  Dr. Neil deGrasse Tyson is director of the Hayden Planetarium, hosts Cosmos: A Spacetime Odyssey and is the former host of NOVA ScienceNOW on PBS. On April 24 he returns to Proctors with an all-new show: "The Cosmic Perspective."

There is no view of the world as emotionally potent as the one granted by a cosmic perspective. It's one that sees Earth as a planet in a vast empty universe. It profoundly influences what we think and feel about science, culture, politics, and life itself.

Space is hot. Yes, I do in fact know that outer space is icy cold… but here on planet earth, shows about the planets and exploration of the universe are turning some astrophysicists into rock stars. Well now there’s one who would rather be a star in interpretive dance. Today on the Best of Our Knowledge, we’ll talk to an astrophysicist who is putting together a multimedia presentation that’s out of this world.

Then we’ll hear about a unique program in Massachusetts that is helping high school students get a good start to the day.

Have the natural laws that govern the cosmos ever changed?

Dr. Jeremy Mould, professor of astrophysics and supercomputers at the Swinburne University of Technology, observes that gravity has remained unchanged for billions of years.

What is left after a star explodes and dies? The answer is a neutron star.

Dr. Victoria Kaspi, professor of astrophysics and cosmology at McGill University, is piecing together the structure of a specific type of neutron star called a magnetar.
