Universal pleasures

Things to do, places

"How big is the universe?" is one of those questions asked by difficult children, drunk people and faceless interrogators in interview nightmares. But fret no more, for the answer to this and other space oddities is to be found in Peterborough. Into Orbit, a new space exhibition at the city's museum, will elucidate the celestially ignorant with activities ranging from a lecture by Helen Sharman, the UK's first astronaut in space (today 2.30pm Key Theatre, 01733 52439), to screenings of the complete series of Star Trek movies. On display are pieces of the moon chipped off by American astronauts, which will be under constant guard to stop them from moonwalking. With a stargazing evening run by the Sawtry Astronomical Society and a gathering of sci-fi writers at the Central Library, Peterborough's the place to get spaced this weekend.

'Into Orbit', City Museum, Peterborough (01733 343329) to 18 Nov
