Kepler space telescope discovered impossible planets in a cluster of stars

The American scientists analyzed the data collected by a Kepler space telescope in

scattered cluster of stars on a joint of constellations of the Swan and Lira. In one of them the scientists found two small impossible planets. Earlier the existence of these plants was considered as the impossible. Soren Meibom (from the Harvard-Smithsonian center of astrophysics in Cambridge) and his colleagues analyzed the data collected by a Kepler space telescope at supervision over cluster of stars in constellations of the Swan and Lira. In total scientists tracked fluctuations in brightness of 377 stars. In the scattered congestion NGC 6811 in Swan constellation which is removed from on 3 thousand light years, they found two impossible planets which brightness periodically went down. Scientists tracked its changes and came to a conclusion that blinking of these stars arose because on their disk passed rather small giant planets of Kepler-66b and Kepler-67b, whose radius were more than terrestrial everything by 2,8-2,9 times. By their calculations, these planets belong to the class of “mini-Neptune”. These kinds of planets are gas giants with rather large stony kernel which is covered with the ocean from liquid hydrocarbons or water. Because of it their weight is rather low, but by 20 times they heavier than Earth. The fact of existence of Kepler-66b and Kepler-67b in practice shows that impossible planets can be formed in dense cluster of stars. It isn’t clear yet as such “mini-Neptune” endured series of explosions supernew or closes approaching with other stars about billion years of life of congestion. Meibom and his colleagues plan to find answers to these questions during the subsequent supervision with Kepler space telescope.
