The last Digital Optical Moduel in the IceCube array descends into the ice just before 6pm on the 18th of December, South Pole time
After five years of construction, an international team has put the finishing touches on the University of Wisconsin’s IceCube Neutrino Observatory. Located in Antarctica, the observatory is looking specifically for high-energy neutrinos, which are created in violent cosmic events such as super novae and gamma ray bursts. As neutrinos collide with water molecules in the pitch black, ultra-clear ice, a blue flash of light results, which is detected by the sensors. Ever since neutrinos were discovered in 1956, scientists have hoped to decipher the information these astronomical messengers carry about distant cosmic events and the completion of the observatory marks an important step towards tracing their origins.
