Closure of Great Equatorial Dome and Time for Navy Gallery

The Great Equatorial Dome and the Time for Navy Gallery will be closed between 11:30am and 3.45pm on Tuesdays, Wednesdays and Thursdays from 25 July to 24 August for Daytime sky watch sessions 

Planetarium closures

Visiting the planetarium? Our planetarium is open daily, 10am-5pm. It is closed for maintenance on the first Tuesday of every month from September 2017. See what's on and choose your next space adventure

Don't forget that our clocks will return to Greenwich Mean Time this Sunday morning (the 28th of October).
This means that we have to turn our clocks backwards one hour... but we do get an extra hour in bed on Sunday morning to make it all worthwhile!
