NASA’s New Horizons spacecraft captured this high-resolution enhanced color view of Pluto on July 14, 2015.

Meet the authors of a new tell-all book that reveals the incredible story behind the little spacecraft that was the first to explore Pluto.

He's best known for having killed Pluto, but astronomer Mike Brown may have found a replacement planet in the outer reaches of our solar system and it forms the basis of a new Adler Planetarium show.

A new baseball statistic that could help the Chicago Cubs win, a new tool that could revolutionize the surgical removal of cancerous tumors and new images of Pluto and its largest moon, Charon. Museum of Science and Industry director of science and integrated strategies Rabiah Mayas joins us with these stories and more.

Pluto finally got a visitor from Earth, 85 years after the dwarf planet’s discovery. Completing a nine-year, 3-billion-mile voyage, NASA's New Horizons spacecraft reached the former ninth planet of our solar system on Tuesday. We'll discuss the milestone flyby with astronomers from the Adler Planetarium.

Caltech Astrophysicist Mike Brown was one of the scientists who, in 2006, led the successful crusade to get the former planet Pluto downgraded to the status of dwarf planet. He joins us to discuss what he's found far, far away in our solar system.
