In 2011, a massive "space telescope" was installed beneath the Antarctic snowfields.
It is the "Ice Cube," with sides measuring one kilometer in height.
Over 5,000 optical sensors were embedded into this colossal block of ice, large enough to swallow dozens of New York skyscrapers with room to spare.
The purpose is to observe neutrinos—"ghost particles" that have no electric charge and pass through matter without resistance.
The person who first proposed this Don Quixote-like concept of turning the Antarctic glaciers into a laboratory is Frances Halzen, a Belgian professor at the University of Wisconsin-Madison and this year's Nobel Prize winner in Physics.
[Frances Halzen / Nobel Prize Winner in Physics: People thought it was a good idea, but they believed it would not actually succeed. We decided to just go ahead and see when we would run into failure. In the end, we didn't fail, though.]
Neutrons are the second most abundant particles in the universe, after photons, and trillions of them pass through our bodies every second.
Although they do not react with matter, they collide with atomic nuclei extremely rarely; sensors inside the ice capture the blue light emitted by the particles that are ejected during these collisions.
In 2017, they even detected neutrinos estimated to have traveled from near a black hole billions of light-years away.
Astronomy, which previously focused on observing light, has gained a "new eye."
[Göran Johansson / Nobel Prize in Physics Committee Member: Neutrinos tell us about dynamic events occurring in the universe, such as cosmic rays, where ultra-high-energy particles are generated.]
'IceCube' has evolved into an international collaborative research project involving over 450 researchers from 14 countries, including South Korea.
Moving forward, plans are underway to launch a second-generation IceCube that will increase the scale of observation eightfold.
