Astronomy Picture of the Day

Astronomy Picture of the Day (APOD) is a website provided by NASA and Michigan Technological University (MTU). Each day it features a different image of the universe accompanied by an explanation written by a professional astronomer. The photograph does not necessarily correspond to a celestial event on the exact day that it is displayed, and images are sometimes repeated. These often relate to current events in astronomy and space exploration. The text has several hyperlinks to more pictures and websites for more information. The images are either visible spectrum photographs, images taken at non-visible wavelengths and displayed in false color, video footage, animations, artist's conceptions, or micrographs that relate to space or cosmology.
