2 februari 2011: After our recent discussion about dark matter, the Café & Kosmos will now concentrate on the other invisible component of the Universe, the dark energy. With its share of 73 percent of the total energy budget, the dark energy dominates the Universe. It is the driving force that causes it to expand faster and faster. The discovery of this accelerated expansion dates back to 1998; it is still a fairly young field of investigation.In his research, Prof. Stefan Hofmann (Excellence Cluster Universe) investigates the question of how the dark energy fits into existing physical models. The cosmologist will expose various scenarios: is the model by Einstein satisfactory, with a cosmological constant or a vacuum energy, or should the scientists consider an alternative theory of the gravitation to explain the physics of the very large distances in the Universe? He will discuss the implications with the Café & Kosmos guests. The ...

1 februari 2011: The barren landscape surrounding the Paranal Observatory in Chile is stunning, but for the ESO staff who work there, on-site recreational activities are important for entertainment and general wellbeing.

26 januari 2011: The ESO Very Large Telescope Interferometer (VLTI) has made its first observations that combine super-sharp imaging with measurements of motion. New pioneering data from the VLTI/AMBER instrument not only show extremely fine details of the gas and dust disc surrounding the brilliant supergiant star HD 62623, but also, by using spectroscopy, reveal the motions of the material in the disc for the first time. The origin of this disc has been a mystery, as such a bright star, which is near to the end of its life, is expected to blow away the material surrounding it, and not to be surrounded by a dusty disc similar to those around very young stars. A team of astronomers led by Florentin Millour (Observatoire de la Côte d’Azur, Nice) has now found that the material is orbiting the star — just as the planets in the Solar System orbit the Sun. Surprisingly they ...

7 januari 2011: Articles include an overview of how Disney Television Italy worked alongside the Education and Public Outreach office of the INAF Astronomical Observatory of Padua in Italy to help promote astronomy to children. The authors discuss the differences between the working practices of an entertainment company and an astronomical observatory, and how these were overcome to form a successful partnership. This issue also tackles some difficult topics in science communication, such as the problems encountered when explaining complex scientific theories to a general audience and the misperceptions that can arise as a result, and how well the public interprets astronomical images. Also in this issue, how new and existing tools can be used by science communicators, including a look at the Virtual Observatory, which is an international project that provides an infrastructure for sharing vast amounts of astronomical data online. And how microblogging sites such as Twitter can be much more ...

20 december 2010: The closure of the IYA2009 Secretariat marks the end of the largest project that the International Astronomical Union (IAU) has ever embarked upon. In July 2007, the International Astronomical Union (IAU) established the IYA2009 Secretariat at the European Southern Observatory’s (ESO) Headquarters in Garching, Germany. The Secretariat’s role was to act as a hub for IYA2009 activities. It coordinated projects from the planning stages through to evaluation, and was a central contact and resource centre for the hundreds of national nodes, international organisations, global projects, the media and the general public. The Secretariat was embedded in ESO’s education and Public Outreach Department, which provided invaluable support and expertise for IYA2009. The IYA2009 was a huge success, involving 148 countries around the world organising hundreds of thousands of individual activities reaching hundreds of millions of people. Feedback has been extremely positive. The impact of IYA2009 on the scientific literacy of the ...

17 december 2010: The Space Telescope European Coordinating Facility, a unique collaboration between the European Space Agency (ESA) and the European Southern Observatory, will close on 31 December 2010 after 26 years. ESA’s continuing partnership with NASA on the Hubble mission ensures that European astronomers will continue to have access to observing time. The Space Telescope European Coordinating Facility (ST-ECF), the scientific and technical co-ordination centre for the Hubble Space Telescope in Europe, will close its doors at the end of December 2010. This is part of a process in which the European Space Agency is streamlining its operations and concentrating astronomical operations, archiving and data reduction expertise at its European Space Astronomy Centre (ESAC) in Spain. The ST-ECF was formed in 1984, six years before Hubble’s launch, as a key plank in ESA’s partnership with NASA and as a vital element in maximising Europe’s scientific return in the pre-internet age. Rather than ...

16 december 2010: Gamma-ray bursts are the most powerful explosions in the Universe and are thought to follow cataclysmic events, such as the collapse of a massive star. But to observe these fleeting events, astronomers need to be lightning quick. In this episode of the ESOcast, Dr. J explains how the VLT’s Rapid Response Mode makes it possible to observe gamma-ray bursts within minutes of detection by space-based telescopes. More episodes of the ESOcast are also available. Credits Visual design and editing: Martin Kornmesser and Luis Calçada. Editing: Herbert Zodet.

