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 ...

First Complete Set of Detectors for ALMA Delivered to ESO

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 ...

Café & Kosmos 21 December 2011

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, ...

Ten Years of VLT Adaptive Optics

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 ...

Café & Kosmos 8 November 2011

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 ...

ESOcast 38: Faraway Eris is Pluto's Twin

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.

ESO Astronomer Awarded Chilean Medal

21 oktober 2011: In a ceremony at the Chilean Consulate General in Hamburg, Germany, the Consul General, Eduardo Schott, awarded the rank of Commander of the Order of Bernardo O’Higgins to Hans-Emil Schuster in recognition of his important contribution to astronomy in Chile. Born in 1934, Hans-Emil Schuster is a German astronomer who worked first at the Hamburg Observatory and then at the European Southern Observatory in Chile from the 1960s, before retiring in 1991. A former student of Otto Heckmann in Hamburg — the first Director General of ESO — he was appointed assistant astronomer at ESO in 1964 and was among the first staff members of the organisation. In the late 1970s and early 1980s, Mr Schuster discovered no fewer than 25 asteroids and two comets, 106P/Schuster and C/1976 D2 — which had the largest observed minimum distance to the Sun of the time, at one billion kilometres. He is also ...

Matta's Universes

19 oktober 2011: Los Universos de Matta (Matta’s Universes) is a new exhibition inaugurated at the University of Santiago (USACH) Planetarium on 13 October 2011. Inspired by the work of the multifaceted Chilean artist Roberto Matta Echaurren, this exhibition opened in the new Astronomy Park in the green area surrounding the Planetarium. Born in Santiago on 11 November 1911, Roberto Matta was a painter, an architect, a philosopher and a poet. Deeply fascinated by science and influenced by Einstein’s theory of general relativity, he introduced the concept of space-time into his artwork, as well as bringing in several other astronomical elements. This aspect of his work is illustrated in this exhibition by the large cube that hosts the images and paintings on display, and also represents the multiple dimensions of spacetime. This exhibition is part of the commemorative activities that have taken place during 2011 for the centenary of Matta’s birth. Among the ...

Café & Kosmos 11 October 2011

6 oktober 2011: Although it is invisible, and has so far never been directly detected, dark matter dominates the Universe. Without this mysterious substance the motion of stars around the centres of their galaxies cannot be explained and, even more importantly, some specialists consider that none of the structures we observe in the Universe could have formed without dark matter. Weakly Interacting Massive Particles (WIMPs) are among the best candidates to explain what dark matter may be made of. Scientists are currently conducting several experiments using different methods to try to uncover the nature of dark matter particles. Dr. Jean-Côme Lanfranchi, from the Excellence Cluster Universe (TUM) will present one of these experiments, CRESST (Cryogenic Rare Event Search with Superconducting Thermometers), to the participants at the next Café & Kosmos, on 11 October 2001. CRESST, which is located in an underground laboratory 1.3 km under the Gran Sasso mountain range in Italy, has ...
