From our nearest star system found a planet – technology – innawoods

From our nearest star system found a planet — technology — original title: from our nearest star system found a planet in this week’s "natural" magazine published a cover position in astronomy of important discoveries, a small rocky planets orbiting Proxima Centauri, which is Proxima Centauri is the nearest stars. The new planet is named B (Proxima b) Proxima Centauri, a mass of about 1.3 times that of the earth, the surface temperature of the liquid water existence theory allows. Next star is a red dwarf, only 4 light-years away from the solar system a little more, so it is human study of low mass stars is one of the most in-depth. Since mid August, foreign media news scientists have discovered the terrestrial planets in the next star, but has not been confirmed. London Queen Marie Anglada Escude Gilliam? – Doppler and colleagues, the analysis of measurement data of two of the European Southern Observatory telescope collected from 2000 to 2014, and collected between January 19th and March 31st this year, a series of observational data. These data can be measured by the rail potential planetary gravity ruler perturbation (perturbation). Finally, the researchers obtained the actual confirmation — 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 km, equivalent to about 5% of the earth from the sun. Such orbital cycles make the planet Proxima B in the habitable zone of its star, which means that its surface temperature theoretically keeps water in liquid form. From the maintenance of the atmosphere and maintain the liquid water in two aspects, such as Proxima B this kind of habitable planet is still controversial. Therefore, further research is needed to confirm the characteristics of the atmosphere in the next few decades, and to evaluate its ability to support life. In addition, the planet Proxima B orbit is close to its star, which means that it is subject to the X ray flux is much higher than the earth, and whether it has a protective magnetic field as the earth does not know at this stage. In the next few hundred years, the use of robots to explore the planet Proxima B or will become possible. In the news and articles about the view of this thesis, the American astronomer Artie? Heitezi concluded, Proxima Centauri life than the sun long hundreds or even thousands of times, in a very long time after the death of the sun, any life may exist on the planet will still keep evolving. Chief editor punctuate the Alpha Centauri system (Proxima Centauri is one of the three stars) is very close to the earth, many science fiction "that" there is cosmic and biological civilization developed. A few years ago, scientists calculated that in October 2014 and February 2016 respectively, the two "body" (the background, Proxima Centauri star and earth connection) event, took the opportunity to peep if there are planets orbiting Proxima centauri. The conclusion of this paper is based on second observations. However, only 4.2 light-years from the sun is near Proxima Centauri "close", people take the fastest rockets still need 17 thousand years back and forth. Hopeless? To read the Hugo prize for fiction "body"! (Zhang Mengran) (commissioning editor: Zhao Ying)相关的主题文章:
