NASA announced the discovery of 10 more earth-like planets Source:

Astronomers at the American space Agency NASA on Monday announced the opening 219 new objects outside the Solar system, most of which may represent the planet. Furthermore, astronomers believe that 10 worlds of this list are planets of terrestrial group and may be inhabited.

Scientists have new evidence thanks to mission space telescope "Kepler" and going from March 2009 to may 2013. During this time Kepler had to learn 145 000 sun-like stars, in the constellation Cygnus. Most of these stars are located hundreds and even thousands of light years from us, so we are unlikely there ever get. At least certainly not in the near future. Nevertheless, the collected information can tell astronomers about how often in the Universe can meet the terrestrial planets and what are the chances that we will one day be able to detect on one of them some intelligent extraterrestrial life.

"with this telescope we will be able to calculate in this phase space the number of planets similar to Earth. For us this question is the key. And now we have all the data to find the answer. We want to find out how often unable to meet the exoplanet and many of them may be suitable in order to someone could call their house" — commented on in the course held on Monday at the Research center Ames press conference, Susan Thompson, an employee of the SETI Institute, working with the space telescope "Kepler".

Given the previous discovery of "Kepler", with these ten new planets of terrestrial group, the total number of discovered planets in the same category now stands at 49, points out Thompson. If any of them has a stable atmosphere, the chances of detection of life will increase dramatically.

In fact, scientists are not yet ready to talk in more detail about these 10 new confirmed planets. All that is currently known – the planet belong to the earth-like type, have similar size and are located in the habitable zones of their stars – the region of space where the planets is theoretically possible to maintain water in a liquid state.

This "exhaustive" information, as you know, does not guarantee that the planet can actually be inhabited. Indeed, in addition to stable atmosphere, the most suitable conditions for habitability require a stable tectonics, and the absence of tidal capture.

And yet the scientists of the mission "Kepler" I believe that we can expect the discovery of many earth-like planets, many of which we are simply unable to find because of the peculiarities of the operation of the telescope the researchers used the transit search method, that is, they learn about the planet when it passes in front of its star, reducing its brightness.

Due to the fact that most of the detected exoplanets are in the same plane and this plane rarely meets earth, Kepler is able to see only a small fraction distant from our star systems. A feature of the inclination of the majority of exoplanets in relation to their stars only complicates their search. But despite these difficulties, "Kepler" has found 4034 planetary candidates, of which the official status of exoplanets has already received 2335 objects. And it's only 0.25 percent of total apparent us of the night sky.

"To do an effective search you'll need 400 telescope "Kepler" — shared at the press conference, Mario Perez, a scholar of the program "Kepler" from NASA.

According to speaking at the meeting, Benjamin Fulton, astronomer, California Institute of technology, and a fellow of the University of Hawaii at Manoa, the majority of discovered exoplanets belong relatively new to us class a "mini-Neptune". These worlds are something of a cross between gas giants and planets the size of Earth and, according to many astronomers, are one of the most common types of planets in the Universe. To the other less common type are the so-called super-Earth — the rocky planets, in some cases up to 10 times more massive than our Earth.

Despite the fact that, among all discovered to date, only 49 of exoplanets have the same size of earth and are in the habitable zones of their stars, from the point of view of statistics this can only mean one thing: only one of the milky Way may exist billions of these worlds.

the search Area telescope «Kepler»

"This is only the smallest fraction of what awaits us. Personally, I'm just excited," — shared at a press conference, the Caltech astronomer Corti Dressing.

"Kepler" has finished collecting the first data packet within the framework of its initial mission in may 2013. The analysis of the information received, scientists have taken years. Analysis, interpretation and proof demanded of the enormous number of man-hours. As noted at the meeting Thompson, the new data will be the last step of the scientific work conducted within the very first planned mission of the telescope. Recall that "Kepler" has twice experienced problems with the equipment (and is having some problems now), which ultimately restricted his ability to spot analysis. Now he can't stabilise and investigate a single target, this means that the initial mission to study sun-like stars, it is now possible to execute not.

However, the scientists came to the decision and launched a mission called K2, which was launched in may 2014. In the course of its shortcomings in accurate focusing "Kepler" special value does not play, so the telescope has been monitoring a variety of cosmic objects such as supernovae, young stars, comets and even asteroids.

Although the K2 mission is still just gaining momentum, other telescopes have already managed to achieve some success in similar projects. For example, in February of this year scientists announced the detection of seven earth-like planets within a single system one of the stars of the class of red dwarfs.

The Stars of this class are, according to astronomers, one of the most common in the Universe. They have one very unpleasant feature. Their surface often produces emissions of matter. The paradox is that the most compact earth-like worlds located in the habitable zones of their stars are next to this type of light. Who knows, maybe it really is the best target to search for life.
