Just heard about it this lunchtime.
One of my absolute idols of science broadcasting. His TV appearances and his show "The Sky At Night," one of the longest-running TV shows in the world, helped continue my interest in amateur astronomy as a child, and still continued to do so today - I saw this month's (extended) edition only last night. I owned a number of his books on astronomy and the night sky, including one called "Astronomy for the Under-Tens" which I still have on my bookshelf.
He was also a terrific xylophonist, and was always a delight on the TV.
RIP, Sir Patrick.
