Royal Observatory Greenwich has been the key to astronomy and navigation since its inception.
At least international standard time.
However, few people realize that nothing has been observed in the observatory for more than half a century.
Astronomers were forced to give up their work in the 1950 s because the smog in London was getting worse and they could no longer see the stars through their telescopes.
With the expansion of the nearby railway, the rumble of the train also makes it impossible to accurately read with sensitive instruments, and
The growing capital has brought about increasingly dazzling light pollution.
Now, more than 60 years later, a new telescope has been installed in Greenwich to restore its position as a working observatory again.
Now London's air is not only cleaner, but modern telescope filters can eliminate pollution and hone in stars, planets, nebulae and even galaxies.
Dr Louise Thuy, curator of the Royal Observatory in Greenwich, said: "As Greenwich has been expanding, the Observatory has really started to shut down in 1948, with smoke billowing from Greenwich Power Station and telescopes becoming useless.
"They used to do magnetic and meteorological readings from here too, but Railways and railways
The frame building interferes with the signal, and the vibration of the train makes accuracy impossible.
With the new telescope, we can handle everything using filters and software.
"The Royal Observatory, established by Charles II in Greenwich in 1675, aims to improve sea navigation by astronomical means and map fixed positions of stars.
Until 1957, the site and its instruments were transferred to Herstmonceaux, Sussex, while the Greenwich site was preserved as a museum and outreach center to encourage public interest in astronomy.
But last year, the Royal Museum of Greenwich launched a campaign to restore the observatory's working conditions, raise more than 150,000 pounds to buy telescopes, and transform its second-class Altai zimes Pavilion, A festival-free Victorian masterpiece designed by naval engineer William crisp.
Anne Manu space telescope (AMAT)
Named after one of the first female scientists to work at the observatory, it is actually four different telescopes, one of which will enable astronomers to produce high magnification observations of the moon and planets in the solar system.
AMAT also has a solar telescope to record the changes in the sun, a practice that Greenwich astronomers began in 1870 and what Anne manoud himself did in the 1900 s.
Astronomers Brendan Owens said: "urban astronomy has made great progress and we must thank amateur astronomers for enabling us to do so.
"We now have filters that can completely block the wavelength of light emitted by things like street lights, and just focus on hydrogen, oxygen and sulfur dioxide from stars and planets.
"In addition to the highly enlarged images of the sun and moon, we also have a cool digital camera that can take very wide skies so that we can see nebulae and galaxies.
"Astronomers hope to use the observatory to witness the lunar eclipse in July 27, when the moon will turn deep red near the horizon --
Called Blood Moon-
When it fully enters the shadow of the Earth.
Mr Owens added: "It should be very spectacular because it is very close to the horizon, so it should look big and red.
We can also use red to tell us about the pollution in the air, because the color of the moon changes during the solar eclipse.
"They also want to see how Mercury will cross in front of the sun next year.
Annie Maunder joined the observatory for the first time in 1891 to process data as a "lady computer", one of the few paid opportunities for women in the astronomical field at that time.
When she got married in 1895, she was forced to give up the position, but she continued to do scientific research with her husband and began a solar eclipse adventure around the world.
Their joint work in drawing the sunspots map establishes the link between solar activity and the Earth's climate, which lays the foundation for modern understanding of the sun and its cycles.
The tour of the facility and the Altai Zimu pavilion will be booked throughout the year.
Visitors will also have the opportunity to see through the interactive screen the images made by the telescope, which will be displayed in the exhibition space, due to the opening later this summer in the underground of the Altai Zimu Pavilion, this will also tell the story of Anne mayend.
On Friday, December 5, 1952, London was paralyzed by a thick yellow smoke.
The worst impact lasted nearly five days, killing as many as 10,000 people.
Due to the unusually cold and windy weather in Europe, smog has shut down traffic and trains;
The theater was closed because the audience could not see the stage.
The government says 4,000 people have died, but the coffins of the mourners have been used up, and historians now say there are far more deaths.
The fact that London was the world's largest city at the time, and that almost 8 million of residents used open-air coal increased the situation.
