17 July 2015: After more than five years of development and construction, ALMA successfully opened its eyes on another frequency range after obtaining the first fringes with a Band 5 receiver, specifically designed to detect water in the local Universe. Band 5 will also open up the possibility of studying complex molecules in star-forming regions and protoplanetary discs, and detecting molecules and atoms in galaxies in the early Universe, looking back about 13 billion years. ALMA observes the Universe in radio waves: light that is invisible to the human eye. The weak electromagnetic glow from space is captured by the array of 66 antennas, each with diameters up to twelve metres. Their receivers transform this weak radiation into an electrical signal. To scout a broad range of frequencies, each ALMA antenna is equipped with up to ten different receivers, each one specially designed to cover a specific range of wavelengths. The new Band ...

16 July 2015: On 15 and 16 July 2015, the Cherenkov Telescope Array (CTA) Resource Board decided to enter into detailed contract negotiations for hosting the CTA’s southern hemisphere array within the grounds of the Paranal Observatory, one of ESO’s sites in Chile. Similar negotiations for a northern site on La Palma are also starting. The CTA project is an initiative to build the next generation of ground-based instruments designed for the detection of very high energy gamma-rays. Gamma rays are emitted by the hottest and most powerful objects in the Universe — such as supermassive black holes, supernovae and possibly remnants of the Big Bang. The array will provide valuable deeper insights into the high-energy Universe. Although gamma rays don’t make it to the Earth’s surface, the CTA’s mirrors and high-speed cameras will capture short-lived flashes of the characteristic eerie blue Cherenkov radiation that is produced when the gamma rays interact with ...

The journal addresses science teaching ...

10 July 2015: Following the recommendations of the ESO Finance Committee (FC) and Scientific Technical Committee (STC), Council authorised the Director General to sign the contracts for the first set of instruments for the E-ELT. These huge and innovative tools to analyse the light collected by the giant telescope will allow the E-ELT to address a wide range of astronomical questions soon after its completion. The choices are based on extensive input from the astronomical communities in ESO’s Member States. This instrumentation package comprises a near-infrared imager with spectroscopic capability (MICADO), a multi-conjugate adaptive optics unit (MAORY), which will feed MICADO (and possibly additional future instruments); an integral field spectrograph (HARMONI), along with development of its laser tomography adaptive optics system to preliminary design review level; and a mid-infrared imager and spectrometer (METIS). MICADO, coupled with MAORY, will allow the full resolution of the telescope to be brought to bear on many current ...

8 July 2015: ESO has signed a contract with the French optics company Reosc, a subsidiary of Sagem, Safran group, to manufacture the deformable shell mirrors that will comprise the fourth mirror (M4) of the European Extremely Large Telescope (E-ELT) These mirrors will be mounted and supported in the adaptive mirror unit (ann15045) to form the largest ever adaptive mirror unit ever made. The contract was signed by representatives of Reosc and ESO at a ceremony at ESO Headquarters on 8 July 2015. The M4 deformable mirror system forms a key part of the E-ELT.

26 June 2015: The ALMA Observatory recently received its first art exhibit: a golf ball of enormous proportions, displayed alongside the antennas at an altitude of 5000 metres above sea level on the Chajnantor Plateau. This inflatable work of art is part of a travelling project named Mixed Game (Juego Mixto) by Dagmara Wyskiel [1], a Polish artist who has lived in Antofagasta, northern Chile, for over a decade. After the giant ball completes its journey through the Atacama Desert, it will roll on to Grey Glacier in Magallanes and then to the shores of Valparaiso. “Mixed Game involves the introduction of an enigmatic but at the same time visually synthetic object into diverse open spaces of the landscape,” explains the artist, who is responsible for a production related to contemporary art, graphic design, art education and cultural development. Dagmara Wyskiel adds that “the object introduced suggests that something may have finally appeared ...

25 June 2015: The Inamori Foundation has announced Michel Mayor as one of the laureates of the 2015 Kyoto Prize. The other laureates are chemist Toyoki Kunitake and choreographer John Neumeier. Michel Mayor, who is Professor Emeritus at Geneva University in Switzerland and has spent sabbatical semesters with ESO in Chile, was honoured for “answering a fundamental age-old question of astronomy regarding the existence of exoplanets by discovering 51 Pegasi b, the first one orbiting a Sun-like star… and opening an entirely new field of research.” The lasting impact of his discovery is illustrated in recent observations of 51 Pegasi b made using ESO’s HARPS instrument. Michel Mayor was the leader of the group that developed and exploited the power of HARPS, the world’s leading planet-hunting machine. The Kyoto Prize Presentation Ceremony will be held in Kyoto, Japan, on 10 November 2015. Each laureate will receive a diploma, the Kyoto Prize medal and ...

15 June 2015: The first prototype of a new generation of fast and very sensitive detectors has been successfully installed on the PIONIER instrument at ESO’s Paranal Observatory. This achievement is the result of five years of sustained collaboration and effort from academic institutes (LETI, ONERA, IPAG, LAM) and industrial partners (SOFRADIR). As its name suggests, the new RAPID system [1] delivers several thousand images per second and can operate at very low light levels. These capabilities, unique for an infrared detector, are crucial for many applications, ranging from fundamental science to medicine. In astronomy, it will boost the performance of adaptive optics, a technology at the heart of the European Extremely Large Telescope (E-ELT). Unlike most of the commercially available detectors, RAPID can spot photons (light particles) of both visible and infrared light (wavelengths from 0.4–3.6 micrometres). This is a tremendous gain; the increased spectral coverage means that far more photons can ...

9 June 2015: ESO has signed an agreement to license its cooling system technology to the Spanish company FRACTAL SLNE. This follows earlier technology transfer agreements regarding the licensing of cutting-edge laser technology that were made by ESO in 2010 [1]. Such licences offer significant opportunities both for industry and for ESO. Continuous flow cooling systems were first developed at ESO for the cooling of instruments and detectors for the Very Large Telescope (VLT). The technology has been used intensively during the last decade. Continuous flow systems are more compact than traditional systems that use a bath of very cold liquid, but share the advantage of being vibration free [2]. The continuous flow system allows the temperature within an instrument to be changed from room temperature to –193 degrees Celsius and is not affected by the loss of electrical power. As a result, the instrument can be kept very close to its operating ...
