ESOcast 64: First Ring System Around an Asteroid
26 March 2014: This episode of the ESOcast presents the recent discovery that the remote asteroid Chariklo is surrounded by two dense and narrow rings. Telescopes at seven locations in South America, including the 1.54-metre Danish and TRAPPIST telescopes at ESO’s La Silla Observatory in Chile were used to make this surprise discovery in the outer Solar System. This unique finding has sparked much interest and debate since it is the smallest object by far to have rings and only the fifth body in the Solar System — after the much larger planets Jupiter, Saturn, Uranus and Neptune — to have this feature. Astronomers think that this sort of ring is likely to be formed from debris left over after a collision. The story of this unique and unexpected discovery is told in ESOcast 64: First Ring System Around an Asteroid. More episodes of the ESOcast are also available. Find out how to ...

Powerful New Laser Passes Key Test
24 March 2014: A new 22-watt laser has now been accepted from the system supplier TOPTICA and its partner MPB following nearly five years of sustained collaboration and effort (see ann1045, ann1048, ann11039, ann12012 and ESOcast 34). This laser system will form part of the Adaptive Optics Facility at ESO’s Very Large Telescope (VLT) [1]. This laser, and four further similar units (including one spare) that will be delivered later, constitute key elements of the new facility and this acceptance marks a major step forward for the project. Five years ago the options for obtaining high power, reliable lasers in a compact format suitable for the requirements of the Adaptive Optics Facility were very limited. But now new technology and dedicated research and development have changed the landscape. After three months of acceptance testing at ESO, the project team was very happy with the performance of the new hardware, which holds great promise for simple ...

Road to Armazones Started
14 March 2014: The civil works for the European Extremely Large Telescope (E-ELT) have begun. The Chilean company, ICAFAL Ingeniería y Construcción S.A. (ICAFAL), has started construction of a road to the summit of Cerro Armazones. Currently there is no paved road from the public highway to the top of the mountain. The road construction work is expected to take 16 months and will provide access to the summit for the future construction work on the giant telescope. Once complete, the road will be 11 metres wide in total, with an asphalt paved driveway of 7 metres width.  ICAFAL will also be responsible for the levelling of the top of the mountain later this year and additional civil works. The peak must be modified to create a platform to construct the telescope and other supporting facilities. The start of telescope operations is planned for early in the next decade, when the E-ELT will ...

ESO Remains World’s Most Productive Ground-based Observatory
14 March 2014: A survey of the number of peer-reviewed scientific papers published in 2013 using data from ESO’s telescopes and instruments has shown that ESO remains the world’s most productive ground-based observatory. Astronomers used observational data from ESO facilities to produce 840 refereed papers last year. The number of papers published from ESO data in 2013 has even remained slightly higher than the number of papers using data from the NASA/ESA Hubble Space Telescope. Nearly 70% of all papers credited to ESO in 2013 used data acquired using the Very Large Telescope (VLT) or VLT Interferometer facilities. The most productive VLT instruments in terms of papers remain FORS2 and UVES. X-shooter also showed a steep increase in the number of publications and has produced a total of almost 170 papers from 2010 to 2013. Other facilities at the La Silla Paranal Observatory — including the survey telescope VISTA at Paranal, as well ...

ESOcast 63: Flexible Giants — The Evolution of Telescope Mirrors
19 February 2014: In our latest episode of the ESOcast, we delve into the history of telescope mirrors and their evolution over time. Enormous telescope mirrors allow astronomers to peer much deeper into the night sky than the tiny light-collecting area of the human eye permits. In this episode, the reason for the ever-growing size of telescopes is explored as the story behind these flexible giants is told. The challenges of building larger yet lighter mirrors have paved the way for innovative thinking and have consequently led to telescope designs such as ESO’s New Technology Telescope (NTT) and the future European Extremely Large Telescope (E-ELT). To find out how and why such designs revolutionised telescope mirror design, explore the past, present and future of telescope mirror design in ESOcast 63: Flexible Giants — The Evolution of Telescope Mirrors.

