Tatooine worlds orbiting two suns often survive violent escapades of aging stars

more »
Planets that revolve around two suns may surprisingly survive the violent late stages of the stars' lives, according to new research. The finding is surprising because planets orbiting close to a single sun, like Mercury and Venus in our solar system, would be destroyed when the aging star swells into a red giant.

How this Martian moon became the 'Death Star'

more »
Researchers have demonstrated for the first time how an asteroid or comet could have caused a mega crater on Mars' largest moon Phobos -- which resembles the Death Star from the film "Star Wars" -- without completely destroying the satellite.

The Milky Way's ancient heart: VISTA finds remains of archaic globular star cluster

more »
Ancient stars, of a type known as RR Lyrae, have been discovered in the centre of the Milky Way for the first time, using ESO’s infrared VISTA telescope. RR Lyrae stars typically reside in ancient stellar populations over 10 billion years old. Their discovery suggests that the bulging centre of the Milky Way likely grew through the merging of primordial star clusters. These stars may even be the remains of the most massive and oldest surviving star cluster of the entire Milky Way.

New kind of supercapacitor made without carbon

more »
Energy storage devices called supercapacitors have become a hot area of research, in part because they can be charged rapidly and deliver intense bursts of power. However, all supercapacitors currently use components made of carbon, which require high temperatures and harsh chemicals to produce. Now researchers have for the first time developed a supercapacitor that uses no conductive carbon at all, and that could potentially produce more power than existing versions of this technology.

ARTS AT CERN announces three new open calls for artists

Today, ARTS AT CERN has launched three new open calls, giving artists the chance to conduct research at CERN as part of its COLLIDE and ACCELERATE residencies.

Under the ACCELERATE programme, ARTS AT CERN will invite a South Korean visual artist and a Croatian artist to come to CERN and learn the scientific approach for understanding our universe, while the open call for COLLIDE Pro Helvetia goes to artists who were born, live or work in Switzerland, and work in the discipline of interactive digital art. The winning artist will take part in a three-month residency where creative collisions between arts and science are thriving.  

“Science, arts and technology are key disciplines in understanding and shaping today’s culture. CERN is proud to be part of that movement, by collaborating with international institutions to foster interactions between our scientists and artists from around the globe,” said CERN Director for International Relations, Charlotte Warakaulle.

What to expect from Schiaparelli’s camera

more »

As the ExoMars Schiaparelli module descends onto Mars on 19 October it will capture 15 images of the approaching surface. Scientists have simulated the view we can expect to see from the descent camera.
