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

On 11 October 2014 the ESO Headquarters in Garching, Germany, once more opened their doors to the public. Some 3 300 people used this special opportunity of the Open House Day to visit the centre of the world's foremost astronomical organisation.
This new ESOcast features six specialists in different areas who work at ESO in Germany and in Chile. Get to know the work they do at ESO, but also learn about interesting hobbies they pursue in their free time and how these hobbies may be connected to their work.

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.
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.

This ESOcast is about the discovery of the most distant quasar found to date. This brilliant beacon is powered by a black hole with a mass two billion times that of the Sun. It is by far the brightest object yet discovered in the early Universe. More information: http://www.eso.org/public/videos/eso1122a/
ESO has just released a stunning new image of a field of stars towards the constellation of Carina. This striking view is ablaze with a flurry of stars of all colours and brightnesses, some of which glow against a backdrop of gas and dust clouds. A complex nebula created by previous, violent ejections surrounds an unusual star in the middle of this field. Astronomers have discovered that this star has a companion. Interactions in this double star system, surrounded by a dusty disc, may be the engine fuelling the star’s remarkable nebula. More info and credits at http://www.eso.org/public/videos/eso0928b/
This joint episode of the Hubblecast and ESOcast presents Abell 2744, an unusual cluster of galaxies nicknamed "Pandora's Cluster" by the astronomers who have studied it. Looking at the galaxies, gas and dark matter in the cluster, scientists have reconstructed the series of huge collisions that created it, and have uncovered some strange phenomena never seen together before.

This ESOcast takes a close look at an unusual new group of small telescopes that has recently achieved first light at ESO’s Paranal Observatory in northern Chile. More information, full credits and download options are available on: http://www.eso.org/public/videos/eso1502a/
A European team of astronomers using ESO’s Very Large Telescope (VLT) has measured the distance to the most remote galaxy so far. By carefully analysing the very faint glow of the galaxy they have found that they are seeing it when the Universe was only about 600 million years old (a redshift of 8.6). These are the first confirmed observations of a galaxy whose light is clearing the opaque hydrogen fog that filled the cosmos at this early time.

Astronomers using ESO instruments have discovered a remarkable extrasolar planetary system that has some striking similarities to our own Solar System. At least five planets are orbiting the Sun-like star HD 10180, and the regular pattern of their orbits is similar to that observed for our neighbouring planets. One of the new extrasolar worlds could be only 1.4 times the mass of the Earth, making it the least massive exoplanet ever found. This video podcast explains how these faraway planets were detected and exactly what we know about them. Credits and more information at: http://www.eso.org/public/videos/eso1035a/
The European Extremely Large Telescope — or E-ELT for short — will be by far the largest optical and near-infrared telescope in the world. In early December 2014 the ESO Council gave the go-ahead for the first construction phase of the telescope.

Astronomers using ESO’s leading exoplanet hunter HARPS have today announced more than fifty newly discovered planets around other stars. Among these are many rocky planets not much heavier than the Earth. One of them in particular seems to orbit in the habitable zone around its star. This ESOcast we look at how astronomers discover these distant worlds and what the future may hold for finding rocky worlds like the Earth that may support life.

An exoplanet orbiting a star that entered our galaxy, the Milky Way, from another galaxy has been detected by a European team of astronomers using the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in Chile. The Jupiter-like planet is particularly unusual, as it is orbiting a star nearing the end of its life and could be about to be engulfed by it, giving clues about the fate of our own planetary system in the distant future.

ESOcast 69 presents the result of the latest ALMA observations, which reveal extraordinarily fine detail that has never been seen before in the planet-forming disc around the young star HL Tauri. This revolutionary image is the result of the first observations that have used ALMA with its antennas at close to the widest configuration possible. As a result, it is the sharpest picture ever made at submillimetre wavelengths. More information, full credits and download options are available on: http://www.eso.org/public/videos/eso1436a/
The Orion Nebula reveals many of its hidden secrets in a dramatic image taken by ESO’s new VISTA survey telescope. VISTA — the Visible and Infrared Survey Telescope for Astronomy — is the latest addition to ESO’s Paranal Observatory. It is the largest survey telescope in the world and is dedicated to mapping the sky at infrared wavelengths. The telescope’s huge field of view can show the full splendour of the Orion Nebula and VISTA’s infrared vision also allows it to peer deeply into dusty regions that are normally hidden and expose the curious behaviour of the very active young stars buried there.

In principle, the larger a telescope’s mirror, the finer the details it can see. Continuing to increase the size of telescope mirrors is not an easy task, so astronomers have come up with a new technology to see even finer details: interferometry. This observational technique combines the light received by two or more telescopes and allows them to act as a single unit with a mirror diameter equivalent to the distance between the telescopes.
