Since I was a kid, I’ve always loved the thought of space and the vast empty spaces between planets and galaxies.
This image shows a map of our Universe with galaxies colour coded to indicate their red shift. The red shift is a manifestation of the Doppler Effect- when a car moves away from you, if you hear its horn, the frequency of the horn drops as it gets further away. The horn’s frequency hasn’t actually changed, just that the sound has further to travel and so sounds lower. The light from an object moving away lowers frequency towards the red end of the spectrum; that’s the red shift.

Reopening in November 2007, London Transport museum have revamped their website and added 5,000 of their classic posters and 700 original art works online in various collections.
The posters are nicely organised in various themes- eg Sport, Beyond the City, Events, Entertainments, Open Air London, London’s Transport System etc or you can browse the artist by A-Z. It’s well organised and there is some fascinating stuff. Very well worth a visit (both the website and the museum) and you can buy copies of posters from the website as well.
