A photo from open sources
Employees of the National Accelerator Laboratory. Enrico Fermi made a series of photographs of Comet Lovejoy. Flying heaven the body in the southern sky was photographed using the most powerful on planet camera – “DECam”. Current research will allow new data on the dark energy of the universe.
At the time of shooting, the comet was at a distance of more than eighty-two million kilometers from Earth. One of the authors work, by the way, became a native of the Soviet Union Nikolai Kuropatkin.
“DECam” is a 570 megapixel camera, Designed specifically to study dark energy in space. The device is capable of capturing objects located on up to eight billion light-years from us. Camera built into the four-meter Blanco telescope located in Chilean Andes.
“DECam” has seventy-two chips, each of which captures millions of pixels and transfers them to the research computer. FROM the goal of increasing camera sensitivity by chips is determined rectified light wavelength shifting as you travel towards the earth towards the red spectrum. “DECam” is located in a vacuum at a temperature of minus one hundred degrees Celsius.
Lovejoy’s comet was photographed so close to Earth, as far as the orbit of the celestial body allowed. The comet consists of snow-ice core with a diameter of about five kilometers and the surrounding its clouds are a gala with a diameter of over six hundred and forty kilometers. The image of the comet was composed of sixty two rectangular pictures, each of which was provided separately field of the camera.
The green color that you can see in the photo represents a real color of the comet. This is how she looks right now. This is because gas enters the solar ultraviolet radiation and acquires a bright green color.
