Best Planetary Destruction in a Movie

A fan wants to know what was the most scientifically accurate destruction of a planet on the big screen. To answer this Cosmic Query, astrophysicist Neil deGrasse Tyson and comic co-host Eugene Mirman compare three of the most spectacular cinematic obliterations: the destruction of Alderaan by the Death Star in “Star Wars IV — A New Hope,” the destruction of Vulcan by a planet-eating black hole created from “red matter” in J.J. Abrams’ “Star Trek” reboot, and the destruction of Krypton due to over-mining from the Superman reboot, “Man of Steel.” And the winner is…

Neil deGrasse Tyson on Calculating the Distance of a Quasar

If a quasar is billions of light years away, how can we calculate that distance when the light takes billions of years to reach us? Astrophysicist Neil deGrasse Tyson explains why we can see events that took place before Earth even existed in this StarTalk Radio “Behind the Scenes” Cosmic Queries video with comic co-host Eugene Mirman.

Death in Space

How accurate was the depiction of death in space in the movie, “Gravity”? Does NASA have protocols if an astronaut dies in space?

Mike Massimino on Medical Emergencies on the ISS

If there were a medical emergency on the International Space Station, is there a doctor aboard? (Or a veterinarian?) And if it were really bad, how quickly could the injured astronaut get back to Earth aboard a Soyuz “life boat?” Would you believe us if we said 2 hours or less? How about if NASA astronaut and veteran of 2 space shuttle flights Mike Massimino said it? Join guest host Astro Mike and comic co-host Chuck Nice as they answer a fan’s Cosmic Query in this exclusive YouTube video.

Mike Massimino: What George Clooney Did Wrong in Gravity

Spoiler Alert: Did George Clooney really have sacrifice himself to save Sandra Bullock in the Academy Award nominated movie “Gravity”? Not according to guest host and 2-time Space Shuttle astronaut “Astro Mike” Massimino, who tells co-host Chuck Nice what he would have done differently, and why. In addition to discussing the “two-body problem” of tethered astronauts in space, Mike explains how an experienced astronaut would “go down swinging” rather than just giving up — no matter what Hollywood thinks.

Why Nobody Can Hear You Scream in Space

A fan asks how come we can hear noise and explosions in space in the movie, “Gravity,” since sound isn’t supposed to travel in a vacuum. Luckily, guest astronaut Mike Massimino is in the studio to explain why “Gravity” got it wrong… from personal experience. 2-time space shuttle astronaut Astro Mike is sitting in for Neil deGrasse Tyson in this clip, but comic co-host Chuck Nice is on hand to make sure the mission goes according to plan.
