Moonlight sky over the Chinese city of Chengdu could soon be
officials The city recently announced plans to build an artificial moon to be hung over the capital of Sichuan Province by 2020, the Chinese news website People's Daily Online (PDO) reported
Orb is said to be the light of the earth Moon supplement, and will be eight times brighter than the natural satellite, Wu Chunfeng, chairman of the Chengdu Aerospace Science and Technology Microelectronics System Research Institute Co. Ltd. (CASC) ̵
In fact, the light from the artificial moon is expected to save the city's money by eliminating the need for street lighting, Chunfeng added. The new moon, according to the PDO, will be able to illuminate an area of up to 50 miles (80 kilometers) in diameter.
Although the man-made moon will only brighten Chengdu, the glowing ball will be visible throughout China, even the overseas reported "Asia Times." The real moon, of course, can usually be seen from all over the world. However, little is known about the height, size and true brightness of the proposed artificial moon – all factors that could affect its visibility to distant observers.
It is also unknown whether the project has received official city support Chengdu or the federal government, reported The Guardian
This is not the first time that a country has tried to outshine the moon. A similar project was presented by Russia in the 1990s with the introduction of a solar reflector system – a "space mirror" – designed to produce light equivalent to three to five full moons covering an area of about five kilometers in diameter, the New York Times reported in 1993
Another Russian attempt to launch a space mirror in 1999 evaporated, according to The Guardian,
"A Dawning Light"
Concerns about the Chinese artificial moon disrupt astronomical observations or disrupt active animals at night, Kang said Weimin, the director of the Institute of Optics at the Harbin Institute of Technology in China, said the light would only be an "evening dusk". like glowing, "PDO reported.
However, research has shown that many animals are very sensitive to light and moon phases, for example, nocturnal uhus communicate by displaying white throat feathers, and scientists have found that activity increases during the full moon when the moonlight is brightest.
And in the Australian Great Barrier Reef, hundreds of coral species simultaneously release their eggs and sperm in an annual mass spawning event associated with the moonlight level.
The size and lighting technology of Chengdu's artificial moon is not yet available, so it remains unclear whether the brightness of the proposed artificial satellite would actually be intense enough to disrupt the routines of local wildlife.While the company called it "satellite", suggesting that it is in a geostationary orbit – in the sphere the earth above the equator orbits – is introduced, no details, the "artificial moon were published, as the company plans.
