Two videos to mark the New Horizons probe passing (and snapping) Pluto.

From Periodic Videos, a look at the role of Plutonium.

Plutonium played a key role in the New Horizons mission to Pluto. More Plutonium: https://www.youtube.com/watch?v=89UNPdNtOoE Featuring Professor Martyn Poliakoff.

And some fun chat from the crew at Sixty Symbols (grain of salt recommended).

A mix of views on Pluto and its non-planet status. Astronomers Mike Merrifield and Meghan Gray, and office mate Tony Padilla who is a particle physicist and bit of a stirrer!

And here are some other related videos from the archive.

Demoted as a planet, Pluto is still a fascinating object surrounded in mystery. And it was NOT named after the dog! More films at http://www.sixtysymbols.com/

We're given special access to various plutonium compounds at the National Nuclear Laboratory, in Sellafield. A chance to meet the "Hannibal Lecter of the Periodic Table". With thanks to Mark Sarsfield and Chris Maher... http://www.nnl.co.uk/ In part this video shows how plutonium is extracted from nuclear fuel waste.
