ANITA Antarctic Impulsive Transient Antenna The ANITA instrument is a radio telescope to detect ultra-high energy cosmic-ray neutrinos from a scientific balloon flying over the continent of Antarctica. ANITA is the first NASA observatory for neutrinos. Detects ultra-high energy neutrinos through observing coherent radio emission from the cascade of particles produced in a high-energy particle interaction. Need a radio transparent medium such as ice for the interaction to occur in - and lots of it since these interactions are rare. Dec 2006 – Jan 2007 the ANITA instrument flew over Antarctica - the location of some of the most pure ice in the world as well as one of the most radio quiet spots on earth.
