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 IceCube! 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 IceCube was a titanic endeavor driven by our human passion for discovery.

The beauty of a starlit sky conceals the violent forces at work within our universe. From the upheaval of a giant star that explodes to release its material into space, to a future encounter between the Earth and a large asteroid that is too close for comfort, we will witness the forces that hold the universe together and occasionally try to rip it apart. Narrated by Patrick Stewart of "Star Trek: The Next Generation" and the X-Menfilms.

Read More"Astronaut," the latest immersive planetarium show to be created by the National Space Centre, takes you from Earth into space... and beyond. Experience a rocket launch from inside the body of an astronaut. Explore the amazing worlds of inner and outer space, from floating around the International Space Station to maneuvering through microscopic regions of the human body. Discover the perils that lurk in space as we subject 'Chad', our test astronaut, to everything that space has to throw at him. 

Presented in stunning high definition 360-degree full-dome video and explosive surround sound, Astronaut is an experience like nothing on Earth.

Recognizing Robert H.N. Ho '56

Robert H.N. Ho '56 (left) at the center dedication, accepting an image of the Ho building.
In recognition of a special gift by Robert H.N. Ho '56 in memory of his grandfather Sir Robert Ho Tung. Knighted twice by King George V and Queen Elizabeth II, Sir Robert Ho Tung was active as a businessman and philanthropist in the British Crown Colony of Hong Kong.

At the September 15, 2007 dedication ceremony, Mr. Ho quoted a Chinese proverb: "huh shwei, suh yuan"-"Drink water: consider source."

May those who discover new frontiers in this laboratory consider how they can model Sir Robert Ho Tung and Robert H.N. Ho's inspiring words.
