How to Bookmark APOD

Link to our main NASA site: http://apod.nasa.gov/ which will direct you to http://apod.nasa.gov/apod/astropix.html. This main site is the first to update and the most likely to be up-to-date. (Here is an automatic backgrounder program for Windows XP that accesses the main site.)

Alternatively, link to one of our mirror sites:

These addresses will bring you the most recent available Astronomy Picture of the Day (APOD). In Netscape, click on "Bookmarks", then "Add Bookmark." If the date displayed is anything other than today's date, hit "Reload", SHIFT "Reload", or "Refresh" on your browser. To see past APODs, click on "Archive" near the bottom of each page. To navigate to the previous day's picture, click on the less than [ < ] symbol near the bottom left of each page. If it is available, you can also navigate to the next day's picture by clicking on the greater than [ > ] symbol near the bottom right of each page.

New Media APOD-Related Content

We are aware of several "new media" venues that carry APOD-related content. Most of these are done on a volunteer basis and are not supported directly by APOD or NASA. In sum, APOD considers these to be mirror sites that make classic APOD content readable not in a different language -- but with different technology. Some of these venues might partially support themselves by carrying advertising next to uncopyrighted images. This seems OK to us and we have therfore given them permission to use APOD text as it seems to give a broader reach to APOD's educational mission. Please note that neither APOD nor NASA receives any part of any advertising revenue.

    Astronomy Picture of the Day (APOD) is originated, written, coordinated, and edited since 1995 by Robert Nemiroff and Jerry Bonnell. The APOD archive contains the largest collection of annotated astronomical images on the internet.

    In real life, Bob and Jerry are two professional astronomers who spend most of their time researching the universe. Bob is a professor at Michigan Technological University in Houghton, Michigan, USA, while Jerry is a scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland USA. They are two married, mild and lazy guys who might appear relatively normal to an unsuspecting guest. Together, they have found new and unusual ways of annoying people such as staging astronomical debates. Most people are surprised to learn that they have developed the perfect random number generator.

    APOD is proud to acknowledge that it received several accolades during its short existence, including a Scientific American 2001 Sci/Tech Web award.

    Do you enjoy APOD? Do you have a picture that would make a good APOD? If so, we would enjoy hearing from you. Images are most often submitted by email or by posting to a web site. Please see this page or write to Robert Nemiroff at nemiroff at mtu dot edu or Jerry Bonnell at bonnell@grossc.gsfc.nasa.gov regarding image submissions. Please note that by submitting your image to APOD, you are consenting for your image to be used on APOD in all of its forms unless you explicitly note otherwise. These include mirror sites, foreign language mirror sites, and direct APOD derivative products including thumbnail feeds on Facebook and Google+ under names having to do with "Sky" and "APOD". We do recommend that you include a small copyright notice in a corner of your submitted images.

    Note for image submissions: The APOD pages are collected annually on a CD-ROM, which is distributed free of charge to educators and the general public. If you would like your image to be considered for an APOD but do not want your image included in this CD-ROM collection, please let us know.

    Thank you for sharing the APOD experience! We genuinely hope you have had an entertaining and educational few moments with us.
