Café & Kosmos 12 July 2011
30 June 2011: The exploration of the Universe using radio waves is an exciting research area that has been in continuous development since the mid-20th century. ALMA, a new radio observatory, is being built at an altitude of over 5000 metres in the Atacama Desert in Chile. It will eventually include 66 individual telescopes, working together to collect submillimetre and millimetre radio waves. What are these waves from outer space? Why are they useful for observing the cosmos? Wolfgang Wild, the European ALMA Project Manager from ESO will answer these questions, as well as those from the audience of the Café & Kosmos. 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 the second Tuesday of each month at the Vereinsheim, in Munich (please note the change of day and venue, ...

ESOcast 32: Most Distant Quasar Found
29 June 2011: Quasars are extraordinarily bright distant galaxies that are thought to be powered by vast black holes at their centres. Now, a team of European astronomers has used ESO’s Very Large Telescope, and a host of other telescopes, to find the most distant of these brilliant beacons ever recorded — it is so far away that it took 12.9 billion years for its light to reach us.In this ESOcast, Dr J explains how astronomers spent five years painstakingly searching for this object, and how its properties can help us understand the early Universe.Check out more episodes of the ESOcast here.

ESOcast 31: Pandora's Cluster
22 June 2011: Galaxy clusters contain literally trillions of stars, and when these massive structures collide all manner of strange effects occur. Using ESO’s Very Large Telescope and a number of other top quality detectors, astronomers have been studying the colliding galaxy cluster Abell 2744, nicknamed Pandora’s Cluster because of the many strange phenomena taking place there. In this episode of the ESOcast join Dr J as we piece together the violent and complex history of Pandora’s Cluster, one of the strangest colliding clusters in the sky.

ESO’s New Compact Laser Guide Star Unit Tested
22 June 2011: Last night, ESO’s Wendelstein laser guide star unit had its first light at the Allgäu Public Observatory in Ottobeuren, Germany. Laser guide stars are artificial stars created high up in the Earth’s atmosphere using a laser beam with a power of several watts. The laser, in this case a powerful 20 watt yellow beam (operating at 589 nm), makes the sodium atoms in a layer 90 kilometres up in the atmosphere glow and so creates an artificial star in the sky that can be observed by a telescope. The adaptive optics equipment can then use measurements of the artificial star to correct for the blurring effect of the atmosphere in the observations.ESO has developed a concept for compact laser guide star units, whereby small powerful lasers are combined with a telescope that launches the beam, creating a single modular unit that can be mounted directly on a large telescope. This ...

Alan Moorwood, 1945–2011
20 June 2011: Dr. Alan Moorwood, the longest serving astronomer at ESO until his retirement in May 2010, died on Saturday 18 June 2011, after a short and incurable illness. Alan Moorwood, born in May 1945, was educated in the United Kingdom. After a few years at ESA, he joined ESO as an infrared astronomer on 1 October 1978, when the Organisation was still based in Geneva. During an exemplary career at ESO, spanning more than three decades, Moorwood pioneered the development of infrared instrumentation for La Silla and co-authored the Very Large Telescope (VLT) instrumentation plan. He oversaw ESO’s entire instrumentation effort while at the same time maintaining a very active research programme resulting in nearly 400 publications, making him one of ESO’s most-cited astronomers. Moorwood’s research centred on using infrared imaging and spectroscopy obtained with space observatories and ground-based telescopes to understand star formation in galaxies, including the study of molecular ...

ESO Moves One Step Closer to the First Extremely Large Telescope
15 June 2011: With a decision by ESO Council to endorse a revised baseline design for the E-ELT, ESO is one step closer to starting construction of the European Extremely Large Telescope (E-ELT) on 3060-metre-high Cerro Armazones near ESO’s Very Large Telescope site in Chile. After the successful E-ELT Design Review in September 2010 and with Brazil joining ESO (eso1050), the E-ELT project is now not only technically ready to enter the construction phase, but is also backed by a solid funding scenario.Between the end of 2010 and the summer 2011, the E-ELT project extended the detailed design phase in order to consider the recommendations of the E-ELT Design Review. The main goals were the reduction of risk by optimising the cost and constraining the schedule to make sure that ESO can further expand its leading role in astronomy by constructing the world’s first extremely large telescope.In June 2011, the ESO Council endorsed ...

