I still think this is one of the most exciting places to visit. Jodrell Bank in Cheshire. It is a massive structure whuch us dedicated to looking at the universe in the radio part of the spectrum. It has been responsible for some of the mist important radio astronomy since it was built in the mud twentieth century.
The telescope was built by the university of Manchester and is out in the countryside because it was away from the radio frequency noise of cities in the North and Midlands of England.
The complex has a beautiful visitor centre, cafe, lecture halls and science space full of fascinating information about the dolar system, our galaxy, and into the far out reaches of the universe. There is also an amazing arbouretum full of specimen trees and a map of the planet’s. I don’t have all the details or the prices for entry, but if you are ever in the area its worth a visit.
