There could be habitable planets around the Tau Ceti, the nearest Sun-like star

New data are referring to this. Two planets looks like very exciting.
We could use to it that the number of the exoplanets are growing month by month and besides these are more and more often appearing smaller, ones that nearly similar to the planet Earth as well. Now they published the result of a newer study which can be exciting to experts/specialists/professioanals.
According to the published announcement on the website of the Hertfordshire University, we are talking about the planets around the Tau Ceti from which at least 4 of them are inside the system. Because of the fact that the star are similar to the Sun, the system are forming an ideal target because we can best (most easily) imagine by starting from our own example that there could be similar planets to planet Earth in other solar systems. The distance are neither huge, this approximately 11 light years, so the possibility is arising/emerging that one day even humans can reach these planets. Now this is looks even more attractive because two planets are inside the habitable zone and they are only 1,7 times bigger than the Earth.
The two planets in question are have solid surfaces, one of them is on the inner edge of the habitable zone and the another one is on the outer edge. They detected them by observing their gravitational effects. however the original signals observed in 2013 are not yet referred to existence of planets. They obtained the data with the help of the European Southern Observatory and the Keck-HIRES and they will publish it in the Astronomical Journal, however one member of the team (Dr Mikko Tuomi) are already made the fact obvious that the more accurate result is made possible by the painstakingly improved sensitivity of the techniques. There could be at least four planets around the star, however the situation is complicated by the fact that there can be also find significant amount of debris so we can't exclude the possibility that the planets in question are affected by serious impact.
The observation of the two outer planets are keep going. we could get more precise data in the future.
