Now we prove the existence of 1783 planets in 1105 planetary systems. And the number of candidates is approaching three thousand. All in all, scientists assume that in our galaxy the milky Way is at least 100 billion exoplanets!
People have long realized that other stars, like the Sun, can have their own planet. And even gave them the name exoplanets or extrasolar planets, i.e. planets outside our Solar system. But to verify the existence of such planets a science was only in the late 1980s. Now it is proved the existence of 1783 planets in 1105 planetary systems. And the number of candidates is approaching three thousand. All in all, scientists assume that in our galaxy the milky Way is at least 100 billion exoplanets. 5-20 billion of them earth-like. Some of the most remarkable exoplanets.
Minitems, that is, exoplanets, which are less in size small even our Earth, Kepler-42 d (also known as KOI-961 d) revolves around the star Kepler-42 in the constellation Cygnus. The radius of the planet is just 0,57 ± 0,18 from the earth’s mass and less than 90 % of the mass of our planet. One year, one revolution around its star, Kepler-42 d lasts for less than 2 earth days. Continue reading
Today, there are many ordinary people who want to visit in airless outer space in order to feel a sense of weightlessness, look at the Sun without atmospheric curtain, and to see our home in the Solar system through the glass window. This is probably due to space companies that provide services to tourism in space. Although the implementation of this idea required a lot of money and not everyone can afford the luxury, worth tens of million $. Most space tourists aim independent research space space, or just fly on the trajectory of Our planet for the sake of entertainment.
25 million $ is a ticket into space on the Russian spacecraft Soyuz. Although the desire to plunge into the world unlike the earth makes people to lay out a round sum. So I-mi space tourists were Japanese toyohiro Akiyama and British citizen Helen Sharman. In 1989-1990 they made a spatial tour on the MIR space station. Sponsors of such projects for the delivery of tourists to the space station were TV TBS and Juno, and as vehicles were made by Union TM11/10 and the Union TM12/10.
Born in Italy and living in the United States Dennis Tito became the first tourist who’s own funds did pay for the flight into space. Continue reading
Second disclaimer: Denis Tito was the first cosmotourist, but not the first astronaut sent into orbit on a commercial basis. Even in 1990, Japanese journalist toyohiro Akiyama visited the orbital station “Mir” as a cosmonaut-researcher. For his training and flight paid Tokyo broadcasting Tokyo Broadcasting System (TBS) for promotional purposes.
But Dennis Tito became the first tourist in the classic sense of the word. He flew to the ISS in order to relax, spend time with pleasure, to film the Earth from the window I. to open a new era in the history of space exploration.
In the office of the Director General of the company “Orbital technologies” Sergey Kostenko – many diplomas for merits in development of space tourism and Photos with celebrities. “We’ve been working in the field of space tourism company Space Adventures, says Mr Aksyonov. – Initially it was just a workout space, and then, in 2001, there was Dennis Tito marked the beginning of a real flight.
