Some background. Jodrell Bank in Cheshire UK is the site of a large fully steerable radio telescope, named after Bernard Lovell who conceived it in the years after WWII and oversaw its construction. Commissioned in 1957 it is still the largest single steerable disk in the world. One of its first tasks was to track the signal from Sputnik 1, and indeed its launch rocket (it was an ICBM rocket, and Jodrell Bank was the only instrument in the world able to track it.) Owned by Manchester University, it still operates as a scientific instrument, both in its own right and as a part of various interferometry experiments.
It is hard to appreciate its scale, the arrow points a a chap doing a bit of weeding (you may need Lytebox!)
The main dish has a magic all of its own:
And for any engineers out there, the gearing at the top of each tower was recycled from the 15" gun turrets on the British battleships Royal Sovereign and Revenge!
And now I'm over to Nik to see what they look like in B&W.
Cheers,
