Tycho Project
From Tardis Wiki, the free Doctor Who reference
The Tycho Project was a network of radio telescopes around the world, searching for friendly life in outer space. Amongst it's targets was Rigel Beta Five. As of 2009, the Tycho project was still unsuccessful.
One of it's telescopes, located in Goblin's Copse in the United Kingdom, was converted from a Cold War listening station. This station was at one point taken over by a Sontaran soldier, the lone survivor of the Tenth Sontaran Battle Fleet attempted invasion of Earth. (SJA:The Last Sontaran)