ESOcast 30: First Images from the VLT Survey Telescope
8 June 2011: This ESOcast introduces the VLT Survey Telescope (VST), the latest addition to ESO’s Paranal Observatory. This new telescope has just made its first release of impressive images of the southern sky. The VST is a state-of-the-art 2.6-metre telescope, with the huge 268-megapixel camera OmegaCAM at its heart. It is designed to map the sky both quickly and with very fine image quality. It is a visible-light telescope that perfectly complements ESO’s VISTA infrared survey telescope. Strikingly detailed images of the Omega Nebula and the globular cluster Omega Centauri demonstrate the VST’s power.

VLT's Interferometer Goes Deeper
6 June 2011: On the nights of 15–17 May 2011, astronomers successfully applied a new observing technique on ESO’s Very Large Telescope Interferometer (VLTI). The new procedure is called “blind observation mode” and will allow interferometric observations to be made of targets significantly fainter than before. It has already produced detailed observations of the spectrum of a quasar, 10 times fainter than the best currently known results. The result was obtained by combining the light from three of the VLT’s 8.2-metre Unit Telescopes in the AMBER [1] beam combiner. The ground-breaking technique, developed by a team of astronomers led by Romain Petrov from the Laboratoire Fizeau (Université de Nice, Observatoire de la Côte d’Azur and CNRS, France), allows them to observe targets that would ordinarily be far too faint to be detected by an interferometer. They do this by first observing a bright star near the faint target, which allows them to calibrate ...

ESOcast 29: Running a Desert Town
12 May 2011: The Cerro Paranal site was chosen to host ESO’s flagship telescope, the VLT, because it is one of the driest and most remote places on Earth. This may make for excellent observing conditions, but the desert is a hostile environment. Water and vegetation are virtually non-existent, not to mention the lack of modern amenities such as power. How is it possible to run such advanced technology in this barren environment? And how does the site manage to support the staff and visitors at the Paranal Residencia? This episode of the ESOcast takes us behind the scenes of the Paranal Observatory and shows us how they overcome the immense challenges of life in the Atacama Desert.

Café & Kosmos 10 May 2011
3 May 2011: Black holes are probably the most exotic objects in astronomy: they are the most compact objects the Universe has to offer, they bend space and time and they hurl jets of matter out into the vastness of space at almost the speed of light. It is also interesting to consider the celestial objects associated with black holes: X-ray binaries, gamma-ray bursts, quasars and blazars. It is no wonder that they haunt the imaginations of science fiction authors. Black holes also play an important role in astrophysics; their influence on the formation and evolution of stars and galaxies has only become clear in recent decades. But can the existence of these extraordinary objects be explained? This and other fascinating questions will be addressed during the next Café & Kosmos on Tuesday, 10 May 2011, at 19:00, by the astrophysicist Andreas Müller (Excellence Cluster Universe, & TUM), who has been studying black ...

Superb New Mirrors Bring Exoplanet Discoveries Nearer
28 April 2011: Three unique and remarkably perfect toric mirrors, which are a vital component for SPHERE, a new instrument at the VLT, have been successfully completed and tested. SPHERE is one of the second generation of VLT instruments and it will search for giant Jupiter-sized exoplanets orbiting nearby stars, using direct imaging. The mirrors were manufactured for SPHERE at the Laboratoire d’Astrophysique de Marseille (LAM) in France. The mirrors are called toric because their surfaces have slightly different curvatures in different directions — like the surface of a large torus, or doughnut. Directly detecting exoplanets is one of the most exciting areas of modern astronomy, but it is also undoubtedly one of the most challenging. Sometimes likened to trying to spot a firefly against the overwhelming light of the Moon; the enormous contrast in brightness between the host star and the orbiting planets means that an extraordinarily sensitive and precise instrument is ...

Spinstars: The First Polluters of the Universe?
27 April 2011: By studying some of the oldest stars in our galaxy, an international team of astronomers led by Cristina Chiappini [1] has used data from ESO’s Very Large Telescope to show that the first massive stars in the Universe were probably very fast rotators, which they have dubbed spinstars. Their findings will be published in an article in Nature on 28 April 2011. Massive stars live fast and die young, so the first generation of massive stars in the Universe is already dead. However, their chemical imprint, left behind like an incriminating fingerprint, can still be found today in the oldest stars in the Milky Way. These fossil records provide valuable clues about the mysterious first stellar generation to enrich the pristine early Universe. Soon after the Big Bang, the Universe was made almost entirely of hydrogen and helium. It was only enriched with other elements around 300 million years later ...
