ESOcast 123 Light: Best Ever Image of a Star’s Surface and Atmosphere (4K UHD)
Channel: European Southern Observatory (ESO)
Date: 2017-08-23

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.
