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.
Astronomers have used the ESO’s Very Large Telescope in Chile to image 42 of the biggest main-belt asteroids. Meet some of the 42 in this video summarising the discovery!
