Each year, scientists launch balloons with high-tech equipment from the McMurdo Station for this purpose. Physicists from the National Research Nuclear University MEPhI are conducting the Antarctic Impulsive Transient Antenna (ANITA) experiment to search for ultra-high-energy (UHE) cosmic neutrinos together with the NASA Astrobiology Institute at the University of Hawaii.

There are no radio-emission sources in the Antarctic, and this allows scientists to find traces of neutrinos penetrating the thick ice layers. For this purpose, physicists use powerful radio antennas that resemble ordinary radio telescopes in terms of their operation.

The entire Antarctic surface acts as a natural neutrino detector that can function without a break.

An ANITA antenna is a formidable array of radio transceivers about seven meters high and weighing about one metric ton. The balloon hoists the antenna to an altitude of 37 kilometers where it registers ultra-high-energy neutrinos.

Unlike space satellites, modern balloons can be launched many times, making it possible to cut the research costs.

The balloon makes it possible to see virtually the entire continent and to record events taking place hundreds of kilometers away from it.

The Antarctic research program was launched 100 years ago. Next to the McMurdo Station stands the shack of Robert Scott, who co-discovered the southernmost and coldest continent on Earth. Built in 1902, it survives to this day.

Scientists, researchers and geologists from 12 countries are so far the only people coming to the Antarctic in order to study the continent and to unlock the mysteries of the universe.
