What is HR 6819 that has been discovered by the European Southern Observatory?
What is HR 6819 that has been discovered by the European Southern Observatory?
Answer: [B] Black hole. Notes: A team of astronomers using the Chile-based La Silla Observatory of the European Southern Observatory (ESO) has recently discovered the nearest black hole from Earth. This triple-structure black hole named as HR 6819, is located just 1000 light-years from Earth.
Where in Chile is the observatory?
Atacama Desert
The La Silla Observatory is located on the outskirts of the Chilean Atacama Desert, 600 km north of Santiago de Chile and at an altitude of 2400 metres.
Who Funds European Southern Observatory?
ESO is primarily funded by contributions from its Member States. The total annual Member State contributions to ESO are approximately 150 million euros, or about 0.20 euros per person in Europe per year.
Can we see black holes with the naked eye?
No, it is not possible to see a black hole directly because it does not reflect light. But it is possible to see the violent effects on matter and light close to a black hole and that will be one hell of a spectacle.
Who found HR 6819?
Monika Maintz
History of discoveries In 2003, Monika Maintz concluded the spectrum of HR 6819 contained the signatures of two stars, though there were not enough observations to deduce an orbital period.
What happens at an observatory?
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysical, oceanography and volcanology are examples of disciplines for which observatories have been constructed.
Where is the ESO located?
Although ESO is headquartered in Germany, its telescopes and observatories are in northern Chile, where the organisation operates advanced ground-based astronomical facilities: La Silla, which hosts the New Technology Telescope (NTT) Paranal, where the Very Large Telescope (VLT) is located.
Is Eso part of UK?
In July 2002, the UK became the tenth member of the European Southern Observatory (ESO) (link opens in a new window)|. ESO is an intergovernmental astronomical research organisation, operating a suite of telescopes at the Paranal and La Silla observatories in Chile on behalf of its Member States.
Why are there so many observatories in Chile?
Much of the reason for that lies in the desert skies, which are among the clearest on earth. Radio telescopes pick up wavelengths from outer space, but the signals are often distorted by water vapour in the earth’s atmosphere. By building at altitude, in dry air, engineers can get above some of that moisture.
What is the European Southern Observatory?
The European Southern Observatory (ESO), formally the European Organisation for Astronomical Research in the Southern Hemisphere, is a 16-nation intergovernmental research organization for ground-based astronomy. Created in 1962, ESO has provided astronomers with state-of-the-art research facilities and access to the southern sky.
What is the history of the southern hemisphere telescope?
On January 26, 1954, an ESO declaration was signed by astronomers from six European countries expressing the wish that a joint European observatory be established in the southern hemisphere. At the time, all reflector telescopes with an aperture of 2 metres or more were located in the northern hemisphere.
When was the first ESO observatory built?
On November 15, 1963 Chile was chosen as the site for ESO’s observatory. The decision was preceded by the ESO Convention, signed 5 October 1962 by Belgium, Germany, France, the Netherlands and Sweden. Otto Heckmann was nominated as the organisation’s first director general on 1 November 1962.
Which telescopes are not operated by ESO?
La Silla also hosts several national and project telescopes not operated by ESO. Among them are the Swiss Euler Telescope, the Danish National Telescope and the REM, TRAPPIST and TAROT telescopes. The Euler Telescope is a 1.2-metre telescope built and operated by the Geneva Observatory in Switzerland.
