A planet is in the galaxy of M 31 (fog of Andromeda), in 2,5 million light years from Earth, talked in the article of group of scientists from Italy, Switzerland, Spain and Russia. It is presently known more than 300 ekzoplanet (planets at other stars, being outside the Planetary system). However much all planets found until now were in our star
in the distance about 20 thousand light years.Straight ekzoplanety looking after is impossible, however them it can find
own motion of luminaries on their spectrums.Within the framework of work researchers studied possibility of one application of methods of search of ekzoplanet – method of gravity mikrolenzirovaniya for the search of more remote planets. He allows to find out planets
on the vibrations of distortions of light of distant stars, caused by the gravitation of the system of zvezda-planeta. a method is based on circumstance that, in obedience to the theory of relativity, massive objects are able to decline motion of light ray. Thus, for example, large
a star, passing between an observer on Earth and distant source of light, is able to influence on visible brilliance of source. Moreover, if at a star a planet is present, then the curve of dependence of brilliance from time has some features.These features, indicative
in the presence of planet, researchers succeeded to discover to the curve of brilliance of event PA-99-N2, which was incorporated in 2004. Initially the phenomenon was interpreted as a result "works" double star system. New calculations show that in given
case a lens was created by a star round which planeta-gigant is revolved with mass about 6 yupiterianskikh, reports Lenta.ru.
