The Sky At Night is the longest running television programme in the UK, as well as being the longest running astronomy program in the world.

In its 50+ years on air (666 editions to date), host Patrick Moore has covered and continues to cover all aspects of astronomy of interest to the amateur astronomer.

He has only missed presenting one edition of the program in all that time, when he came down with a severe case of food poisoning a few years ago.
