4 maart 2014: Award-winning French actress Juliette Binoche and Irish actor Gabriel Byrne visited ESO’s Paranal Observatory in northern Chile on 22 February 2014. Juliette Binoche then travelled on to visit ALMA on 24 February. Famed for their performances in many successful films, Juliette Binoche and Gabriel Byrne expressed an interest in visiting the most prominent observatories during their free time in northern Chile. They are currently shooting an upcoming film named The 33 — based on the dramatic true story of the miners who were successfully rescued after many weeks trapped underground following an accident at the San José mine in 2010. The actress and actor were hosted at Paranal by ESO's Director of Administration Patrick Geeraert and ESO's Representative in Chile Fernando Comerón. Arriving in time to watch the sunset at Cerro Paranal on 22 February, they saw the opening of the VLT domes as they prepared for the night ahead. ...

19 februari 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. More Information The ESOcast is a video podcast series dedicated to bringing you the latest ...

18 februari 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 ...

13 februari 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 ...

10 februari 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 ...

4 februari 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 ...

31 januari 2014: On 27 March 2014, ESO will participate in Germany’s nationwide Girls’ Day activities. The annual event sees technical enterprises, universities and research organisations open their doors to female school students, in order to provide an insight into science and technology professions. Such open days help girls to make well-informed decisions about their future and encourage them to choose careers in science and technology. The ESO Girls’ Day, An Introduction to the Work of the European Southern Observatory, comprises a series of talks in German and question-and-answer sessions with ESO staff and students. Many aspects of astronomy and engineering (optics, mechanical engineering, construction, software engineering etc) will be covered. To conclude this introduction to the world’s most productive astronomical observatory, there will be a live video link to ESO’s Very Large Telescope (VLT). Located 2600 metres above sea level on Cerro Paranal, the VLT is the world’s most advanced optical instrument ...

27 januari 2014: ESO has launched a pioneering expedition into the Ultra High Definition Universe. This campaign will document the travels and work of four world-renowned astrophotographers and ESO Photo Ambassadors as they journey through the Chilean Atacama Desert, equipped with the powerful tools of imaging technological leaders. ESO’s videographer Herbert Zodet and the three Photo Ambassadors, Yuri Beletsky, Christoph Malin and Babak Tafreshi embark on their expedition with the goal of capturing footage at ESO’s three unique observing sites in all their grandeur — using state-of-the-art Ultra High Definition 4K still and video cameras The team will first travel up to Paranal, home to ESO’s flagship facility Very Large Telescope array (VLT), before continuing to ALMA, the Atacama Large Millimeter/submillimeter Array at 5000 metres above sea level. Their trip will finish at La Silla, ESO’s first observatory in Chile. The team will capture crisp Ultra High Definition time-lapse images, stills, videos and ...

22 januari 2014: ESO first introduced HD video as a format for its public videos in 2008 and we now have over 1600 videos in this format in our video archive. The newer Ultra HD format has now been added as one of the many video formats that are offered for parts of the video collection [1]. The Ultra HD format [2] has twice the horizontal and vertical resolution of the standard 1080p HDTV format — four times as many pixels. The format has been under development since 2003, but rose to prominence in 2013 and has since become standard on many high-end TV displays. This popular new format has also recently had a lot of media exposure, including extensive coverage at the International Consumer Electronics Show, which took place in late 2013. Ultra HD content is so far quite difficult to find, although internet streaming services such as Netflix and Amazon Instant ...

21 januari 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 ...

15 januari 2014: In this ESOcast we look at how astronomers have used ESO's HARPS planet hunter in Chile, along with other telescopes around the world, to discover three planets orbiting stars in the cluster Messier 67. Although more than one thousand planets outside the Solar System are now confirmed, only a handful have been found in star clusters. Remarkably one of these new exoplanets is orbiting a star that is a rare solar twin — a star that is almost identical to the Sun in all respects.

31 december 2013: In February 2011 we opened a Flickr Group, called “Your ESO Pictures” to encourage people to share their photos that revealed interesting aspects of ESO. Visitors to our sites often say that it is a life changing experience and we were curious to know what impresses them most. The initiative proved to be very popular, recently passing the 1000 photos milestone, for which we would like to thank all our Flickr friends! Many of the photos shared with us became Pictures of the Week on the ESO homepage, as we wanted to recognise people’s excellent work, while some of the contributors were invited to join our network of Photo Ambassadors. We invite you to discover 1000 views on ESO and contribute your own to Your ESO Pictures. As a new idea for the Flickr we also encourage pictures that show “ESO from the inside” — either from staff or visitors. ...

10 december 2013: Tijdens een ceremonie in ESO’s Vitacura-kantoot in Santiago hebben Tim de Zeeuw, directeur-generaal van ESO, en hoge vertegenwoordigers van het Chileense bedrijf ICAFAL Ingeniería y Construcción S.A. een contract getekend voor de aanleg van een weg naar de top van Cerro Armazones, het afvlakken van de top van de berg en aanvullende bouwkundige werkzaamheden. De ceremonie werd ook bijgewoond door vertegenwoordigers van het ESO-projectteam. Cerro Armazones wordt de locatie van de 39-meter European Extremely Large Telescope (E-ELT). De 3000 meter hoge bergtop ligt op twintig kilometer afstand van de ESO-sterrenwacht op Paranal, in de Atacamawoestijn van noordelijk Chili. De in het contract beschreven werkzaamheden zullen in maart 2014 beginnen en naar verwachting zestien maanden in beslag nemen. Dat is inclusief aanleg en onderhoud van een verharde weg, de aanleg van het topplatform en het graven van een facilitaire greppel naar de top. Deze werkzaamheden zijn nodig om straks de reusachtige ...

6 december 2013: The ESO Council, at its meeting this week in Garching, has approved the appointment of Roberto Tamai as Programme Manager for the European Extremely Large Telescope (E-ELT), effective 1 February 2014. Roberto replaces Alistair McPherson who has very successfully steered the E-ELT project through its early stages. Alistair is returning to the United Kingdom as Deputy Director General/Head of Project for the Square Kilometre Array (SKA), based at Jodrell Bank near Manchester. Roberto comes from Naples and was educated in Italy and at Berkeley, Calfornia. He started his career working on the ESA Hypersonic Plasma Wind Tunnel Project and subsequently has had a distinguished career at ESO, both in Chile and in Garching. In 1999 he moved to Paranal as a mechanical engineer and became the Head of the Engineering of Paranal Observatory, and then Deputy Director of the La Silla Paranal Observatory.