Exoplanet Imager SPHERE Shipped to Chile
18 February 2014: SPHERE — the Spectro-Polarimetric High-contrast Exoplanet REsearch instrument — is a powerful new facility for finding and studying exoplanets. The instrument has recently successfully completed testing in France, passed preliminary acceptance by ESO, and has now been shipped to Chile. It will then be installed on ESO’s Very Large Telescope (VLT) and first light is foreseen for May 2014. SPHERE was built by a consortium of astronomers and engineers in many ESO states in conjunction with industry [1]. The consortium is led by the Institut de Planétologie et d'Astrophysique de Grenoble, France. SPHERE’s main goal is to find and characterise giant exoplanets orbiting nearby stars by direct imaging [2]. This is an extremely challenging task as such planets are both very close to their parent stars in the sky and also very much fainter. In a normal image, even in the best conditions, the light from the star totally swamps ...

Austrian Superfast Adaptive Optics Algorithms for the E-ELT
13 February 2014: As part of the Austrian contribution when it joined ESO, a specialist team from institutes in Linz [1] has developed adaptive optics algorithms and software methods that are much faster than those using more traditional approaches. These methods are used for the correction of images that are degraded due to atmospheric turbulence — and are in particular intended for use with the future 39-metre European Extremely Large Telescope (E-ELT). The challenging goal was to invent a new and different approach to this problem that is as effective as current techniques while, at the same time, greatly reducing the computing load on the computer that performs the calculations. This four-year project has just completed a very successful final review. The new adaptive optics algorithms are very fast and provide excellent quality results. This leads to enormous savings in computing power required to handle adaptive optics data from the E-ELT. But probably ...

3D Printing of VLT Components
10 February 2014: ESO has recently utilised the innovative technology of 3D printing [1] to manufacture moulds for the casting of two new telescope components. These are required for the MUSE instrument on ESO's Very Large Telescope (VLT) in Chile and are part of the Adaptive Optics Facility project. The 3D printing technique offers great promise in the manufacture of complex custom items, which are often needed in astronomical instrumentation, delivering the components more quickly and cheaply, and with greater flexibility. The first item, which was manufactured by the German firm voxeljet AG, is the structural part of a new sensor arm [2] that was installed in the telescope to work with the MUSE instrument. This change was also needed to accommodate the GALACSI adaptive optics module to be installed in 2015. The sensor arm is a metallic structure that is used to hold three flat mirrors [3], which feed light beams into ...

Improved Adaptive Optics Mirror Delivered
4 February 2014: In December 2011, the French company Safran–Reosc delivered their first thin shell Zerodur mirror to ESO (ann12015). The company has now topped this by delivering a second shell mirror [1] of even higher quality than the first. Both mirrors are a mere 2 millimetres thin but 1.12 metres in diameter, and will be crucial for the upgrade of Unit Telescope 4 of ESO’s Very Large Telescope (VLT) to a fully adaptive system [2]. A thin shell mirror is deformed several thousand times per second to compensate for turbulence in the Earth’s atmosphere. The result is a much sharper image, allowing astronomers to study the Universe in greater detail than possible before. The new shell features many improvements. It has a surface accuracy that is better by a factor of five than the older one and very small forces are needed to correct the shape of the mirror’s surface, half that ...

ESA/ESO Collaboration Successfully Tracks Its First Potentially Threatening Near-Earth Object
21 January 2014: The first Near-Earth Object (NEO) recovery campaign has been successfully carried out by a new collaboration between the European Space Agency (ESA) and ESO. Up to now the asteroid 2009 FD had been ranked among the top five objects in a list of the most dangerous objects, but new observations with ESO's Very Large Telescope (VLT) have now shown that it is far less likely to hit the Earth than had been feared [1]. NEOs are asteroids or comets with orbits around the Sun that come very close to the Earth's orbit. More than 600 000 asteroids are known in the Solar System, and more than 10 000 of them are NEOs. Their sizes range from metres to tens of kilometres. Some NEOs could hit our planet and, depending on their size, produce considerable damage. While the chance of a large object hitting the Earth is very small, it could ...
