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.
It’s a combined view from four telescopes at the observatory. The article goes into a bit more detail.
I hadn’t realized there was a link; I thought it was just a picture. Thank you!
