As the moon snuck in front of the sun during Monday's total solar eclipse, a NASA photographer captured a once-in-a-lifetime sight. 


Joel Kowsky , one of the space agency's photo editors, was in Banner, Wyoming, to watch the solar eclipse when he photographed the International Space Station zooming in front of a crescent sun. Below is a video Kowsky recorded using a high-speed camera that recorded 1,500 frames per second.  He also photographed the ISS with a standard camera



Such high-speed recording is necessary because the ISS is roughly the size of a football field, orbits Earth from 250 miles up, and moves at a speed of 17,500 miles per hour. 


To capture such a fast-moving object from the right angle not only requires months or years of planning , but also a lot of luck.
