NASA satellite captures moment Earth eclipses the sun

NASA's sun-observing spacecraft has captured colorful images of the moment the earth blocked its view of the sun. In a short animation posted on Tuesday, the Solar Dynamics Observatory's (SDO) view of a purple-colored sun is interrupted as Earth completely covers its surface. The sun isn't actually purple, but it looks that color because the images were taken in a wavelength of extreme ultraviolet light. This kind of ultraviolet light is a type that's usually invisible to the human eye, so NASA noted that it's been colorized in purple. Stunning footage from NASA's Solar Dynamics Observatory captures when the earth completely covers its view of the sun.
