An international team of scientists has discovered two planets similar to the earth, with optimal conditions to house life. Both are temperate similar and may have liquid water on the surface.
The finding, led by scientists from the University of Göttingen (Germany), has been possible thanks to CARMENES. This is a Spanish-German project that searches for planets around nearby stars.
In addition, researchers have been able to study in great detail the Star of Teegarden, located 12.5 light years from our Solar System. This was possible thanks to CARMENES and the images obtained by the Telescopi Joan Oró-Montsec / IEEC and the Sierra Nevada Observatory.
To find the star, scientists used the Doppler technique, designed to discover planets that can not be observed directly.
Doppler measurements of the Teegarden star have shown the presence of at least two signals, identified as the planets Teegarden b and Teegarden c.
Teegarden c is in the middle of the habitable zone. This means that its surface temperature is between zero and 100 degrees. What is more, there could be water on the surface.
Of what there is no doubt is that the two planets are among the best candidates to house life.
