Deep in the ice at the heart of Antarctica, the biggest and strangest detector in the world waits for mysterious messengers from the cosmos. Scientists are using tiny and elusive particles called neutrinos to explore the insides of stars and galaxies. These ghostly neutrinos give us an exclusive look into exploding stars and black holes. In this new program, we see stunning views of the most extreme places in our universe. The galaxies around us, the Earth, and the Sun are the prelude to a thrilling journey inside the detector, looking for traces of neutrinos from when they collide with atoms in the ice. From one of the most remote locations on Earth to the unexplored regions of the cosmos, Chasing the Ghost Particle: From the South Pole to the Edge of the Universe takes you on a journey you will never forget.

The stars themselves are featured in our last program as we look at the life cycles of the stars.  This program is narrated in part by Nichelle Nichols, the actress who played Lt.
