Sir Patrick Moore, a British amateur astronomer who hosted a BBC show on astronomy for over half a century, passed away Sunday at the age of 89. Moore is best known as the host of the BBC TV program "The Sky at Night" starting in 1957, missing only a single episode, due to illness, over the course of more than 50 years. Moore was also an author and active observer, creating maps of the Moon that were reportedly used by NASA during the race to the Moon in the 1960s.
