Electronic musician John Boswell has just released the 12th installment in his "Symphony of Science" series. Onward to the Edge celebrates the adventure of space exploration and features the auto-tuned voices of astrophysicist Neil deGrasse Tyson, particle physicist Brian Cox and planetary scientist Carolyn Porco. It's a mashup of material from four sources: Tyson's My Favorite Universe video course, Cox's BBC series Wonders of the Solar System, a TED talk by Porco and scenes from National Geographic's A Traveler's Guide to the Planets.
The "Symphony of Science" grew out of Boswell's 2009 video, A Glorious Dawn, which stitches together scenes from Carl Sagan's Cosmos and Stephen Hawking's Universe and has been viewed over six million times on YouTube. You can download a free digital album of all 12 songs from the series, along with a bonus track, here. H/T BoingBoing
