Two months after scientists Massachusetts Institute of Technology (MIT) and the University of Liege (Belgium) discovered a new planetary system, called Trasppist- 1 announced their initial findings. The principal indicates that there are two planets very similar to Earth not only for its size but for its composition. These two rocky worlds and not gaseous like most (which are much like Jupiter).
Although so far have made the first analysis, this discovery says MIT said in a statement, “ reinforces the argument that may be habitable. in addition, their atmospheres seem to be” broad and diffuse, like Jupiter, but compact, similar to that of Earth, Venus and Mars. “
according to Julian de Wit, a researcher at MIT data collected were very strong and” the observations were the best we could expect. “
the advantage of these two new planets is that they are relatively close distance (40 light years) and that allows to analyze in more detail than others found by the Kepler telescope. So, as I said Wit the newspaper El Mundo of Spain, one can say that the two most similar to Earth of all known.
Both bodies were observed through the Hubble telescope, as NASA announced a few days ago, it will be replaced in 2018 by the James Webb Space telescope (JWST), which is almost three times larger than its predecessor. Once it is running, says Wit, you can know what kind of atmosphere have planets Trasppist-1 and also will know what’s in them.
For now, there are only hypotheses suggest that these atmospheres may be formed of carbon dioxide, such as Venus; or clouds, like that of Earth; or a “poor” as Mars.
