Scientists Rene Heller and Ralph Pudrits Germany offer significantly narrow down the search area potentially habitable planets. . More information can be found in the journal Astrobiology

Currently, there are several methods to search for extrasolar planets – planets that orbit other stars. One is the so-called main transit method. It lies in the fact that astronomers have observed the weakening of the brightness of stars when between the observer from the Earth and the star passes the planet. Such an event is called “transit”. The method allows to determine both the mass of the planet, and many of its properties.

The authors of the new work suggest to concentrate efforts to find a signal from extraterrestrial civilizations in the transit area. It is a narrow region of the sky where the transit of the Earth on a background of the solar disk can be detected. Scientists estimate that in the transit zone may be about 100 thousand of potential targets, the signal from which we can find modern methods

«It is difficult to say whether aliens use the same methods of observation that we.. – says René Heller of the Institute of astrophysics in Göttingen – but they will have to deal with the same physical laws that we, and the transit of Earth across the disk of the sun – is an obvious way we discover »

Scientists believe. that if Yuri Milner project to search for extraterrestrial life Breakthrough Listen focus on searching in the transit area, it will have a much greater chance of success
