CERRO PACHON THE EYES OVER ASTEROIDS IN CHILEAN ANDES
From The Guardian of London says in a article that many millionaires including Bill Gates help to building Cerro Pachon en chilean andean the world biggest digital camera to take images on the sky.The cost 400 US millions.Principal objetive provide early warning of asteroid crush.Rounded by the highest mounts in the southern hemisphere Andean chain rounded Pachon are on average 6.000 meter conteining many glaciers.The largest mirror never contructed in the a laboratory at Arizona University.Yhe main funtion of the Large Synoptic Survey Telescope is survey all sky several times in the week something never made before.The came from the most greatest digital camera in the world with 3.200 megapixeles. Gates said they will pur terabyte of dates rurning astronomy in a software.It will be the first Internet Telescope and in the proyec is shared by 23 Universities,laboratories an private organizations
s of dates, and the Telescope take a picture of size of the moon every 15 seconds.
turn astronomy into a software issue by writing code and database queries to mine the night sky and recover its secrets.
"LSST is truly an internet telescope which will put terabytes of data each night into the hands of anyone that wants to explore it. [It is] a shared resource for all humanity . the ultimate network peripheral device to explore the universe," he said.
The donations will keep on track the construction of three large mirrors and three refractive lenses which are the most important and expensive part of the machine.
The first stages of production for the two largest mirrors are under way at the Mirror Laboratory at the University of Arizona. The teloscope basis is located over 2700 meters above in chilean Andes an his camera is expected take over 200.000 pictures and the end date of contruction is 2011.The short time of 15 seconds is enough to register every fain objet falling in the sky as the mini meteorites
Launched in 2000, the project is a partnership based in Tucson, Arizona, and split among 23 universities, laboratories and private entities. Once the mirrors are ready they will be hauled up the 2,690-metre peak and installed in a dome due for construction in 2011. "First light", as astronomers call their scoping, should begin four years later.
The camera is expected to take more than 200,000 pictures. Processing that information is expected to be the most technically difficult part of the project.
The camera's 15 second exposure should be long enough to record images of even very faint objects such as asteroids and so-called near-Earth objects. By monitoring them night after night, it should be possible to infer their orbit around the sun and hence how likely they are to slam into Earth.
That is how the project's director sold the LSST to congressmen in November. "The ability to detect virtually every potentially hazardous near-Earth object and determine its orbit with precision transforms that statistical threat into a deterministic prediction," said Anthony Tyson, at the University of California, Davis.
But it will also be useful for basic science. Its time-lapse images can be used to create 3D maps of the mass distribution in the universe. That should not only help to trace billions of galaxies, but also tell cosmologists more about the mysterious and recently discovered "dark energy" that is driving the expansion of the universe.
Every night the telescope will pull in 30 terabytes of image data (about 190 times more than a top of the range iPod) which will be made available free on the internet. "People can find out what's going on everywhere in the sky, and no one has ever done that before - not even come close," said Donald Sweeney, the project manager. "There are lots of things that happen every night in the sky, and no one has been able to track them and detect them."
Cerro Pachon, located in northern Chile near the city of Vicuña, is a foothill of the Andes but high enough to escape haze and light pollution. It was chosen over a site in Mexico because it hosts two other large telescopes known as Gemini South and SOAR, delivering a ready-made Other eyes on sky are: The European Southern Observatory's Very Large Telescope in Chile's Atacama desert has produced the first direct images of planets outside our solar system.
· At $1bn the Atacama Large Millimetre Array in Chile will be the world's most expensive observatory. By 2012 it is expected to discover a new galaxy every three minutes.
· The southern hemisphere's biggest optical eye is the Southern African Large Telescope in the Karoo desert.
· The proposed Square Kilometre Array (SKA) will be 100 times more powerful than any other instrument. Construction is due in 2011, with South Africa and Australia competing to be hosts.
