  2. Taylor and Joel M. Weisberg in 1982 found that the orbit of the pulsar was slowly shrinking over time because of the release of energy in the form of gravitational waves. For discovering the pulsar and showing that it would make possible this particular gravitational wave measurement, Hulse and Taylor were awarded the Nobel Prize in Physics in ...
  3. Jun 28, 2023The collaboration has spent more than 15 years collecting high-precision data from ground-based radio telescopes, looking for these gravitational waves. The discovery complements the first-ever detection of gravitational waves in 2015 by LIGO, the Laser Interferometer Gravitational Observatory. Those signals, at a much shorter wavelength than ...
  4. The collision released massive amounts of energy in a fraction of a second (about 50 times as luminous as all the stars in the visible universe combined) and sent gravitational waves in all directions. On September 14, 2015 those waves reached Earth and were detected by researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO).
  5. In 2015, a collaboration between the U.S.-based Laser Interferometer Gravitational-wave Observatory (LIGO) and the Virgo interferometer in Europe announced the first direct detection of gravitational waves: They were emanating from two black holes - each with a mass about 30 times greater than the Sun - circling one another and merging.
  6. detect the presence of actual gravitational waves, confirming the last important piece of Einstein's theory. It's also important because gravitational waves carry information about their inception and about the fundamental properties of gravity that can't be seen through observations of the electromagnetic spectrum.

  8. LISA Pathfinder, a mission led by the European Space Agency (ESA) with contributions from NASA, has successfully tested a key technology needed to build a space-based observatory for detecting gravitational waves.These tiny ripples in the fabric of space, predicted by Albert Einstein a century ago, were first seen last year by the ground-based Laser Interferometer Gravitational-Wave ...
  9. But the study - one of the most precise tests yet of Albert Einstein's theory of gravity at cosmic scales - finds that the current understanding still appears to be correct. The results, authored by a group of scientists that includes some from NASA's Jet Propulsion Laboratory, were presented Wednesday, Aug. 23, at the International ...
  10. When an object moves through space, the distortions turn into waves. Einstein predicted the existence of gravitational waves in 1916, but they weren't observed directly until 2015 by the Laser Interferometer Gravitational Wave Observatory (LIGO). The larger an object's mass, the larger and more energetic the gravitational waves it creates.
  11. This curvature, an idea first proposed by Albert Einstein in 1915, is caused by the gravity of planetary bodies such as the Sun and Earth or by gravitational waves generated by the motions of supermassive objects such as extra-galactic (outside of our galaxy) black holes. As part of LISA, ST7's DRS technology will "ride" the gravitational waves ...
