On 19 June 2014, a major milestone on the road to the construction of the European Extremely Large Telescope was reached. Part of the 3000-metre peak of Cerro Armazones was blasted away as a step towards levelling the summit. This paves the way for the largest optical/infrared telescope in the world.

In the Spring of 2014, a team of ESO Photo ambassadors embarked on a pioneering expedition to ESO's three observatories in Chile. Their mission was to capture a wide range of images and timelapses of the magnificent Chilean night sky and landscape in crisp Ultra High Definition. Join our heroes in their adventures in the arid Atacama Desert as they bring our Universe closer than ever before.
The clear night sky offers one of the most beautiful views in nature. The eye adapts to the dark and the pupil widens to collect more light and thus allow fainter stars to become visible. But the light-collecting area of the human eye is tiny. To peer much deeper into the night sky astronomers need telescopes with enormous primary mirrors to do a much better job.

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.

Astronomers know that planets around other stars beyond the Solar System are common. But these planets are very hard to see and even harder to study. Fortunately, there is a clever trick that helps to separate the feeble glow of a planet from the dazzling glare of its parent star: exploiting the polarisation of the light reflected from the planet.

The detection of this “dust trap” solves a long-standing mystery: how dust particles around stars sum up to form planets, comets, and other rocky bodies. ESOcast 58 goes deep into the dust trap to explore how this comet factory works. More information and download options are available on: http://www.eso.org/public/videos/eso1325a/
May 25 2013 is an important anniversary for the Very Large Telescope – it is exactly fifteen years since the first light on the first of its four Unit Telescopes. Since then the four original giant telescopes have been joined by the four small Auxiliary Telescopes that form part of the VLT Interferometer (VLTI). The VLT is one of the most powerful and productive ground-based astronomical facilities in existence. In 2012 more than 600 refereed scientific papers based on data from the VLT and VLTI were published. This ESOcast shows spectacular images from the VLT for every year of its operation.

For our newest ESOcast, we pose this puzzle: how do you move a 100-tonne giant ALMA antenna 30 kilometres up onto the oxygen-starved Chajnantor Plateau, 5000 metres above sea level and finish the job with millimetre precision?

The ALMA inauguration ESOcast. Share the excitement of the inauguration ceremony and contemplate the breathtaking images from ALMA itself and views of its unique environment in the Atacama Desert. This event marks the completion of all the major systems of the giant telescope and the formal transition from a construction project to a fully fledged observatory. ALMA is a partnership between Europe, North America and East Asia in cooperation with the Republic of Chile. Credits and download options are available on: http://www.eso.org/public/videos/eso1312b/
On 13 March 2013 the Atacama Large Millimeter/submillimeter Array (ALMA) was inaugurated at an official ceremony in the Chilean Andes, marking the completion of all the major systems of the giant telescope and the formal transition from a construction project to a fully fledged observatory. This 16-minute video presents the history of ALMA from the origins of the project several decades ago to the recent first science results. Illustrated by dramatic helicopter footage, the movie takes you on a journey to the 5000-metre-high Chajnantor Plateau, where ALMA stands, in the unique environment of the Atacama Desert of Chile.

One of the most powerful supercomputers in the world has now been fully installed and tested at its remote, high altitude site in the Andes of northern Chile. This marks one of the major remaining milestones toward completion of the Atacama Large Millimeter/submillimeter Array (ALMA), the most elaborate ground-based telescope in history. The special-purpose ALMA correlator has over 134 million processors and performs up to 17 quadrillion operations per second, a speed comparable to the fastest general-purpose supercomputer in operation today.

This episode of the ESOcast introduces a new type of ESOcasts called "Chile Chill". These ESOcasts offer a calm experience of the Chilean night sky and ESO's observatory sites, undisturbed by facts or narration. In this episode we follow a typical night of observing for ESO's telescopes. Credit: ESO
This exciting episode of the ESOcast gives viewers an exclusive backstage pass to see what went on behind the scenes while filming the ESO live webcast “A Day in the Life of ESO”. The webcast aired on the exact date of ESO’s 50th Anniversary, 5th October 2012, and lasted for 6 hours. It included talks from astronomers and engineers from ESO’s headquarters in Garching, Germany, as well as a live link to Paranal, Chile, where Brigitte Bailleul, winner of the “Tweet your way to the VLT” competition, was preparing to be the first member of the general public to make an observation using ESO’s Very Large Telescope (VLT). ESOcast 49 examines the events of the day and also includes footage taken behind the scenes both at Garching as well as Paranal.
Leading up to ESO’s 50th anniversary in October 2012, we are releasing eight special ESOcasts, each a chapter from the movie Europe to the Stars — ESO’s First 50 Years of Exploring the Southern Sky. ESOcast 48 — entitled Building Big — is the eighth and final special episode of this series. It relates how ESO - based on its experience over the past fifty years as the most powerful observatory in History - is going to realise the everlasting longing of astronomers: the construction of even bigger telescopes.

Leading up to ESO’s 50th anniversary in October 2012, we are releasing eight special ESOcasts, each a chapter from the movie Europe to the Stars — ESO’s First 50 Years of Exploring the Southern Sky. ESOcast 47 — entitled Reaching Out — is the seventh special episode of this series. In this episode we look at one of the major longings that astronomers have pursued over centuries: finding life in the Universe. ESO has played an important role in this exciting journey.
