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.

Alternatively, link to one of our mirror sites:

These addresses will bring you the most recent available Astronomy Picture of the Day (APOD). Some people find it convenient to bookmark the main APOD page and to refresh it to see the latest APOD. Alternatively, to see past APODs, please 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. 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.

    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.

    APOD in general and the APOD site served from NASA specifically places links solely on information content and does not endorse any commercial product nor guarantee claims or sales made on any linked pages.

    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.
