MIT 27 Sep 2017, 18:00 UTC The following news article is adapted from a press release issued by the Laser Interferometer Gravitational-wave Observatory (LIGO) Laboratory, in partnership with the LIGO Scientific Collaboration and Virgo Collaboration. LIGO is funded by the National Science Foundation (NSF) and operated by MIT and Caltech, which conceived and built the project. The LIGO Scientific Collaboration and the Virgo collaboration report the first joint detection of gravitational waves with both the LIGO and Virgo detectors. This is the fourth announced detection of a binary black hole system and the first significant gravitational-wave signal recorded by the Virgo detector, and highlights the scientific potential of a three-detector network of gravitational-wave detectors. The three-detector observation was made on Aug. 14 at 10:30:43 UTC. The two Laser Interferometer Gravitational-wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington, and funded by the National Science Foundation (NSF), and the Virgo detector, located near Pisa, Italy, detected a transient gravitational-wave signal produced by the coalescence of two stellar mass black holes. A paper about the event, known as GW170814, has been accepted for publication in the journal Physical Review Letters. The detected gravitational waves — ripples in space and time — were emitted during the final ...
NASA's Jet Propulsion Laboratory News and Features 27 Sep 2017, 16:52 UTC Ten years ago, NASA's Dawn spacecraft set sail for the two most massive bodies in the asteroid belt between Mars and Jupiter: giant asteroid Vesta and dwarf planet Ceres. The mission was designed to deliver new knowledge about these small but intricate worlds, which hold clues to the formation of planets in our solar system.
