How Antarctic ice acts as a telescope for ghost particles

Ghost Particles Are Exposing Hidden Black Holes. They Just Won a Nobel Prize. · 19:06 · Video: PBS Space Time · Watch at the source

In short: The 2026 Nobel Prize in Physics recognized the technology used to detect neutrinos—elusive particles that can travel through almost anything. This video explores how scientists turn massive blocks of ice into cosmic detectors.

Francis Halzen received the Nobel Prize for his role in developing IceCube, a detector located in the Antarctic. By using a cubic kilometer of ice as a medium, researchers can capture neutrinos to trace cosmic rays back to their sources.

These "ghost particles" are uniquely capable of revealing hidden supermassive black holes and providing a new method for observing the universe's most distant phenomena.
