The stars are ringing like the strings of mandolins, guitars and bass fiddles say astronomers studying the unprecedented reams of data on thousands of stars pouring in from the new Kepler spacecraft. The themes of all that celestial music are familiar enough: loneliness, glory days and the passage of close friends (translated into astronomese: distance, age and exoplanets).
Take the loud, low crooning of those bluesy red giant stars.
"Kepler is literally listening to thousands of red giant musicians in the sky," said Daniel Huber a graduate researcher in astronomy at the University of Sydney, Australia. Huber spoke at a Tuesday press teleconference by the Kepler Asteroseismic Science Consortium at Aarhus University in Denmark.
Red giants are stars entering the late stages of their lives, when they begin to run out of fuel and start swelling.
