Every so often, possible brothers of planet earth. However, not every day the observation of up to 59 neighboring planets of the solar systemof which a dozen offer a priori the conditions for life or even a future move of human beings.
In this case, the announcement has had active Spanish participation because it has been produced thanks to a spectrograph developed in collaboration with German institutions in the so-called CARMENES project. More than a dozen organizations researched and funded to place this tool of greater precision the Calar Alto telescope.
For four years they have carried out a tracking by 362 nearby cool stars in search of habitable rocky and temperate exoplanets. They have classified the planets according to the star type protagonist in their space and have recorded the time it takes to orbit around his star. With these data, they have analyzed whether the observed planets are potentially habitable.
The numbers of the research published in the scientific journal in Astronomy & Astrophysics They are exciting for the scientific world. “Since it came into operation, CARMENES has reanalyzed 17 known planets and has discovered and confirmed 59 new planets in the vicinity of our Solar Systemcontributing notably to expanding the census of nearby exoplanets”, he explained in the presentation of the resultss Ignasi Ribas, lead author of the study, researcher at ICE-CSIC and director of the Institute of Spatial Studies of Catalonia.
The telescope has detected 6 ‘Jupiter-like’ planets (with masses more than 50 times that of the Earth), 10 ‘Neptunes’ (from 10 to 50 Earth masses) and 43 Earths and super-Earths (Up to 10 Earth masses, scientists have detailed.

Although they are located at a distance of thousands of years that makes displacement from Earth impossible in current times due to technology, scientists consider that it is a beneficial contribution for the future of humanity by having begun a more precise tracking of the universe. In addition, CARMENES offers new data on the atmospheres of stars and planetss glimpsed, which can give clues to indicate if there is life on other planets or if biological development is possible in them.
However, this advance does not stop here because the experts are going to deepen and adjust the map of the universe thanks to this tool. “In order to determine the existence of planets around a star, we observe it a minimum of 50 times. Although the first round of data has already been published so that the scientific community can access them, these series of observations have not yet concluded“, has anticipated the researcher Juan Carlos Morales, one of the study firms.
