I'm qp4. I've been reading the wikipedia for several years now, but only recently signed up, as the place has grown a huge amount and many articles need clean up. I'm still trying to get a handle on how to use the interface though, so I've not been very active.--Qp4 22:01, 17 October 2006 (UTC)

IceCube Neutrino Observatory
The IceCube Neutrino Observatory is a neutrino detector constructed at the Amundsen–Scott South Pole Station in Antarctica. Similar to its predecessor, the Antarctic Muon And Neutrino Detector Array, IceCube consists of spherical optical sensors called Digital Optical Modules, each with a photomultiplier tube, located under the Antarctic ice and distributed over a cubic kilometre. The project is a recognized CERN experiment and construction was completed in 2010. This photograph shows the exterior of the IceCube building in 2023.Photograph credit: Christopher Michel
