A number of important scientific and astronomical events have characterized 2013. Among them would be the discovery of numerous extra solar planets similar to Earth and a number of galaxies, comets and asteroids that have intrigued the experts for the interesting aspects of a scientific level. Astronomers, therefore, have come a year basically full of
Discovery of the first exo-moon could harbor life

It was identified the first moon outside our solar system. The existence of exo-moons were known for some time. And the odds that they can sustain life are high. However, up to now at least, there were no reports supporting the existence of life. And that just would discover at a distance of 1,800 light

It was scheduled for eight zero nine hours of Europe, Sunday, December 29th, the closest approach ever to Phobos. Touching upon the surface, the European probe Mars Express collected basic data on the origin of the enigmatic larger of the two Martian moons. Image source: www.jpl.nasa.gov Just 45 km away. That was the distance that

The unusually flat spectrum detected by Hubble’s for two extrasolar planets of the most common type, both with a mass similar to that of Neptune, leads scientists to hypothesize the presence of clouds at high altitude in their atmospheres. The two studies can be read in Nature. The size of GJ 436b and GJ 1214b
