Have you ever listened to a star—one with real gravity? Drop by this site from the Jodrell Bank Observatory to hear the sounds of a pulsar, a rapidly spinning neutron star that gives off a signal as regular as a metronome. Located near the British city of Manchester, Jodrell Bank has been a mecca for astronomers since the 1940s. Besides reading about the history of the facility and current research, site visitors can check out tutorials on topics such as pulsars. Or read up on supernovas and the use of gravitational lensing—the bending of light from distant objects by the gravity of closer objects—to gauge the expansion of the universe.
