This has been mentioned before on this newsgroup but just in case you
forget - it's on tonight.

Its good to see this kind of material given such prominence on the BBC.
Its
been too long. They've had some superb documentaries and science
programmes
on BBC2 and BBC4 over the last few months.

I've always been interested in space, science, technology and their
impacts
upon our lives. These programmes are helping to fill gaps in my
knowledge.

Enjoyed the show last week about the moon. I realise many people ask
about
viewing the moon landers but I'm sure I read of some plans to test
optical
systems by imaging the craft from lunar orbit. Did I imagine that or is
it
still on the cards?


You didn't imagine it - it's apparently part of the scientific mission
(i.e. not just PR shots :-) of the Lunar Reconnaissance Orbiter mission
http://science.nasa.gov/headlines/y2005/11jul_lroc.htm

I thought it was a highly entertaining evening, and "The Sky at Night"
really whetted my appetite for the solar eclipse this month!
But is the speed of light really "less than 1 millimetre per second" in
the core of the Sun? I thought the photons just did a very long random
walk on their way out.
Keyword missing in the statement. 'Effective'.
The actual speed is reduced by the enviroment, but not by this much!...

Best Wishes
