This may look like heaven on newly discovered planet, lighted up by Proxim, Alpha and Beta Centauri (ESO / M. Kornmesser) 1 -> In October, 2012. Astronomers from the European Southern Observatory reported that discovered the planet Alpha Centauri B the size of Earth, which orbits the star in a very tight orbit. Full lap - the local year - lasts only three days and five hours. Because of the proximity of the star the planet is definitely not like the Earth - on the surface there is a murderous temperature, astronomers estimated at more than 1,200 degrees Celsius. Life, as we know, there is rather impossible. But astronomers now then they suspected that this is not the only planet in the Alpha Centauri system. - There may be a more distant planet located in the ecosphere [area of life] - commented for "Election" Alexander Wolszczan, the discoverer of the first planets outside the solar system. Ecosphere is called the area of the star where the temperature favors the remaining liquid water. This is the basic condition for the existence of life in the form as we know it. Proxima, which is the closest In the latest edition of "Nature" group of researchers from the European Southern Observatory reports that around Proxima circulates twin Earth - rocky glob located in the zone of stellar life. the closest to the Sun star is smaller and cooler than the Sun, is called. red dwarf. Revolves around two other stars of this system (Alpha Centauri A and B) in a fairly large distance. Star A and B of this system divides the Earth's distance from the light 4.36 years, or 41 trillion km. Proxima is 1.5 trillion km closer to us. The planet - so far only has a common name Proxima b (the letter "a" is reserved for the stars) - has a mass of about 30 percent. greater than Earth and is located at a distance of 7.5 million km from its star. It orbits it in little more than 11 days. She receives from her about two-thirds of the radiation that Earth receives from the sun, and scientists predict that its surface temperature is approx. -30 Degrees Celsius. Quite cold, but these calculations do not take into account the greenhouse effect, which depends on the thickness and type of atmosphere . If no cushion of greenhouse gases, the Earth also would not be much warmer - barely -20 deg. C. Is Proxima b has an atmosphere? We should learn this soon, when it begins to operate the telescope James Webb. This successor Kepler telescope, which will allow the observation of extraterrestrial atmospheres of planets, should be launched from the French Guiana in 2018. But there is a big problem. Type star Proxima Centauri are very active. Emit hundreds of times more X-rays than the sun and more often than send it into space powerful flares. Both phenomena can strip the planet of its atmosphere, and if it begins there to create life - simply annihilate them. Dramatically reduces the chances that any life forms were created there. On the other hand, the star of this type live many times longer than the type of our sun. Any life will be (or was?) A lot of time to develop there. How discovered Proxima b? at the 3.6-meter telescope at La Silla in Chile belonging to the European Southern Observatory's recently installed highly sensitive HARPS spectrograph. It can measure very small changes in speed of the star. As a result, astronomers are able to detect oscillations in the movement of the star caused by the gravitational attraction of a very small, and so rocky planets. This technique, however, requires constant observation and sophisticated statistical analysis to the measurement data to pick out the signal of the planet and to separate it the different noise. The results must undergo a thorough verification and astronomers usually refrain from announcing the discovery until they are confident the work will be accepted for publication in a refereed writing. It happened after ten years of accurate observations and calculations. We have a chance there to fly? the authors of science fiction often placed the action in the system Alpha Centauri, as if on the local planets known for a long time. The history of the Earth expedition to Alpha Centauri system and finding intelligent civilizations described, for example, Stanislaw Lem in "Magellanic Cloud" in 1955. 40 trillion km is a huge distance. If the Earth to the sun reduced to 1 km, is Alpha Centauri to be situated 270 thousand. km away. A farthest earthly object, which launched in the 70s, Voyager 1 is only 120 km. At this rate the trip to Alpha Centauri would take Voyagerowi some 70-80 thousand. years. But in April of this year, Russian billionaire Yuri Milner, together with a group of eminent scientists announced an ambitious plan to send a probe that could more quickly reach the Alpha Centauri system. Milner has promised to spend on this $ 100 million. The "Breakthrough Starshot" involves sending a probe the size of postage stamp, equipped with a camera and a set of sensors. It has them drive the solar sail area a few meters and weighing just a few grams. For the correct speed (20 per cent. The speed of light, which is 60 thousand. Km s!) Accelerates probe giant lasers with a capacity of 100 gigawatts installed on the earth. Such miniature probe-driven light would reach Alpha Centauri in 20 years, or even for our generation. They could explore the local solar system and send to Earth images and data, which reach us at light speed a little over four years. Perhaps this project will catch now the wind in the sails. But maybe ships? Commission Budget , which allocates resources to NASA, encourages the agency to research drive, which can achieve speeds of up to 100 million km per hour. This has to go to the 100th anniversary of the American landing on the moon, the year 2069th The draft budget calls space agency to draw up a "road map" of such a project within a year. We do not have any ready-made technology that could disperse anything more solid such speed. Congressmen - after specialists earmarking space agency - are aware of this fact and the report suggests several paths that NASA could follow. Interestingly, there are new ideas. Among them such as nuclear drive, which is characterized in that the vessel is fired nuclear charge. This project, called Orion, was developed in 1955. By the co-authors of the hydrogen bomb: Cornelius Everett and Stanislaw Ulam, a Polish mathematician born in Lviv. The program was not abandoned for technical reasons, but because of the treaty banning nuclear tests signed in 1963. Another is the jet engine developed in 1960. By the American physicist Robert W. Bussard. Ramjet is extremely simple in design, have no moving parts, but outside the jet-propelled missiles long-range technical reasons are few applications on Earth. In space, could perform very well. The fuel would be collected by the electromagnetic field of hydrogen, which in space is missing. Maybe we can fly to Proxima b even in this century?

Stop all these stupid visuals!
Webb telescope is to allow observation of atmosphere "alien planet".
Can and are there any terrestrial planets, but the hush .. it's about the next article
This artistic vision of the planet's something strangely reminds me of the crematoria "Chronicles of Riddick"
To discover in "No Man's Sky".

I would recommend trilogy Boruni and Trepka from the mid-50s. One part of this "Proxima". For fans of fantasy is an interesting position.
