Rosetta spacecraft arrived at Comet 67P/Churyumov-Gerasimenko on Aug. 6, 2014. Rosetta is named for the Rosetta Stone, a block of black basalt that was inscribed with a royal decree in three languages — Egyptian hieroglyphics, Egyptian Demotic and Greek. The spacecraft's robotic lander is called Philae, named after a similarly inscribed obelisk found on an island in the Nile River. Philae will land on the comet in November- the first ever controlled landing on a comet.

As ESA's Rosetta spacecraft prepared to dispatch its Philae lander to the surface of Comet 67P/Churyumov-Gerasimenko, a set of instruments on Rosetta picked up a mysterious "song" from the comet. Neutral particles released into space by the comet may becoming electrically charged or ionized. The mechanism behind the oscillations remains a mystery
