What effect would the passage of a wandering star have in the vicinity of the Solar System? A team of scientists from the Max Planck Institute for Astronomy in Heilderberg (Germany) has calculated the possible consequences for Earth. The study has been published on arXiv.org, an online repository of Cornell University (USA) for pre-publications of scientific articles in the fields of mathematics, physics, computer science or quantitative biology.
For the first time in history, a team from NASA's Mars Science Laboratory (MSL) mission has confirmed that there are unequivocally organic compounds in the soil of the planet Mars. This discovery and all its details will be published in January 2015 in the Journal of Geophysical Researh.

As if it were the Star Trek movie saga, a team of scientists from the University of Colorado (USA) has discovered an invisible shield located about 11,500 kilometers above the Earth and whose function is none other than to block the so-called “electrons killers ”, particles that circulate at high speed around our planet and that pose a serious threat to both satellites, space systems or astronauts. The finding has been published in the journal Nature.
The waste collected by spacecraft, including the astronauts' own excrement, will have an unusual, innovative and ecological use: to be converted into fuel for spacecraft that travel from the Moon back to Earth. The new system has been developed by the Agricultural and Biological Engineering unit of the University of Florida (USA).
Despite the fame of the Perseids, this week we can enjoy the fastest meteor shower there is: the Leonids. Meteors can be seen each year between November 15 and 21; This year, the best day to observe them will be between November 16 and 18.
