19 januari 2012: Earlier today, the Royal Swedish Academy of Sciences awarded the 2012 Crafoord Prize in Astronomy to Reinhard Genzel and Andrea Ghez for their separate work on proving the existence of the supermassive black hole at the centre of our galaxy. German astronomer Reinhard Genzel is director of the Max Planck Institute for Extraterrestrial Physics, located in Garching on the same campus as ESO’s headquarters. His team has been involved in an unprecedented 20-year-long study of the movement of stars around the galactic centre, which is based on observations made with ESO’s New Technology Telescope at La Silla as well as ESO’s Very Large Telescope on Paranal. The tracking of the orbits of these stars over many years has enabled astronomers to provide the strongest evidence yet of the presence of a supermassive black hole at the centre of our galaxy, as evidenced by the tight orbits of the stars due ...

18 januari 2012: The New York Times has included the Back in Time app developed by the company Landka among its Top 10 iPad apps in 2011. ESO went into partnership with Landka to deliver content for this educational app, which is an animated history e-book that guides the reader through time from the first moments of the Universe’s history until the most recent events. ESO contributed images and animations for the first four chapters: The Big Bang, The First Stars, The Milky Way and The Solar System.According to The New York Times: “The coolest history textbook you’ll find on the iPad, Back in Time tells the story of the Universe using a 24-hour clock, where the Big Bang starts the day and humans appear in the final seconds.”An intuitive interface allows the user to scroll quickly through time, entering any major event in the history of our civilisation. Each event is documented ...

16 januari 2012: This episode of the ESOcast looks at one of the key discoveries in physics made by astronomers in the past two decades: that our Universe is not only expanding, but that this expansion is also speeding up. Observations from ESO’s telescopes in Chile played a significant role in this revolutionary discovery, and scientists Saul Perlmutter (Lawrence Berkeley National Laboratory and University of California, Berkeley, USA), Brian P. Schmidt (Australian National University), and Adam G. Riess (STScI, Baltimore, USA) were awarded the 2011 Nobel Prize in Physics for the find. Two of the follow-up projects were led by ESO staff members, Chris Lidman and Bruno Leibundgut, and other ESO staff members, Isobel Hook and Jason Spyromilio, were contributors to crucial papers. By observing exploding stars known as Type Ia supernovae, teams led by the Nobel laureates established that the expansion of the Universe was not slowing down, as had been expected ...

9 januari 2012: with Prof. Jochen Schieck, Excellence Cluster Universe The Standard Model of particle physics is one of the best-validated models in physics today. Nevertheless, this model fails to account for some observed phenomena, such as dark matter, or the fact that there is no longer any antimatter in the Universe. With particle accelerators, scientists are trying to recreate the conditions in the early Universe and attempt to tackle these open questions. At Café & Kosmos on 10 January 2012, Professor Jochen Schieck (Excellence Cluster Universe) will describe two new accelerators before discussing their collision experiments: the Large Hadron Collider (LHC) at CERN and the new Super KEKB accelerator, which will start up in 2014, from the Japanese High Energy Accelerator Research Organisation, KEK. While the experiments at the LHC are tuned for very high energies, the physicists are adjusting the "newcomer" Super KEKB for maximum precision. Jochen Schieck will discuss with ...

5 januari 2012: On 1 January 2012, European radio astronomy entered a new era with the implementation of RadioNet3, the third iteration of RadioNet, the European radio astronomy collaboration. As the recognised European body for radio astronomy, RadioNet aims at facilitating access to leading radio astronomy facilities around the world for European radio astronomers. The European Commission recently secured the project by granting it 9.5 million euros for the period 2012–2015. The Max-Planck Institute for Radio Astronomy (MPIfR) will work with 24 European partner institutions, as well as South Korea, Australia and South Africa, to offer access to all 18 existing radio astronomy facilities in Europe. The project will also take full advantage of the APEX telescope operated by ESO, as well as the recently opened Atacama Large Millimeter/submillimeter Array (ALMA) of which ESO is a partner, both located in Chile. By promoting cooperation and making use of state-of-the-art facilities around the world, ...

21 december 2011: ALMA, the Atacama Large Millimeter/submillimeter Array, will soon have its own “hotel” for the astronomers, engineers, and other staff working at the observatory. The European Southern Observatory (ESO) — the European partner in ALMA — is providing the accommodation and living complex for the project, and has just signed a contract for the detailed design with the Finnish architects Kouvo & Partanen. The hotel residence will be built at 2900 metres above sea level, at the ALMA Operations Support Facility in the Atacama Desert, in the foothills of the Chilean Andes. The design phase is planned to last six months, followed by the procurement actions for the construction. Completion of construction is expected in 2014. The buildings’ architectural design will be integrated into the landscape by using local materials such as stone, copper and volcanic rock. Their facades and structures will use the colours and tones of the surroundings, and ...

21 december 2011: The Chilean Engineers Association awarded the National Prize 2011 to the European Southern Observatory (ESO), in the category of institutions, for its valuable contribution to engineering development in Chile. On behalf of ESO, the Representative in Chile, Massimo Tarenghi, received a medal and a diploma during a ceremony held on 11 October 2011. In the category of professional of the year, the prize was awarded to the Chilean engineer Santiago Arias Soto, a global expert on seismic structural design.This prize has been awarded every year since 1992, to the engineer or institution that excels in the construction of complex civil works and contributes to the development of Chile with challenging projects, technological transfer to and from the country, high standards of environmental protection and an active role for Chilean engineering.

