Imagine that you brontosaurus, prehistoric times, and chew the leaves on the crowns of trees. You and your family have ruled the earth 150 million years. Huge and powerful, you feel invincible. But alas it is not. Let us from the era of the dinosaurs 65 million years. There is a much smaller and weaker than the Earth is dominated by the brain, but not with muscle. His brain is much more compared to the size of the body – it is large enough to invent way to scan the cosmos for tracking larger asteroids that have led to the death of the dinosaurs.
Username Man Man was designed and built WISE, wide infrared telescope to search for "dark" objects in space, such as, brown dwarf stars, a huge cloud of dust and asteroids approaching Earth. WISE scans such objects due to its high sensitivity to infrared radiation, which unavailable to most other telescopes. "Our unit is tens of asteroids every day who could not find before," said Ned Wright, principal investigator for WISE and physicist at the University of California, Los Angeles. WISE, designed for this purpose. " Most asteroids, which scans WISE, located in the asteroid belt between Mars and Jupiter, but some of them are different kinds of giants, which approaches the Earth, forcing spine shiver with brontosaurus. WISE has been in orbit for about three months, but we have already found several asteroids, which are classified as 'potentially dangerous', including one that is detected as early as 1996, but in the process observations, have lost sight of.
To asteroid has been named a "potentially dangerous", its orbit must pass at a distance of approximately 8 million km from Earth's orbit. One of the discoveries was the asteroid in the constellation of the Cross, its orbit will be approximately 1100000 km from the orbit of the earth. WISE tracks the trajectory of each potentially dangerous object in Earth orbit. It scans the cosmos, every three hours, and then carrying out a "short track" – forecast where the object will be in the next few weeks. Team WISE, sends the information to NASA, funded by the Minor Planet Center in Boston. They placed this information on a public site where Scientists and amateur astronomers will be able to continue to monitor the asteroid. The asteroid, which scientists believe killed the dinosaurs was about 10 km in diameter. The chances of such a strike today practically does not exist, but it is not means that we are out of danger. Smaller asteroids are many, and they can significantly harm the Earth. More recently, in 1908, for example, an asteroid the size of several tens of meters in diameter exploded over the river Tunguska, Russia, and killed eight hundred square kilometers of forest. "The damage caused by small asteroids can be very serious," Wright says. "We have to watch the sky to find these objects and to measure accurately their orbit. If we can find a really dangerous asteroids in time, we will have time to take adequate measures to eliminate, or rejection of the orbits of these objects. " Many telescopes are already working with such programs. Most well-known programs; LINEAR, Catalina Sky Survey and others. Working together for many years, they found more than a thousand potentially hazardous asteroids. WISE contribution to the common cause would be impressive. In the period before the end of October, according to Wright observatory will find a hundred thousand asteroids, mostly in the main belt between Mars and Jupiter, and hundreds of near-Earth objects. Such achievements, even brontosaurs will be appreciated.
