The Sky at Night – Grand Collision

Sir Patrick Moore looks ahead to 2 billion years when the Milky Way will collide with another galaxy, Andromeda, an event which will destroy stars and planets but will eventually create new stars, solar systems and planets.

Dr Chris Lintott steps outside to look at Andromeda, easily visible in the night sky using binoculars. It is still 2.5 million light years away, but getting closer by the day.

Shown on BBC4 @ 7.30pm on Sunday 4th November 2007
