started the search ekzoplanet terrestrial   At the beginning of last month, we told our readers about the readiness of the conclusion to the space telescope, named in honor of the great astronomer Johannes Kepler. It is an apparatus Kepler Telescope, which just recently was successfully launched into space, and very soon will move into a phase of intensive work.
Recall that the primary goal of a new space telescope is the search for planets outside the solar system. The main focus will be not running at all sites - the number ekzoplanet has long been estimated tens. The focus will be on the so-called terrestrial planets groups, ie, relatively small planets with a solid surface, and located a short distance from the star-mistress. Why does the unit will focus on them ? One of the major challenges of modern astronomy is the search for extraterrestrial life, and it should start with those planets where living organisms to create the most favorable conditions for development.
However, it is to return directly to the Office of Kepler Telescope. The telescope was delivered to the Earth`s orbit launch vehicle Delta II, started on Friday 6 March to launch at Cape Canaveral. The heart of the observatory is a unique fotosensor-resolution 95 million pixels, sensitivity to distinguish very slight changes in the brightness of the object - 84 million share of the initial value. For comparison, the planet similar in size to Jupiter lead to a change in the brightness of stars (an observer) in one per cent - thus observatory will allow detecting a million times weaker changes.
Kepler telescope will move to okolosolnechnoy orbit, being at a respectful distance from the Earth. This allows you to reduce to zero the negative impact of our planet reflected sunlight. In addition, the location of the relative remoteness from the large space allows for the observation of virtually without interruption. Thus, a similar telescope Corot, moving in orbit, may examine any selected part of the sky just over five months.
For the time space telescope will conduct a study about hundreds of thousands of star systems. And the possibility of long-term tracking of objects will allow staff to confirm their data several repeated measurements. The point is that the search for planets will be done by monitoring the brightness of stars, and the periodic change this setting, we can speak about the existence of a specific star satellite. After passage of the planet seems to drive the telescope, scientists will have some stars an array of data that you can check in about a year. It is this period is chosen as the most likely candidate among the planets in the habitable title.
some hope for the successful completion of the mission Kepler telescope gives the fact that more than fifteen per cent of stars like the Sun, found the planet-giants. Thus, the probability of formation of such massive objects is lower than that of the terrestrial planets, which should be part of multiple star systems satellites.
If everything goes as planned, then in the next decade in space travel, two more staff, NASA developed and ESA. Their mission is to continue to ekzoplanet study found. In particular, we will analyze the composition of the atmospheres of these planets, which will give the answer to the question of the possibility of life on its surface.
