Jim Kingdon heeft ons zojuist aangekondigd :
Don't forget the dish array at Westerbork, see
http://www.astron.nl/p/WSRT2.htm
Also http://en.wikipedia.org/wiki/Green_Bank_Telescope (about 100m,
steerable).
But Arecibo, at 305 m, is much larger than any of these (although it
is only slightly steerable, so you have to wait for your target to
pass over the dish).
Ah, okay... I thought you were talking about a disk array, not about a
single disc.
Anyway, here a google earth web link of Westerbork telescope array
