Café & Kosmos 11 October 2011
6 October 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, ...

ESOcast 34: How To Stop a Star's Twinkle
5 September 2011: We have all looked up at the sky at night and seen the stars twinkle. It may be pretty and romantic, but it is also a big problem for astronomers, as the shimmering starlight blurs observations. In this ESOcast we visit the Allgäu public observatory amid the picturesque landscape of southern Germany. Here, as night falls, a team of scientists and engineers prepares to field test a laser guide star unit, which will soon be on its way to ESO’s Paranal Observatory.

Cryogenic “Catering Truck” Comes to ALMA
2 September 2011: The ultimate in high altitude, high-tech catering has arrived in Chile to serve chilled "provisions" to the antennas at the largest astronomical complex in the world, the Atacama Large Millimeter/submillimeter Array (ALMA).Although it may look just like an airline catering truck, this vehicle is designed to carry something considerably more delicate than airplane meals! Each of the giant ALMA antennas contains a set of state-of-the-art, extremely sensitive superconducting receivers, or detectors, which are cryogenically cooled to –269 degrees Celsius (4 degrees above absolute zero). Until now, servicing these detectors has required moving the entire antenna, which weighs about 100 tonnes, from its observing site on the 5000-metre Chajnantor plateau down to the support facility at 2900 metres.The newly arrived servicing truck, called the Front End Service Vehicle (FESV), is a custom designed truck packed with the equipment required to transport these delicate detector systems without having to move the entire ...

ESO Introduces the Cosmic Gems Programme
24 August 2011: ESO is announcing a new initiative to produce spectacular astronomical images using small amounts of time on the organisation’s telescopes for the purposes of education and public outreach. This will allow ESO to continue to supply the public with spectacular colour pictures, and maintain its world-leading position in astronomy education and outreach. The first image to come out of this initiative shows a peculiar pair of galaxies — and is a stunning testament to the optical quality of the VLT and the skies over the Paranal Observatory. In this initiative, ESO’s Director General has granted dedicated observing time for outreach purposes as part of the ESO Director’s Discretionary Time programme. The small amount of time provided is mostly “low-grade time” — when the clouds roll in or there are moonlit skies not requested for science observations, and the telescopes might otherwise be idle. The data collected are also made available ...
