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.