15 december 2010: The world’s most sensitive receiver for radio waves with wavelengths around 1.5 millimetres has been delivered to ESO. Its final destination is the Atacama Large Millimeter/submillimeter Array (ALMA), which is under construction 5000 metres above sea level in northern Chile, on the Chajnantor plateau. ALMA, the largest astronomical project in existence, is a partnership of Europe, North America and East Asia in cooperation with the Republic of Chile, and ESO is the European partner in ALMA. The receiver — operating in a wavelength range known as Band 5 at ALMA — will allow scientists to trace water vapour in the nearby Universe, and will also provide an unprecedented view of the most distant galaxies. The delivery is an important milestone for the project for ALMA Enhancement of Early Science, funded by the 6th Framework Programme of the European Commission. The project has developed new technologies from scratch in just five ...

8 december 2010: Click here for a special seasonal greeting from everyone at the European Southern Observatory! This year has heralded many new discoveries, facilitated by the ESO telescopes, including the thought-provoking find of a distant planetary system that resembles the Solar System. Using the HARPS spectrograph attached to ESO’s 3.6-metre telescope at La Silla in Chile, astronomers detected up to seven planets in orbit around a Sun-like star (eso1035). And an unusual interloper — an exoplanet that entered the Milky Way from another galaxy — was found by a European team of astronomers using the MPG/ESO 2.2-metre telescope at La Silla (eso1045). In 2010 astronomers went far beyond just discovering such distant worlds. Amongst many new findings, astronomers used ESO’s Very Large Telescope at the Paranal Observatory in the Atacama Desert, Chile, to detect the first spectrum of an exoplanet (eso1002) directly and to analyse, for the first time, the atmosphere of ...

2 december 2010: The Universe contains a dark secret: most of the matter, whose presence is revealed by its gravitational effect, does not emit or absorb any light. Today, we have good reasons to assume this “dark matter” is made of a new type of elementary particle that interacts only very weakly with the light and with ordinary matter. For the past 25 years, we have explored different strategies to bring light into this darkness, and to elucidate the physical nature of dark matter. During the next Café & Kosmos, Dr. Georg Raffelt (Max-Planck Institute for Physics) will explain the justifications for the existence of dark matter, mention candidates from particle physics, and discuss possible strategies to search experimentally for dark matter. The Café & Kosmos series of discussions is organised jointly by ESO, the Excellence Cluster Universe and the Max-Planck Institutes for Physics, Astrophysics and Extraterrestrial Physics. The discussions take place on ...

2 december 2010: Professor Adriaan Blaauw, the European Southern Observatory’s second Director General, and a key figure in ESO’s early history, died yesterday, 1 December 2010, at the age of 96. “Adriaan Blaauw was one of the most influential astronomers of the twentieth century. I had the privilege to be amongst his students when he returned to Leiden from his position as Director General. He continued to remain keenly interested in everything to do with ESO, and still had his characteristic twinkle in the eye when he visited La Silla and Paranal earlier this year. It is hard to grasp that he is no longer with us,” said ESO’s current Director General, Professor Tim de Zeeuw. Adriaan Blaauw was born in Amsterdam, the Netherlands, in 1914. He studied astronomy at Leiden University, under de Sitter, Hertzsprung and Oort, and obtained his doctorate with van Rhijn at the Kapteyn Laboratory in Groningen in 1946, ...

26 november 2010: The brochure, called the International Year of Astronomy 2009 Final Report Executive Summary, offers an overview of the many events that took place during the Year, as detailed in full in the 1450-page IYA2009 Final Report, which was released earlier this year. “Tens of thousands of events were held during IYA2009, but unfortunately there is only space in this Executive Summary to mention a small handful,” says Catherine Cesarsky, chair of the IYA2009 Working Group, and the IAU President for most of IYA2009. “We’ve included a diverse cross-section of events that are representative of the Year, but they should not be viewed as a ‘best of IYA2009’. We are grateful to everyone who took part in IYA2009 and we would like to say thank you to you all." The print-ready files and source files (Adobe InDesign file and images) are also available for IYA2009 stakeholders to adapt for use in ...
