While the comet 67P/Churyumov-Gerasimenko started moving away from the Sun, new studies have been published based on data collected over the past months. An article published in the journal “Geophysical Research Letters” describes the exam of the many fractures photographed after the arrival of ESA’s space probe Rosetta. Another article published in the journal “Annales Geophysicae” provides an explanation for the “song” of the comet discovered last year.

NASA invited people around the world to participate in an initiative to send your name to Mars. You just need to record some data on the page prepared by the Agency on its website to get a virtual boarding pass. All names will be recorded on a microchip that will be transported on the InSight lander, which is scheduled to be launched in March 2016 to land on Mars in September 2016.

A photograph of the galaxy NGC 428 taken by the Hubble Space Telescope shows its distorted and warped structure. Together with traces of a significant amount of stars being formed, it’s the sign of the merger between two galaxies. For this reason, its appearance could give us an idea of ​​what will happen in a few billion years to the Milky Way in its merger with Andromeda.

Planet 51 Eridani b is the first discovered using the Gemini Planet Imager (GPI), an instrument that started operating at the beginning of 2014 with the express purpose of directly detecting planets outside the solar system. This is the smallest exoplanet observed directly so far and its characteristics suggest that resembles Jupiter when it was very young. The results of this research were published in the journal “Science”.
