Final ALMA Front End Delivered
22 February 2013: The final front end for the Atacama Large Millimeter/submillimeter Array (ALMA) has been delivered to the observatory’s Operations Support Facility (OSF) in Chile, marking another milestone in the completion of the project. With one installed in each of ALMA’s 66 antennas, the front ends are the first step in a long chain of devices that receive, convert, process and record the astronomical data collected by the telescope. Each front end contains a set of extremely sensitive receivers, cooled to temperatures of just four degrees above absolute zero (-269 degrees Celsius), which detect the millimetre- and submillimetre-wavelength light that ALMA “sees”. Construction of the front ends for ALMA has been shared between the European, North American and East Asian partners in the project. Twenty-six of the total complement of 70 units were built at the European Front End Integration Centre, based at the Rutherford Appleton Laboratory (RAL) in the UK, including ...

New Laser Improves VLT’s Capabilities
21 February 2013: A new and more powerful laser has successfully completed testing at ESO’s Paranal Observatory and has been formally accepted today. This new laser source is called PARLA and forms a vital part of the Laser Guide Star Facility (LGSF) at ESO’s Very Large Telescope (VLT). The laser is used to generate an artificial star about 90 kilometres up in the atmosphere [1]. By creating and observing such a bright point of light astronomers can probe the turbulence in the layers of the atmosphere above the telescope. This information is then used to adjust deformable mirrors in real time in order to correct most of the disturbances caused by the constant movement of atmosphere and create much sharper images. The new laser will greatly improve the reliability and flexibility in operating the LGSF. It uses similar technology to that which will also be employed in the four lasers of the future ...

ESO Extends Lead as World’s Most Productive Ground-based Observatory
19 February 2013: An analysis of the number of peer-reviewed scientific papers published in 2012 using data from ESO’s telescopes and instruments has shown that ESO remains the world’s most productive ground-based observatory. More than 870 refereed papers using ESO data were published last year, a significant increase from the previous totals, and the most in ESO’s history. The number of papers using observations from ESO in 2012 was slightly ahead of those that used data from the NASA/ESA Hubble Space Telescope. About 70% of all the papers credited to ESO in 2012 employ data acquired using the Very Large Telescope (VLT)/ VLT Interferometer facilities, a fraction that has been consistently increasing over the past three years. Other facilities of the La Silla Paranal Observatory — including the survey telescope VISTA at Paranal as well as La Silla telescopes and instruments — have similar numbers to the previous year, and they alone nearly ...

Café & Kosmos 5 February 2013
31 January 2013: with Dr. Andreas Müller (Universe Cluster) Time paces our life. We plan our schedules and our whole lives using it. In contrast to space, time has only one direction. It is constantly progressing, and we can not move back in time to undo mistakes from our past. However, according to Einstein's theory of relativity, time is not as unalterable as we experience it. Worse: when studying time, we have to consider what the whole Universe is doing, and under some conditions, time might even vanish. At next Café & Kosmos on 5 February 2013, Dr. Andreas Müller (Excellence Cluster Universe), author of the book Space and Time will discuss the mysteries of time with the audience. Exceptionally, Café & Kosmos will take place on the first Tuesday of the month (instead of the second) on 5 February. Also, please note of the new venue: Café & Kosmos will take place ...

ESOcast 52: It's Raining Stars!
15 January 2013: On 14–16 December 2012, the Geminid meteor shower made a spectacular appearance over ESO's Paranal Observatory in Chile. As the meteors showered down over the site, ESO Photo Ambassador Gianluca Lombardi was ready with his camera to record the spectacle. He spent over 40 hours recording the shower. The Geminids is a shower of shooting stars appearing to emanate from within the constellation of Gemini (The Twins). This shower occurs when the Earth cuts through the orbit of an asteroid named 3200 Phaethon, which happens once each year, in December. Particles in the trail of dust along the orbit of Phaethon burn up in our atmosphere, creating the brilliant, fast-moving points of light characteristic of meteor showers. This is the second installment of Chile Chill, a type of ESOcast designed to offer a calm experience of the Chilean night sky and ESO’s observing sites, undisturbed by narration. The Very Large ...

ALMA Doubles its Power in New Phase of More Advanced Observations
8 January 2013: ALMA (the Atacama Large Millimeter/submillimeter Array) has begun a new and more advanced phase of science observations. This phase is known as Early Science Cycle 1, and will last until October 2013. The telescope’s power has been greatly increased: it will make observations with more antennas, spread over a greater distance, than ever before, and will use antennas from the Atacama Compact Array (ACA) for the first time. Although ALMA is still under construction, its first scientific operations began in 2011. This phase was known as Early Science Cycle 0. ALMA has already outperformed all other telescopes of its kind, and the unprecedented capabilities of the telescope have brought a first wave of exciting scientific results over the last year (see for example ann12101, eso1216, eso1239, and eso1248). The Cycle 0 observations started with just 16 of the telescope’s final complement of 66 antennas (which will be composed of a ...

Café & Kosmos 8 January 2013
4 January 2013: With Prof. Dr. Andreas Burkert (Universe Cluster) A gas cloud identified as G2 is rapidly moving toward the centre of the Milky Way. In 2013, it will make its closest approach to the supermassive black hole that is lurking there. The cloud has a mass a few times that of the Earth, and it is observable with the ESO Very Large Telescope in Chile. Such an observation will be extraordinary for several reasons: first, the passage of a gas cloud near — or into — a black hole has never been observed before. Also, the evolution of the cloud is expected to be very fast. Theoreticians will therefore be able to check the predictions of their models very quickly. Prof. Dr. Andreas Burkert, from the Excellence Cluster Universe, will discuss the possible fate of this cloud with the guests of the next Café & Kosmos, on 8 January 2013. Please ...

Astronomers Around the World Meet to Share ALMA Observatory First Results
17 December 2012: Astronomers from around the world have been meeting in Chile to discuss the exciting first year of scientific results from the Atacama Large Millimeter/submillimeter Array (ALMA) telescope. ALMA started Early Science operations at the end of September 2011, and the first scientific papers have recently been appearing in refereed journals. “Out of this first year of ALMA science we already have transformational results in the main ALMA science areas,” says Leonardo Testi from ESO, Chair of the Conference Scientific Organising Committee. “We now have a much better understanding of the process of planet formation around other stars. New and important results were obtained in the area of pre-biotic molecules in space, which may be linked to the origin of life. With ALMA we are starting to study in detail the chemistry of water and complex organic molecules and this is important for understanding our origins,” he added. Two hundred astronomers ...

Venus Transit Seen Reflected from the Moon
14 December 2012: On 6 June 2012 Venus passed directly between the Earth and the Sun and the planet appeared as a silhouette against the solar disc. Such a transit of Venus will not happen again until 5 December 2117. The recent transit could not be seen from ESO’s Chile observatories as the Sun was below the horizon. But, undaunted, a team of Italian astronomers led by Paolo Molaro of the Instituto Nazionale di Astrofisica at the University of Trieste used the opportunity to perform an unusual and challenging experiment, looking at the sunlight reflected off the Moon to see how it changed during the transit. This measurement, done with ESO's High Accuracy Radial Velocity Planet Searcher (HARPS) spectrograph installed on the ESO 3.6-metre telescope at La Silla in Chile, could help scientists to find planets in orbit around other stars. The team has published their results in the journal Monthly Notices of ...
