ESOcast 208 Light: A Cosmic Pretzel (4K UHD) 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. ESO Video Casts Go to SourceRead More →

ESOcast 207 Light: Enigmatic radio burst illuminates a galaxy’s tranquil ​halo (4K UHD) 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. ESO Video Casts Go to SourceRead More →
