Josh, Addie and Tracy welcome Jürgen Blum from the University of Braunschweig to discuss the exciting landing of the ESA Philae probe on the comet 67/P Churyomov-Gerasimenko. Philae, carried to the comet by the ESA probe Rosetta, is the first spacecraft to land on a comet. In addition to revealing the secrets of the universe, it will also tell us whether the comet depiction in the classic film “Deep Impact” was merely great or the greatest ever.
This week’s episode is dedicated to the late Tom Magliozzi, one of the Car Talk brothers, whose infectious laughter livened up the airwaves for 25 years. In his honor, while discussing the discovery of “ghost stars” in images from the Hubble Space Telescope, we laugh way too much at Josh’s skivvies and Tracy’s home village of New Jersey.
