A close-up of Comet 67P/Churyumov-Gerasimenko by NASA's ultraviolet instrument surprised scientists by revealing that electrons close to the comet's surface - not photons from the Sun as had been believed - cause the rapid breakup of water and carbon dioxide molecules spewing from the surface.
An international team has discovered a young planetary system that shares remarkable similarities to our own early solar system. Their images reveal a ring-like disk of debris surrounding a Sun-like star, in a birth environment similar to the Sun's.
Using ever more energetic lasers, researchers have produced a record high number of electron-positron pairs, opening exciting opportunities to study extreme astrophysical processes, such as black holes and gamma-ray bursts.
Astronomers have discovered for the first time a rear-end collision between two high-speed knots of ejected matter from a supermassive black hole. This discovery was made while piecing together a time-lapse movie of a plasma jet blasted from a supermassive black hole inside a galaxy, located 260 million light-years from Earth.
Astronomers have discovered a disc of planetary debris surrounding a young sun-like star that shares remarkable similarities with the Kuiper Belt that lies beyond Neptune, and may aid in understanding how our solar system developed.
Great honour for Nicolas Thomas from the University of Berne: The scientist was selected as part of the imaging team for NASA's Europa Clipper mission. The mission will help to answer the question whether there is life in the oceans of Jupiter's moon, Europa.
In the brightest region of the nebula RCW 34, gas is heated and expands through the surrounding cooler gas. Once the heated hydrogen reaches the borders of the gas cloud, it bursts outwards into the vacuum like the contents of an uncorked champagne bottle - this process is referred to as champagne flow. But the young RCW 34 has more to offer; there seem to have been multiple episodes of star formation within the same cloud.
Supernovas just might be the maid service of the universe. It seems these explosions that mark the end of a star's life work hand-in-hand with supermassive black holes to sweep out gas and shut down galaxies' star-forming factories.
