mxim Final Kiss of Two Stars Heading for Catastrophe, 21 October
An international team of astronomers have found the hottest and most massive double star with components so close that they touch each other. The two stars in the extreme system VFTS 352 could be heading for a dramatic end, during which the two stars either coalesce to create a single giant star, or form a binary black hole.

mxim Troben la relaci entre les pluges de cometes i asteroides i les extincions en massa, 21 October
Mass extinctions occurring over the past 260 million years were likely caused by comet and asteroid showers, scientists conclude in a new study published in Monthly Notices of the Royal Astronomical Society.


Saturn and Dione, 20 October
Saturn has many, varied moons over 60 have been discovered so far. One of the larger ones, Dione, is shown here in this image from the Cassini orbiter, pictured as it moved across the face of its parent planet.


Common Accretion across Young Stellar Objects, White Dwarfs, Black Holes and Supermassive Black Holes, 16 October
An international team of astronomers have discovered a previously unknown link between the way young stars, white dwarfs and black holes grow feeding from their surroundings.


A Cosmic Sackful of Black Coal, 14 October
The inky areas are small parts of a huge dark nebula known as the Coalsack, one of the most prominent objects of its kind visible to the unaided eye. Millions of years from now, chunks of the Coalsack will ignite, rather like its fossil fuel namesake, with the glow of many young stars.


Outbursts from a newborn star, 13 October
The object lies in the constellation of Orion (The Hunter) in a dense molecular star-forming region, not far from the famous Horsehead Nebula. In regions like this, clouds of dust and gas collapse under the force of gravity, spinning faster and faster and becoming hotter and hotter until a young star ignites at the clouds centre. Any leftover material swirling around the newborn protostar comes together to form an accretion disc that will, under the right circumstances, eventually evolve to form the base material for the creation of planets, asteroids and comets.


Cassini begins series of flybys with close-up of Saturn moon Enceladus, 13 October
Cassini spacecraft will wrap up its time in the region of Saturn's large, icy moons with a series of three close encounters with Enceladus starting Wednesday, Oct. 14. Images are expected to begin arriving one to two days after the flyby, which will provide the first opportunity for a close-up look at the north polar region of Enceladus.

A Shy Galactic Neighbour, 16 September
The Sculptor Dwarf Galaxy, pictured in this new image from the Wide Field Imager camera, installed on the 2.2-metre MPG/ESO telescope at ESO’s La Silla Observatory, is a close neighbour of our galaxy, the Milky Way. Despite their close proximity, both galaxies have very distinct histories and characters. This galaxy is much smaller and older than the Milky Way, making it a valuable subject for studying both star and galaxy formation in the early Universe. However, due to its faintness, studying this object is no easy task.

mxim Charting the Slow Death of the Universe, 10 August,
An international team of astronomers studying more than 200 000 galaxies has measured the energy generated within a large portion of space more precisely than ever before. This represents the most comprehensive assessment of the energy output of the nearby Universe. They confirm that the energy produced in a section of the Universe today is only about half what it was two billion years ago and find that this fading is occurring across all wavelengths from the ultraviolet to the far infrared. The Universe is slowly dying.

Jupiter Twin Discovered Around Solar Twin, 15 July 2015
An international group of astronomers has used the ESO 3.6-metre telescope to identify a planet just like Jupiter orbiting at the same distance from a Sun-like star, HIP 11915. According to current theories, the formation of Jupiter-mass planets plays an important role in shaping the architecture of planetary systems. The existence of a Jupiter-mass planet in a Jupiter-like orbit around a Sun-like star opens the possibility that the system of planets around this star may be similar to our own Solar System. HIP 11915 is about the same age as the Sun and, furthermore, its Sun-like composition suggests that there may also be rocky planets orbiting closer to the star.


Pluto and Charon: New Horizons’ Dynamic Duo, 9 July 2015
They’re a fascinating pair: Two icy worlds, spinning around their common center of gravity like a pair of figure skaters clasping hands. Scientists believe they were shaped by a cosmic collision billions of years ago, and yet, in many ways, they seem more like strangers than siblings.


