An international team of astronomers from Chile and Germany has managed to capture an image of unprecedented detail of another star — that isn’t the Sun — the red supergiant star Antares. The team has also made the first map of the velocities of material in the atmosphere of a star other than the Sun, revealing unexpected turbulence in the extended atmosphere of Antares. Antares, also designated Alpha Scorpii, is a well-studied, close red supergiant star at a distance of 554 light years. It is the fifteenth-brightest star in the night sky and the brightest star in the constellation of Scorpius. With a diameter about 700 times that of the Sun and a mass about 12 times solar, Antares is one of largest stars.
