 ESOcast 126 Light: Titanium oxide in exoplanetary atmosphere (4K UHD) | File Type: video/x-m4v | Duration: 76

Astronomers using ESO’s Very Large Telescope have detected titanium oxide in an exoplanet atmosphere for the first time. This discovery around the hot-Jupiter planet WASP-19b exploited the power of the FORS2 instrument. It provides unique information about the chemical composition and the temperature and pressure structure of the atmosphere of this unusual and very hot world.

 ESOcast 122 Light: Supermassive Black Holes Feed on Cosmic Jellyfish (4K UHD) | File Type: video/x-m4v | Duration: 95

Observations of “Jellyfish galaxies” with ESO’s Very Large Telescope have revealed a previously unknown way to fuel supermassive black holes. It seems the mechanism that produces the tentacles of gas and newborn stars that give these galaxies their nickname also makes it possible for the gas to reach the central regions of the galaxies, feeding the black hole that lurks in each of them and causing it to shine brilliantly.

 ESOcast 121 Light: Star orbiting supermassive black hole suggests Einstein is right (4K UHD) | File Type: video/x-m4v | Duration: 97

A new analysis of data from ESO’s Very Large Telescope and other telescopes suggests that the orbits of stars around the supermassive black hole at the centre of the Milky Way show the subtle effects predicted by Einstein’s general theory of relativity.

 ESOcast 120: Chile Chill 10 – “VLT Main Mirror Recoating” | File Type: video/x-m4v | Duration: 262

This video takes a relaxed look at a tense process — cleaning and recoating the surface of one of the ESO Very Large Telescope’s 8.2-metre main mirrors.

 ESOcast 119: AOF First Light | File Type: video/x-m4v | Duration: 215

ESO’s new Adaptive Optics Facility has just opened its eyes to the sky for the first time. Coupled with the revolutionary instrument MUSE, this is one of the most advanced and powerful technological systems ever built for ground-based astronomy.

 ESOcast 118 Light: A Tale of Three Stellar Cities (4K UHD) | File Type: video/x-m4v | Duration: 71

Surprise: astronomers have found what look like three different generations of baby stars​ within the Orion Nebula Cluster.

 ESOcast 117 Light: Eyes Wide Open for New Exoplanet Hunter (4K UHD) | File Type: video/x-m4v | Duration: 74

The MASCARA (Multi-site All-Sky CAmeRA) station at ESO’s La Silla Observatory in Chile has achieved first light. This new facility will seek out transiting exoplanets as they pass in front of their bright parent stars and create a catalogue of targets for future exoplanet characterisation observations.

 ESOcast 116: Success or Failure: How to Get Observing Time | File Type: video/x-m4v | Duration: 332

ESOcast 116 explores how astronomers request time to use an ESO telescope, and how ESO’s Observing Programmes Committee, embarking on its one-hundredth meeting, examines and judges these proposals in order to ensure that ESO is making the best use of its telescopes to advance our knowledge and understanding of the Universe.

 ESOcast 115 Light: Meet one of the most energetic objects in the Universe (4K UHD) | File Type: video/x-m4v | Duration: 87

ESO’s Very Large Telescope (VLT) has captured a magnificent face-on view of the barred spiral galaxy Messier 77. But there is more to this galaxy than meets the eye. This ESOcast Light takes a closer look.

 ESOcast 114 Light: VLT LEGO model (4K UHD) | File Type: video/x-m4v | Duration: 129

One of the world’s most sophisticated observatories has now been recreated as a mind-boggling LEGO® model.

 ESOcast 113 Light: Live search for Planets around Proxima Centauri continues (4K UHD) | File Type: video/x-m4v | Duration: 74

In 2016 the Pale Red Dot team discovered a planet around Proxima Centauri, the closest star to our Sun. Using ESO’s exoplanet hunter, HARPS, they are about to continue the hunt for the nearest exoplanets. See more in this episode of ESOcast Light.

 ESOcast 112: Catching Starlight | File Type: video/x-m4v | Duration: 237

Capturing and recording the light from the heavens has always been an essential aspect of astronomy. In this episode, we’re going to delve into the history of the sensors that have been used to study the Universe over the centuries.

 ESOcast 111 Light: VST captures glowing celestial triplet | File Type: video/x-m4v | Duration: 100

 ESOcast 110 Light: Ingredient for life found around infant stars (4K UHD) | File Type: video/x-m4v | Duration: 79

ALMA has observed stars like the Sun at a very early stage in their formation and found traces of methyl isocyanate — a chemical building block of life.

 ESOcast 109 Light: Full steam ahead with ELT primary mirror (4K UHD) | File Type: video/x-m4v | Duration: 113
