Best Ever Image of a Star’s Surface and Atmosphere - First map of motion of material on a star other than the Sun

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 in the atmosphere of a star other than the Sun, revealing unexpected turbulence in Antares’s huge extended atmosphere. The results were published in the journal Nature.

So far, the best ever image of a star other than our sun.
