Watch Stephen Colbert and Neil deGrasse Tysons Pluto Debate


Stephen Colbert has been keeping himself sharp in the interim between The Colbert Report and The Late Show With Stephen Colbert with his funny, topical run of videos recently. For his latest, he expressed his excitement about NASAs New Horizons spacecraft reaching Pluto and debated with astrophysicist and Pluto detractor Neil deGrasse Tyson about how awesome the dwarf planet actually is.

After almost a century of near-total mystery, we finally know what Pluto looks like: a malted milk ball left in the rain 4.7 billion miles from the sun, the host said early in the clip. The bit was filmed in a cubicle made to look like a fake spacecraft, complete with Tang and printed images of ornate buttonsand knobs.

Colbert went on to gush over the process of getting the photos from New Horizons and the heart-shaped mark on the planet before having the camera pan to Tyson. After joking about Plutos girlfriend (and moon) Charon, Tyson went on to explain that he wishes Pluto were a bit bigger before confidently stating that Pluto has gotten smaller every decade since its discovery in 1930. Dramatically, Colbert pulled out his phone to show Tyson that the spacecraft pictures actually show that the planet is 20 to 30 kilometers bigger than previously expected. Did I just fact check Neil Ill just free ball this one Tyson? he adds as the astrophysicist laughs his mistake off.

The pair continued to playfully debate Plutos merit, with Tyson staunchly refusing to consider it anything more than a dwarf planet. Colbert also used the conversation as a way of parsing more facts about what the latest planetary discoveries mean, even quoting noted astrophysicist Elton Johns Rocket Man before an inquiry about the possibility of life existing on Pluto. Still, even a Klondike Bar couldnt get Tyson to switch sides, though he did slightly concede in noting that Earth would be considered a dwarf planet if we lived on Jupiter.
