The clock tower. The oldest part of the Orloj, the mechanical clock and astronomical dial, dates back to 1410, when it was created by horologist Mikuláš of Kadaň and Charles University professor of mathematics and astronomy Jan Šindel. The first recorded mention of the clock was on 9 October 1410. [2]
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.
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.
The Virgo interferometer is managed by the European Gravitational Observatory (EGO) consortium, which was created in December 2000 by the French National Centre for Scientific Research (CNRS) and the Istituto Nazionale di Fisica Nucleare (INFN). [6]
The tower of the Old Town Hall has an art nouveau astronomical clock, installed in 1907. [18] Prostějov. The astronomical clock in the tower of the New Town Hall was installed in 1910. Kryštofovo Údolí. The Kryštofovo Údolí astronomical clock is a modern astronomical clock (inaugurated in 2008), built-in a former electrical substation.
In June 2020, astronomers reported details of a compact binary merging, in the "mass gap" of cosmic collisions, of a first-ever 2.50–2.67 M ☉ "mystery object", either an extremely heavy neutron star (that was theorized not to exist) or a too-light black hole, with a 22.2–24.3 M ☉ black hole, that was detected as the gravitational wave GW190814.
In Song dynasty China, an astronomical clock tower was designed by Su Song and erected at Kaifeng in 1088, featuring a liquid escapement mechanism. [2] In England, a clock was put up in a clock tower, the medieval precursor to Big Ben, at Westminster, in 1288; [3] [4] and in 1292 a clock was put up in Canterbury Cathedral. [3]
