In the Astronomy & Astrophysics magazine was published an article of group of astronomers from Chile, Australia, Britain, the United States led by Mikko Tuomi from United Kingdom, that they found a potentially habitable planet at the famous star Tau Ceti, which in 1960 the American scientist Frank Drake made the first goal of the "Project Ozma" to search for extraterrestrial civilizations by listening for radio signals from the star. According to Mikko Tuomi, Tau Ceti star (HD 10700) is visible in the sky as a star of the third magnitude, it is located 11.9 light years off Earth and is very similar to our Sun, since it has the same spectral type (G) and the same age, her weight is 78.3% of the mass of the Sun. According to Hugh Jones , co-author of the study, in the observations of the star Tau Ceti used a new method for high-precision radial velocity measurements by comparing the speed of the star to the observer and from the observer, using the data of the star Tau Ceti at the same time from three spectrographs: HARPS spectrograph at the European Southern Observatory in Chile, spectrograph UCLES on the telescope in Siding Spring, Australia and spectrograph HIRES at the Keck Observatory telescope in Hawaii. As a result, periodic oscillations were observed with radial velocity of the star Tau Ceti, which prove the presence of planets in stable orbits with periods of 13.9, 35.4, 94, 168 and 640 days, THE VIDEO:
