An interstellar mystery of why stars form has been solved thanks to the most realistic supercomputer simulations of galaxies yet made. Theoretical astrophysicists found that stellar activity - like supernova explosions or even just starlight - plays a big part in the formation of other stars and the growth of galaxies.
First measurements by the Rosetta mission's ROSINA instrument show that the deuterium-to-hydrogen (D/H) ratio of the comet 67P/Churyumov-Gerasimenko is highly enriched in deuterium. These results contradict the theory that the water present in the Earth's atmosphere and oceans has a cometary origin.
Scientists have picked up an atypical photon emission in X-rays coming from space, and say it could be evidence for the existence of a particle of dark matter. If confirmed, it could open up new perspectives in cosmology.
With the Atacama Large Millimeter/submillimeter Array (ALMA) observation, astronomers found spiral arms of molecular gas and dust around the 'baby twin' stars, binary protostars. Gas motions to supply materials to the twin were also identified.
In 2012 the Mars Science Laboratory landed in the fascinating Gale crater. The Gale crater is of such great interest because of the 5.5 km high mountain of layered materials in the middle. This material tells an intricate story of the history of Mars, perhaps spanning much of the existence of this mysterious planet.
The BAE Systems initiative seeks to find energy-saving and maximising solutions to enable eco-friendly aircraft to stay in space for long periods of time without the need to return to earth to re-fuel or to avoid carrying vast amounts of heavy fuel on long-stay journeys.
