Educational observatory This is a partial list of astronomical observatories ordered by name, along with initial dates of operation (where an accurate date is available) and location. The list also includes a final year of operation for many observatories that are no longer in operation.
The European Gravitational Observatory (EGO) is a consortium established to manage the Virgo interferometer and its related infrastructure, as well as to promote cooperation in the field of gravitational wave research in Europe.
The Virgo interferometer is a large-scale scientific instrument near Pisa, Italy, for detecting gravitational waves.The detector is a Michelson interferometer, which can detect the minuscule length variations in its two 3-km (1.9 mi) arms induced by the passage of gravitational waves.
Einstein Telescope (ET) or Einstein Observatory, is a proposed third-generation ground-based gravitational wave detector, currently under study by some institutions in the European Union. It will be able to test Einstein 's general theory of relativity in strong field conditions and realize precision gravitational wave astronomy.
Gravitational waves were first predicted in 1916 by Einstein, who was trying to understand how gravity moves in the cosmos. Learn about gravitational waves and how a Tri-Cities observatory spots ...
M1 – Solar Orbiter, launched February 2020, operational – Solar observatory mission, designed to perform in-situ studies of the Sun at a perihelion of 0.28 astronomical units. M2 – Euclid, launched July 2023, operational – Visible and near-infrared space observatory mission focused on dark matter and dark energy.
Gravitational waves (GW) are small disturbances in space-time, caused by the motion of masses, if the third time derivative of the mass quadrupole moment is non-zero. These waves are very weak, such that only the strongest waves, caused by the rapid motion of dense stars or black-holes, have a chance of being detected.
The International Pulsar Timing Array (IPTA) is a multi-institutional, multi-telescope collaboration [1] comprising the European Pulsar Timing Array (EPTA), the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), the Parkes Pulsar Timing Array (PPTA) in Australia, and the Indian Pulsar Timing Array Project (InPTA [2] [3]).
