Astronomy Picture of the Day: A Web Site Review

NASA runs a web site called Astronomy Picture of the Day (aka APOD), which every day has a different photograph or image that is in some way related to astronomy.

Most of these pictures are of objects in outer space or areas of outer space. These are frequently absolutely astounding, such as this recent image, which is titled "The Busy Center of the Lagoon Nebula." Wow, just wow.

As is acknowledged in the site's FAQ, they do occasionally rerun images (especially when new information about older pictures becomes available on the web). Perhaps the most impressive fact about the site is that it has been running continually since 1995 (as documented by the archive). That has to make it one of the oldest continually updated sites on the web, which is pretty astounding in and of itself.

For anyone with any amount of interest in astronomy or outer space, daily visits to APOD are a must.
