 ESOcast 65: The Chilean Sky in Ultra High Definition | File Type: video/x-m4v | Duration: 705

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 time-lapses 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.

 ESOcast 64: First Ring System Around Asteroid | File Type: video/x-m4v | Duration: 293

This ESOcast shows how observations at many sites in South America, including ESO's La Silla Observatory, have made the surprise discovery that the remote asteroid Chariklo is surrounded by two dense and narrow rings.

 ESOcast 63: Flexible Giants — The Evolution of Telescope Mirrors | File Type: video/x-m4v | Duration: 463

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.

 ESOcast 62: Three planets found in star cluster | File Type: video/x-m4v | Duration: 299

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.

 ESOcast 61: Chile Chill 5 - Impressions from La Silla | File Type: video/x-m4v | Duration: 447

In this episode of Chile Chill we take a closer look at the telescopes and instruments of ESO's first observatory at La Silla in northern Chile.

 ESOcast 60: A Polarised View of Exoplanets | File Type: video/x-m4v | Duration: 457

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.

 ESOcast 59: Chile Chill 4 - Images taken by the MPG/ESO 2.2-metre telescope | File Type: video/x-m4v | Duration: 475

This ESOcast explores the wealth of stunning astronomical images produced over a period of almost 30 years by the MPG/ESO 2.2-metre telescope at the La Silla Observatory in Chile.

 ESOcast 58: ALMA Discovers Comet Factory | File Type: video/x-m4v | Duration: 366

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.

 ESOcast 57: ESO´s VLT Celebrates 15 Years of Success | File Type: video/x-m4v | Duration: 288

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.

 ESOcast 56: Gentle Giants in the Desert | File Type: video/x-m4v | Duration: 436

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 movie ALMA — In Search of our Cosmic Origins (29a) | File Type: video/x-m4v | Duration: 993

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.

 ESOcast 55: The ALMA Inauguration | File Type: video/x-m4v | Duration: 376

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.

 ESOcast 53: Chile Chill 3 | File Type: video/x-m4v | Duration: 381

This is the third installment of Chile Chill, a type of ESOcast designed to offer a calm experience of the Chilean night sky and ESO’s observing sites, undisturbed by facts or narration. In this episode we are treated to stunning views of the Atacama Desert, including the conical volcano Licancabur and slow moonrises over the Andes.

 ESOcast 52/Chile Chill 2: It's Raining Stars — a video podcast by Gianluca Lombardi celebrating the Geminid meteor shower | File Type: video/x-m4v | Duration: 241

A video podcast by Gianluca Lombardi celebrating the Geminid meteor shower.

 ESOcast 51: All Systems Go for Highest Altitude Supercomputer | File Type: video/x-m4v | Duration: 370

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.
