Astronomy Picture of the Day (APOD) is a website provided by NASA and Michigan Technological University (MTU). According to the website, "Each day a different image or photograph of our universe is featured, along with a brief 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. However, the pictures and descriptions are often related 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 photographs, images taken at other wavelengths and displayed with false colors, video footage, animations or artist’s conceptions. Past images are stored in the APOD Archive, with the first image appearing on June 16, 1995. This initiative has received support from NASA, the National Science Foundation, and MTU. The images are sometimes authored by people or organizations outside of NASA, and therefore APOD images are often copyrighted, unlike many other NASA image galleries.
When APOD began it received only 14 pages views on its first day. As of 2012 it is estimated that there have been over 1 billion image views. APOD is also translated into 21 languages daily.
APOD was presented at a meeting of the American Astronomical Society in 1996. Its practice of using hypertext was analyzed in a paper in 2000. It received a Scientific American Sci/Tech Web Award in 2001. In 2002, the website was featured in an interview with Nemiroff on CNN Saturday Morning News. In 2003, the two authors published a book titled The Universe: 365 Days from Harry N. Abrams, which is a collection of the best images from APOD as a hardcover "coffee table" style book. APOD was the Featured Collection in the November 2004 issue of D-Lib Magazine.
Famous quotes containing the words day, astronomy and/or picture:
“The day was ending at it was the hour of which I do not want to speak, the hour without a name, when the sounds of evening ascended from all the floors of the prison in a procession of silence.”
—Albert Camus (19131960)
“Awareness of the stars and their light pervades the Koran, which reflects the brightness of the heavenly bodies in many verses. The blossoming of mathematics and astronomy was a natural consequence of this awareness. Understanding the cosmos and the movements of the stars means understanding the marvels created by Allah. There would be no persecuted Galileo in Islam, because Islam, unlike Christianity, did not force people to believe in a fixed heaven.”
—Fatima Mernissi, Moroccan sociologist. Islam and Democracy, ch. 9, Addison-Wesley Publishing Co. (Trans. 1992)
“With wonderful art he grinds into paint for his picture all his moods and experiences, so that all his forces may be brought to the encounter. Apparently writing without a particular design or responsibility, setting down his soliloquies from time to time, taking advantage of all his humors, when at length the hour comes to declare himself, he puts down in plain English, without quotation marks, what he, Thomas Carlyle, is ready to defend in the face of the world.”
—Henry David Thoreau (18171862)
