Shooting star "program targeting" Proxima B "– science and technology — people.com.cn original title:" photo star "program at" Proxima B "reporter Zhang Mengran on the morning of 25, the British" nature "published in the journal papers that astronomers have found a terrestrial planets orbiting Proxima Centauri, running from the sun only 4 light-years away a little more. It was named B (Proxima b) Proxima Centauri, a mass of about 1.3 times that of the earth, located in the habitable zone, the surface temperature of the liquid water existence theory allows. The discovery, through rigorous peer review, is known as the pinnacle of astronomical exploration over the past 30 years. New exploration target Centauri star Alfa by three stars, numbered A, B stars and C stars, the Centauri star Alfa C aka Proxima Centauri, is the nearest stars. Near the star itself is a red dwarf, is our next door neighbor ", thus become one of the most in-depth study of low mass stars. Since the middle of this month, the foreign media frequency there are rumors that scientists have discovered terrestrial planets in Proxima Centauri, but the public has not been confirmed. London Queen Marie University team analyzed Doppler two measurement data collected at the European Southern Observatory telescope from 2000 to 2014, a series of observational information collected between January 2016 and March. These data suggest that small perturbations of gravitation by potential planetary orbit under the ruler, finally confirms there is actually a quality of the earth warm planets are around the Proxima operation period of 11.2 days, from Proxima Centauri is about 7 million 500 thousand kilometers, equivalent to the distance of the 5%. This means that the orbital period of B in its Proxima Centauri star’s habitable zone, the surface temperature can keep the water liquid. To assess whether it supports life, it is necessary to further confirm the characteristics of the planet’s atmosphere from two aspects of maintaining the atmosphere and maintaining liquid water. B X and Proxima ray flux is much higher than that of the earth, whether it can have a protective earth like magnetic field, currently unknown. But no doubt, the star will become the next few decades, the first goal of human search for evidence of life in the universe. Shooting star "program has been locked on the second day of the announcement, the $100 million" breakthrough photo star "program announced their target Proxima B. Shooting star "program in April 2016, by the famous scientist Hocking and Russian billionaire investor Milner jointly launched the internet. The idea of using the traditional maternal rocket launch spacecraft, thousands will be equipped with solar sail "nano spacecraft to earth orbit altitude, high-energy laser will be in a few minutes" nano spacecraft "up to 20% of the speed of light, its drive to the target. The plan was announced after widespread questioning of engineering and technology, but the project sponsor believes that "nano spacecraft" feasible. Now, the "photo star" task, chairman of the Advisory Committee of Harvard University physicist Loeb said, Proxima B found that task provides a clear goal. When equipped with cameras and color filters will be filmed and aircraft)相关的主题文章:
