Hubble Solves Cosmic 'Whodunit' with Interstellar Forensics

Winner Declared in Tug-of-War Between Two Satellite Galaxies of the Milky Way

In a cosmic tug-of-war between two dwarf galaxies orbiting the Milky Way, only NASA’s Hubble Space Telescope can see who’s winning. The players are the Large and Small Magellanic Clouds, and as they gravitationally tug at each other, one of them has pulled out a huge amount of gas from its companion. This shredded and fragmented gas, called the Leading Arm, is being devoured by the Milky Way and feeding new star birth in our galaxy. But which dwarf galaxy is doing the pulling, and whose gas is now being feasted upon? Scientists used Hubble’s ultraviolet vision to chemically analyze the gas in the Leading Arm and determine its origin. After years of debate, we now have the answer to this “whodunit” mystery.

High-energy ions' movement affected by silicon crystal periodicity

more »
The thinner the silicon crystal, the easier it is to manipulate the trajectories of very high-energy ions in particle accelerators. Further applications include materials analysis, semiconductor doping and beam transport in large particle accelerators. All of these rely on our understanding of how positively-charged high-energy particles move through crystals.

Arts at CERN announces the winners of the Collide awards

Arts at CERN pioneers new ways of bringing together artists and scientists, leads the conversation about art and science, and supports artistic creativity and curiosity towards fundamental research. Artists from all over the world are invited, through our cultural programmes, to spend time at CERN and work alongside particle physicists and engineers.

Today, we announce the winners of Collide International and Collide Geneva. Both awards offer a fully funded residency of up to three months to one artist in each category in order to research new ideas and crossovers between artistic practice and scientific research at the largest particle laboratory in the world.

Arts at CERN aims to break down the silos between arts and science, helping us to understand the world around us from different perspectives. It enriches all of us when barriers are overcome and new knowledge is enabled. We are grateful to all the participants in Collide International and Collide Geneva for helping us towards this goal and congratulate them on their achievements,” says Charlotte Lindberg Warakaulle, CERN’s Director for International Relations.

Collide International is a three-month residency programme in collaboration with the UK’s Foundation for Art and Creative Technology (FACT) that provides a fully funded residency of up to two months at CERN and a month at FACT in Liverpool. A jury of experts in art and science selected Suzanne Treister as the winner of the international award. She will undertake a residency during spring 2018 to further develop her investigation ‘Holographic Universe’ and explore the artist’s motivations and intentions through the history of art, from cave painting to modernism and global contemporary art, including outsider and psychedelic art, passing through the art of the ancient world, the Americas, Africa, Asia, Islamic art and the European Renaissance. Taiwanese artist Yu-Chen Wang and Danish artist Lea Porsager received Honorary Mentions this year and will be invited to CERN for a short visit as Guest Artists in 2018.

The Collide Geneva award was dedicated to performance and was assigned to the artists Anne Sylvie Henchoz and Julie Lang. They will spend three months at CERN during the autumn of 2018 further developing their project ‘Space Time Energy’ around the potential analogies between the human body and particles. Collide Geneva is a partnership between Arts at CERN, the Republic and Canton of Geneva and the City of Geneva to foster research on artistic expression and fundamental research.

Today, artists from all over the world are invited to CERN, through our programmes, to explore new ideas and work alongside particle physicists and engineers. I am thrilled to provide these opportunities in this unique environment where artistic practice acquires a new dimension and understanding,” says Mónica Bello, Head of Arts at CERN.
