Rosetta-Alice Spectrograph Maps A Comet's Surface For First Time

NASA's Alice ultraviolet, or UV, spectrograph aboard the European Space Agency's Rosetta comet orbiter has obtained the first "far ultraviolet spectra" of a cometary surface, scientists announced Thursday. Rosetta, which is in orbit around the comet called 67P/Churyumov-Gerasimenko, is the first spacecraft to study a comet in such close proximity.
