BBC London has published now the second episode of "Richard Hammond's Invisible Worlds" on iPlayer and also on BBC HD for viewing.
Here the link to the video only viewable in the UK unfortunately. If you are on a server in the UK and you're away from home, you could of course use your Virtual Private Network (VPN) to watch, so you won't miss it...
This is the link to the HDTV version of it.
That second episode leads us to the world of ultraviolet light (where I have contributed), infrared and to the stars.
Stay tuned, more will follow on that fascinating subject...
