Studying red giant stars tells astronomers about the future of the Sun and about how previous generations of stars spread the elements needed for life across the Universe. One of the most famous red giants in the sky is called Mira and lies about 400 light-years from Earth. Sofia Ramstedt is leading an international project to study binary red giant stars with ALMA and Mira is part of that study. The new high-resolution images reveal the close interaction between Mira and its companion. Despite their rather large separation, the two stars have had a strong effect on one another and the new images demonstrate how double stars can influence their environments and leave clues for what will be their future fate.
The image has been selected as ESO’s picture of the week:
The International Commission on Physics Education is pleased to announce that the winner of the 2014 ICPE Medal for outstanding contributions to physics education is Professor Cedric Linder of Uppsala University, Sweden.
The award recognizes Professor Linder's outstanding contributions to physics education research. His work has been notable for its range, depth and impact, as well for its international scope. Educated at universities in South Africa, the USA and Canada, Cedric Linder, in 1996, was awarded the first personal Chair in Physics Education in South Africa. He moved to Uppsala University in 2000, becoming the first Professor of Physics Education Research in Sweden, while still retaining his professorship at the University of the Western Cape.
Active Galactic Nuclei (AGN) are fuelled by super-massive black holes residing in their centres, making them the most luminous (now extinct) galaxies in the universe. As part of her PhD thesis, Beatriz Villarroel has studied neighbours to two major types of AGN, to gain more insight into similarities and differences between theses types. According to a geometrical unification theory dating back to the 1980s, these two types are intrinsically similar objects, observed from different viewing angles (Type-1: pole-on; Type-2: edge-on). The present work identifies systematic differences in neighbours to Type-1 and Type-2 AGN, clearly showing that there are environmental (thus likely evolutionary) circumstances that influence the appearance of the AGN phenomenon.

After seven years of preparation, the ESA cornerstone mission Gaia was successfully launched from French Guyana at 1012 h (CET) on the 19th of December. It is now on its way to Lagrange point 2, 1.5 million kilometers outside Earth's orbit.
Several scientists from the Department of Physics and Astronomy have had active roles in the Gaia Data Processing and Analysis Consortium (DPAC), a team of some 400 scientists around Europe which has prepared the software side of the mission. Soon, this software will be put to the test on actual Gaia data. This moment is of course anxiously awaited.