21 december 2011: The European Southern Observatory (ESO) has just taken delivery of the last of a set of 73 state-of-the-art extremely sensitive detectors for the Atacama Large Millimeter/submillimeter Array (ALMA) project, from NOVA (the Netherlands Research School for Astronomy). When complete, ALMA will consist of 66 large antennas, operating as a single telescope. It will observe the Universe in light with wavelengths around one millimetre or less — very short wavelength radio waves. To do this, each of the antennas must be equipped with an arsenal of detectors, like highly sensitive radio receivers, operating in different wavelength bands. The receivers, which are being made by institutes in Europe, North America, and Japan, must be cooled to temperatures of -269 degrees Celsius in order to detect the faint signals from space. The so-called “Band 9” receivers are the second-shortest wavelength ALMA detectors, detecting light with wavelengths as short as 420µm (0.42 millimetres). The ...

16 december 2011: with Dr Hubertus Thomas, Max-Planck Institute for Extraterrestrial Physics On 21 December 2011 Café & Kosmos goes to the International Space Station! There, scientists perform many different experiments, including those on plasma crystal research, about which Dr. Hubertus Thomas (MPE) will speak this evening, bringing the Café & Kosmos visitors and the ISS closer. A plasma is an ionised gas, which is, after the solid, liquid and gaseous states, a fourth state of matter. Therefore, a plasma crystal is in itself an impossible state of matter! Crystallisation in a plasma is only possible with the addition of "dust". But then the scientists can distinguish separate particles, ie individual "atoms", and dynamically monitor processes such as melting, or investigate directly the motion of lattice defects. Since the particles are about one thousandth of a millimetre in size, gravity plays a major role in the generation of plasma crystals. In the laboratory, ...

14 december 2011: This episode of the ESOcast looks at exciting new observations of a mysterious object that is a favoured theme in science fiction: the black hole. But the science fiction is fast becoming science fact, and the ending won’t be a happy one for the black hole’s victim. Astronomers using ESO’s Very Large Telescope have discovered a gas cloud with several times the mass of the Earth accelerating fast towards the black hole at the centre of the Milky Way. This is the first time ever that the approach of such a doomed cloud to a supermassive black hole has been observed. Watch the episode to learn more about how astronomers discovered this cloud, and what is going to happen to it over the next few years. More Information The ESOcast is a video podcast series dedicated to bringing you the latest news and research from ESO — the European Southern ...

13 december 2011: Click here for a special seasonal greeting from everyone at the European Southern Observatory! The year 2011 has been yet another fruitful year for ESO. The organisation saw a number of significant steps forward in its mission to build and operate world-class ground-based telescopes. In June, a new state-of-the-art telescope, the VLT Survey Telescope (VST), had its first light at the Paranal Observatory (eso1119). The telescope is equipped with an incredible 268-megapixel camera designed to map the sky in visible light. Another major milestone was the start of early science operations with the Atacama Large Millimeter/submillimeter Array (ALMA) at the end of September, which we celebrated with our partners in the global ALMA collaboration in North America and East Asia, and with the Republic of Chile. This was marked by a stunning first public image from ALMA, showing the famous Antennae Galaxies (eso1137). Additionally, with the Republic of Chile’s donation ...

25 november 2011: 25 November 2011 marks the 10th anniversary of NACO, the first adaptive optics system to be installed on the ESO Very Large Telescope (VLT). NACO’s ultra-sharp vision has greatly contributed to the major discoveries made with the VLT. NACO, short for NAOS-CONICA, was the first adaptive optics instrument to be installed on the VLT, in 2001 (eso0137). By compensating for turbulence in the Earth’s atmosphere, NACO greatly improved the telescope’s image sharpness and scientific potential. The instrument, developed by French and German consortia with the collaboration of ESO, was the first of a series of adaptive optics instruments that would be installed on the VLT Unit Telescopes. Some of NACO’s first targets were planets and moons in the Solar System. These observations provided the first detailed maps of Titan’s weather and surface (eso0505) and infrared images of Io’s powerful volcanoes (eso0204). NACO has also observed planets orbiting other stars. In ...

7 november 2011: Colliding and exploding stars, which we witness as supernovae and gamma-ray bursts, generate the most powerful and brightest surges of energy in the Universe. During the very short time needed for these explosions to produce a neutron star or a black hole, they release more energy than the Sun during its whole life. Their observations, billions of light-years away, give us direct insights on the accelerated expansion of the cosmos. As destructive as these explosions are, they nevertheless play an important role in the evolution of their host galaxy. Without them, there would be no planets, no plants, no animals. The explosions drive the cycle of matter in the galaxy: the chemical elements heavier than hydrogen and helium, produced by previous generations of stars and supernovae, are dispersed into space by these stellar explosions, so they can be incorporated into new stars and condense into planetary systems. The astrophysicist Hans-Thomas ...

26 oktober 2011: Astronomers have accurately measured the diameter of the faraway dwarf planet Eris for the first time by catching it as it passed in front of a faint star. This event was seen at the end of 2010 by telescopes in Chile, including the Belgian TRAPPIST telescope at ESO’s La Silla Observatory. The observations show that Eris is an almost perfect twin of Pluto in size. Eris appears to have a very reflective surface, suggesting that it is uniformly covered in a thin layer of ice, probably a frozen atmosphere. This ESOcast takes a look at the clever technique that the astronomers used and what they have found out about Eris.
