The WorldWide Telescope was designed to be the embodiment of a rich virtual observatory client envisioned by Turing Award winner Jim Gray and JHU astrophysicist and co-principal investigator for the US National Virtual Observatory, Alex Szalay in their paper titled "The WorldWide Telescope". [15]
The maps show European country borders at regular intervals of 100 years, but not year by year. [4] This leaves out many important turning points in history. Euratlas is considered a digital humanities company, and a scholar research software [ 5 ] used in the field of historic cartography . [ 6 ]
This list of the largest optical reflecting telescopes with objective diameters of 3.0 metres (120 in) or greater is sorted by aperture, which is a measure of the light-gathering power and resolution of a reflecting telescope. The mirrors themselves can be larger than the aperture, and some telescopes may use aperture synthesis through ...
The European VLBI Network (EVN) is a network of radio telescopes located primarily in Europe and Asia, with additional antennas in South Africa and Puerto Rico, which performs very high angular resolution observations of cosmic radio sources using very-long-baseline interferometry (VLBI). The EVN is the most sensitive VLBI array in the world ...
2007 – First light at Gran Telescopio de Canarias (GTC), in Spain, the largest optical telescope in the world with an effective diameter of 10.4 meters. 2021 — James Webb Space Telescope (JWST) , was launched 25 December 2021 on an ESA Ariane 5 rocket from Kourou, French Guiana and will succeed the Hubble Space Telescope as NASA's flagship ...
CSRH is an interferometer under construction in China. The CSRH will consist of 100 telescopes covering 0.4–15 GHz. 40 telescopes of 4.5 m cover 400 MHz – 2 GHz and 60 telescopes of 2 m cover 2–15 GHz. CSRH will be one of the world's largest and most advanced imaging spectroscopy instruments.
Between 2004 and 2013, more Central European countries began joining, expanding the EU to 28 European countries and once more making Europe a major economical and political centre of power. [235] However, the United Kingdom withdrew from the EU on 31 January 2020, as a result of a June 2016 referendum on EU membership . [ 236 ]
