This weekend the BBC Programme "The Sky at Night" celebrates 50 years of continuous broadcasting. With every programme but one (don't mention goose eggs!) hosted by Sir Patrick Moore, this programme has broken just about every record for longevity and is a cherished part of life for more than one generation of amateur astronomers.
This edition promises to be something rather special if Chris Lintott's blog is anything to go by (And don't forget you can meet Chris at our special Keswick Mountain Festival event on 19th May - more details to follow)
The Sky at Night is on BBC 1 at the atypically early time of 11:30pm Sunday evening and again on BBC4 at 8:30pm on Monday.
