our own galaxy containing the solar system, is a barred spiral galaxy with roughly 400 billion stars. The stars, along with gas and dust, appear like a band of light in the sky from Earth. The galaxy stretches between 100,000 to 120,000 light-years in diameter.
