NASA arranged to watch the transit of Venus until 2117


NASA and other EU institutions are arranged to watch the transit of Venus between 5 and 6 June, with dozens of activities to capture the best images from this moment not ensue again until 2117. The transit occurs when Venus passes directly between Earth and the Sun, which will see the planet as a tiny dot gliding slowly across the sun king, a phenomenon that was seen by astronomers as Galileo Galilei. Scientists from the sixteenth and seventeenth observed transits of Mercury and Venus, the two planets "inside", to measure the distance from Earth to the Sun in an effort to estimate the size of our solar system.
But, but "we already have that number calculated, transits are still useful," he said in a statement Frank Hill National Solar Observatory (NSO). The last transit of Venus in this century "will help you gauge the different instruments and hunting atmospheres of extra solar planets, "to learn how to evaluate other solar systems in our search for life in the universe. The NSO will use their telescopes in Arizona, New Mexico, California, Hawaii, Australia and India to record the moment with hundreds of images published in real time on your website. The NSO telescopes seek to obtain additional measurements of the structure of the atmosphere of Venus looking spectral traces produced by CO2 emissions, abundant in the atmosphere of Venus. With a large gathering at Mauna Kea (Hawaii), considered the best on the planet to see the traffic, NASA will broadcast the event live on your page and connect with experts and centers in 148 countries around the world who will perform monitoring activities. The agency U.S. space provide images from the International Space Station (ISS), the Hubble Space Telescope and Solar Dynamics Observatory (SDO, in English). U.S. astronaut Don Pettit, ISS crew member, will become the first human to witness and photograph the transition from space to share near real time. Transits of Venus are somewhat unusual and have therefore been little opportunity to photograph them from Earth, much less from Earth orbit. "I've been planning this for a long time," Pettit said in a NASA statement. Pettit point your camera over the side windows of the dome of the space station, a module-observatory built by the European Space Station provides an overview wide angle of the Earth and the cosmos through its seven windows. The observatory Free Internet and mobile application "Slooh Space Camera", which lets you explore space without leaving home, show images from the solar telescopes in Australia, Japan, New Zealand, Hawaii, Norway, Arizona and New Mexico. Slooh will also keep track of Venus beginning at 22.00 GMT (16:00 hrs. of Mexico City) on day 5 with the participation of scientists, filmmakers, engineers and science as Bob Berman, a columnist for "Astronomy Magazine" which will explain to viewers the process. "The transit of Venus is extremely rare," said Bob Berman, because, "once a transition occurs, is followed by another in just eight years less two days, but then must spend 105 years and a half to make it happen another pair of transits eight years apart. " The last thing you saw was the June 8, 2004 and the next is calculated will be in December 2117, making that next week will be the seventh documented traffic observed by humans since the seventeenth century, according to the expert. The event, preceded only by those that occurred in 1639, 1761, 1769, 1874, 1882, in addition to 2004, has generated great excitement and experts warn that, for the enjoyment is complete, do not look at the sun without the proper equipment, it can cause retinal damage and injuries the eye.
