ESOcast 123 Light: Best Ever Image of a Star’s Surface and Atmosphere (4K UHD) Using ESO’s Very Large Telescope Interferometer astronomers have constructed the most detailed image ever of a star — the red supergiant star Antares. They have also made the first map of the velocities of material the atmosphere of a star other than the Sun, revealing unexpected turbulence in Antares’s huge extended atmosphere.

ESOcast 122 Light: Supermassive Black Holes Feed on Cosmic Jellyfish (4K UHD) 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 117 Light: Eyes Wide Open for New Exoplanet Hunter (4K UHD) 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.
