LIGO and Virgo Announce Four New Gravitational-Wave Detections

The figure on the left shows the localizations of the various gravitational-wave detections in the sky. The triple detections are labelled as HLV, from the initials of the three interferometers (LIGO-Hanford, LIGO-Livingston and Virgo) that observed the signals. The reduced areas of the triple events demonstrate the capabilities of the global gravitational-wave network.

On Saturday 1st December 2018, scientists attending the Gravitational Wave Physics and Astronomy Workshop in College Park, Maryland, presented new results from searches for coalescing cosmic objects, such as pairs of black holes and pairs of neutron stars, by the LIGO and Virgo detectors. The LIGO and Virgo interferometers have now confidently detected gravitational waves from a total of 10 […]

NASA’s InSight Is One Day Away from Mars

  In just over 24 hours, NASA’s InSight spacecraft will complete its seven-month journey to Mars. It will have cruised 301,223,981 miles (484,773,006 km) at a top speed of 6,200 mph (10,000 kph). Engineers at NASA’s Jet Propulsion Laboratory in Pasadena, California, which leads the mission, are preparing for the spacecraft to enter the Martian atmosphere, descend with a parachute […]

InSight Spacecraft on Course for Mars Touchdown

  NASA’s Mars Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) spacecraft is on track for a soft touchdown on the surface of the Red Planet on Nov. 26, the Monday after Thanksgiving. But it’s not going to be a relaxing weekend of turkey leftovers, football and shopping for the InSight mission team. Engineers will be keeping a […]
