Summary

Description	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. This short ESOcast takes a quick look at this remarkable result. The video is available in 4K UHD. The ESOcast Light is a series of short videos bringing you the wonders of the Universe in bite-sized pieces. The ESOcast Light episodes will not be replacing the standard, longer ESOcasts, but complement them with current astronomy news and images in ESO press releases. Credit : ESO.
