Chasing the Ghost Particle

Deep in the ice at the heart of Antarctica, the biggest and strangest detector in the world waits for mysterious messengers from the cosmos. The detector is Ice Cube! The messengers are neutrinos, ghostly particles that give us tantalizing looks into world of exploding stars and black holes. This show tells the incredible story of how an international team of scientists and engineers transformed one billion tons of Antarctic ice into a telescope. Building Ice Cube was a titanic endeavor driven by our human passion for discovery. Witness stunning views of the South Pole, captivating animations of the Ice Cube detectors capturing a neutrino collision-and eye-catching views of the cosmos. Chasing the Ghost Particle: From the South Pole to the Edge of the Universe will take you on a journey you will never forget. This research won the 2026 Nobel Prize in Phyics.

Two Small Pieces of Glass

While attending a local star party, two teenage students learn how the telescope has helped us understand our place in space and how telescopes continue to expand our understanding of the Universe.
