According to the United States "explore" magazine website reported that American scientists will be officially opened this month, the world's largest digital camera for observation and search for possible asteroid crashed into earth. This biggest digital camera is located in Hawaii, and its image quality up to 14 million pixels.
This digital camera has been installed on the PS1 telescope, it is a called "english panoramic telescope system and rapid response" (Pan-STARRS) project. The system is built on the island of Maui, Hawaii United States, in part by one of a 4 composed of two telescopes, PS1 is one of the telescope. "Pan-STARRS" will regularly scan the sky, searching for possible impact on the Earth constitutes a dangerous asteroid.



Camera has a 40 cm across the surface of the optical probe, on its surface there is an independent integrated circuit chip 60, are able to receive up to 14 million pixels photo. But the average consumer to use the ordinary digital camera imaging of integrated circuits, only a few millimeters wide. Institute for Astronomy at the University of Hawaii John - Tony led the construction of the camera team, he said: "This is a great camera size. it so that we can at the same time 1.4 billion at the location of measurement of the brightness of the sky." Astronomical Institute The "Pan-STARRS" program, the Institute director Rolf Peter said: "This camera is a highly complex equipment, it has been running the Institute of Astronomy of scientists and engineers outstanding achievements. "

From the beginning in 2010, when the "Pan-STARRS" plan finish all four telescopes, it will take from Hawaii three times per month can be seen throughout the pictures of the sky. This should be able to detect it than the current 100 times weak english celestial bodies, including 99% of the near earth orbit 300 meters wide or larger asteroid. NASA will be expected to orbit the Earth at around 90% found in the vicinity of the 1 km wide or larger asteroid. For even smaller mini - planets are relatively poor search capabilities. However, because the number of smaller asteroids more, so they are likely to impact the Earth more.

NASA has asked the U.S. Congress in 2020 to identify 90% smaller asteroids, of which only the smallest asteroid 140 meters in diameter. But NASA said that they currently do not have enough capital and manpower to carry out the search.
