ESOcast 213 Light: Stunning stars in the Milky Way central region | File Type: video/x-m4v | Duration: 84

ESO's Very Large Telescope (VLT) has observed the central part of the Milky Way with spectacular resolution and uncovered new details about the history of star birth in our galaxy. Watch this video summary to find out more about the stunning image captured with the HAWK-I instrument on the VLT and the discoveries made about star formation in the central region of our Galaxy.

ESOcast 212 Light: First Giant Planet around White Dwarf Found | File Type: video/x-m4v | Duration: 81

Researchers using ESO's Very Large Telescope have, for the first time, found evidence of a giant planet associated with a white dwarf star. The planet orbits the hot white dwarf, the remnant of a Sun-like star, at close range, causing its atmosphere to be stripped away and form a disc of gas around the star.

ESOcast 211 Light: ESO Telescope Reveals What Could be the Smallest Dwarf Planet in the Solar System | File Type: video/x-m4v | Duration: 79

Astronomers using the SPHERE instrument on ESO's Very Large Telescope have revealed that the asteroid Hygiea could be a dwarf planet. Find out more about this fascinating object in the new ESOcast Light.

ESOcast 210 Light: First identification of a heavy element born from neutron star collision | File Type: video/x-m4v | Duration: 85

Newly created strontium, an element used in fireworks, has been detected in space for the first time following observations with ESO’s Very Large Telescope. The detection confirms that the heavier elements in the Universe can form in neutron star mergers, providing a missing piece of the puzzle of chemical element formation.

ESOcast 209: Outreach and Science During the Total Solar Eclipse at La Silla | File Type: video/x-m4v | Duration: 403

On 2 July 2019, a total solar eclipse occurred over ESO’s La Silla Observatory in the Chilean Atacama Desert. ESO invited nearly 25 scientists, communicators and educators to observe and document this rare occasion from La Silla.

ESOcast 208 Light: A Cosmic Pretzel (4K UHD) | File Type: video/x-m4v | Duration: 82

The Atacama Large Millimeter/submillimeter Array (ALMA) captured an unprecedented image of two circumstellar disks, in which baby stars are growing, feeding with material from their surrounding birth disk. These observations shed new light on the earliest phases of the lives of stars and help astronomers determine the conditions in which binary stars are born.

ESOcast 207 Light: Enigmatic radio burst illuminates a galaxy’s tranquil halo (4K UHD) | File Type: video/x-m4v | Duration: 82

In November 2018 the Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope pinpointed a fast radio burst, named FRB 181112. Follow-up observations with ESO’s Very Large Telescope (VLT) and other telescopes revealed that the radio pulses have passed through the halo of a massive galaxy on their way toward Earth. This finding allowed astronomers to analyse the radio signal for clues about the nature of the halo gas.