Biggest Explosions in the Universe Powered by Strongest Magnets, 8 de July 2015
Observations from ESO’s La Silla and Paranal Observatories in Chile have for the first time demonstrated a link between a very long-lasting burst of gamma rays and an unusually bright supernova explosion. The results show that the supernova was not driven by radioactive decay, as expected, but was instead powered by the decaying super-strong magnetic fields around an exotic object called a magnetar.

mxim Hot lava flows discovered on Venus, 18 june
ESA’s Venus Express has found the best evidence yet for active volcanism on Earth’s neighbour planet. Seeing the planet’s surface is extremely difficult due to its thick atmosphere, but radar observations by previous missions to Venus have revealed it as a world covered in volcanoes and ancient lava flows.

mxim Hubble Telescope Detects ‘Sunscreen’ Layer on Distant Planet ,12 June
Hubble Space Telescope has detected a stratosphere, one of the primary layers of Earth’s atmosphere, on a massive and blazing-hot exoplanet known as WASP-33b.
The presence of a stratosphere can provide clues about the composition of a planet and how it formed. This atmospheric layer includes molecules that absorb ultraviolet and visible light, acting as a kind of “sunscreen” for the planet it surrounds. Until now, scientists were uncertain whether these molecules would be found in the atmospheres of large, extremely hot planets in other star systems.

mxim A Celestial Butterfly Emerges from its Dusty Cocoon,10 June
Some of the sharpest images ever made with ESO’s Very Large Telescope (VLT) have, for the first time, revealed what appears to be an ageing star giving birth to a butterfly-like planetary nebula. These observations of the red giant star L2 Puppis, from the ZIMPOL mode of the newly installed SPHERE instrument, also clearly showed a close companion. The dying stages of stars continue to pose astronomers with many riddles, and the origin of such bipolar nebulae, with their complex and alluring hourglass figures, doubly so. This new imaging mode means that the VLT is currently the sharpest astronomical direct imaging instrument in existence.

mxim Meteor Shower in Broad Daylight ,5 June
Earth is entering a stream of debris from an unknown comet, and this is causing one of the most intense meteor showers of the year. Ironically, most sky watchers won't notice because the shower peaks in broad daylight. We only know it's happening because a radar in Canada is picking up echoes from meteoroids streaking through the blue sky overhead. Astronomers call these meteors "Arietids" because they emerge from the constellation Aries not far from the June sun.

mxim NASA’s Hubble Finds Pluto’s Moons Tumbling in Absolute Chaos , 4 June
If you lived on one of Pluto’s moons, you might have a hard time determining when, or from which direction, the sun will rise each day. Comprehensive analysis of data from NASA’s Hubble Space Telescope shows that two of Pluto’s moons, Nix and Hydra, wobble unpredictably.

mxim Ultraviolet study reveals surprises in comet coma , 2 June

mxim The Dreadful Beauty of Medusa, 21 May
Astronomers using ESO’s Very Large Telescope in Chile have captured the most detailed image ever taken of the Medusa Nebula. As the star at the heart of this nebula made its transition into retirement, it shed its outer layers into space, forming this colourful cloud. The image foreshadows the final fate of the Sun, which will eventually also become an object of this kind

mxim The Dark Side of Star Clusters, 13 May
Observations with ESO’s Very Large Telescope in Chile have discovered a new class of “dark” globular star clusters around the giant galaxy Centaurus A. These mysterious objects look similar to normal clusters, but contain much more mass and may either harbour unexpected amounts of dark matter, or contain massive black holes — neither of which was expected nor is understood.

mxim Fresh Evidence for How Water Reached Earth Found in Asteroid Debris, 8 May
Water delivery via asteroids or comets is likely taking place in many other planetary systems, just as it happened on Earth, according to new research. The findings add further support to the possibility that water can be delivered to Earth-like planets via such bodies to create a suitable environment for the formation of life.

mxim Saturn Moon's Activity Could Be 'Curtain Eruptions', 7 May
New research using data from NASA's Cassini mission suggests most of the eruptions from Saturn's moon Enceladus might be diffuse curtains rather than discrete jets. Many features that appear to be individual jets of material erupting along the length of prominent fractures in the moon's south polar region might be phantoms created by an optical illusion, according to the new study.


mxim NASA’s New Horizons Detects Surface Features, Possible Polar Cap on Pluto, 30 April
