DAILY CAPTIVATING COSMIC IMAGES WITH EXPERT INSIGHT
About
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. APOD occasionally repeats images, in part to inform new readers the best of the older images. APOD occasionally reuses APOD text, in part to avoid restating a point that has been well-stated on APOD before.
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.
