The marvelous Maria Popova recently brought two stories on space and sound to our attention. First, NASA informed the citizens of earth today that Voyager has made it to interstellar space (about 12 billion miles away), and sent us this sound of an explosion on the sun.

Then, a video tutorial on how to fold space-time featuring a wooden bowl, Möbius strip, backwards Bach, and the Music Box kit from our 2012 Holiday Gift Guide.
