How to Bookmark or Hotlist APOD

In real life, Bob and Jerry are two professional astronomers who spend most of their time researching the universe. Bob is an assistant 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 otherwise appear normal to an unsuspecting guest. Together, they have found new and unusual ways of annoying their wives such as staging astronomical debates. Most people are surprised to learn that they have developed the perfect random number generator.

APOD was voted NASA Cool Site of the Year for 1995. Thanks!
