A photo from open sources To search for distant worlds on “Very Large telescope “(VLT), owned by the European Southern Observatory, was installed a new device with high power. Device SPHERE or high-contrast spectropolarimetric search engine uses several search methods and technologies in work exoplanets. This allows you to do more detailed research. dust rings around stars, of which, according to scientists, further planets form. Already in the early days of SPHERE managed to get some pretty interesting shots. On photos, provided by the device, an object resembling an Eye is depicted Sauron from the saga of Tolkien’s “Lord of the Rings.” As explained astronomers, actually the photo was captured star HR 4796 of Centaurus constellations. The dust ring surrounding the star creates such an unusual effect in the pictures. According to experts, acquaintances with the work of SPHERE, only such a powerful tool can do it Get photos of similar quality. Moreover, the device designed specifically for such purposes and now perfectly with them coping. The first SPHERE tests were carried out at the end 2013, after which the device was sent to the Paranal Observatory. The main assembly was completed in May of this year, after which SPHERE was installed on vlt. The combination of several advanced technology allows for record-breaking contrast during observations of exoplanets. Therefore, instrument technology much different than the very first device created for observations of distant worlds. According to the chief researcher by Jean-Luc Bozey, SPHERE is a very sophisticated tool. Moreover, the performance of the device in the construction of which many scientists took part, exceeded even the most daring expectations. According to the developers, the main goal of creating devices, were the search and characterization of giant exoplanets, orbiting the stars closest to our system. Feature The method used by the search engine is to directly observe space bodies without using indirect signs presence. The complexity of this task is that the desired exoplanets are usually located close to their parent stars, so it’s almost impossible to make out in the sky. For this reason, the researchers most actively worked on high-contrast SPHERE shots. One of three The technique used by the tool is extreme adaptive optics. It can significantly reduce the interference caused by Earth’s atmosphere through which the telescope observes the stellar the sky. Another method used is coronography, blocks light. coming from a star, which also increases contrast. The third method is differential visualization is used to indicate the difference between the light of stars and exoplanets, in terms of their colors and polarization. This technique helps to find planets that cannot be detected with other instruments. Very first SPHERE tests were in test mode. Scientists in this way checked the operation of the device in various modes. So what is the Eye of Sauron, which is actually the ring around the star HR 4796, depicted in high contrast, has become evidence performance tool SPHERE. Researchers are planning for the future. make many unique discoveries with high contrast search engine.
