A group of astrophysicists at the European southern Observatory and the Northern Catholic University of Chile presented a detailed picture of the surface and atmosphere of the star Antares. This is the most clear of currently existing pictures of stars outside the Solar system, experts say.

Using the data obtained by the interferometer, called the Very large telescope (Very Lagre Telescope, VLT) and the AMBER instrument operating in the near infrared range, the experts not only got a first detailed the stars, but was able to build a map of the movement speed of the substance in the atmosphere. Previously, the only star, which scientists had known such details was the Sun. However, the term used by researchers is the method you plan to use in order to make similar charts of other stars.
In the atmosphere of Antares scientists have discovered a turbulent gas of low density. Reportedly, he was at a much greater distance from the center of the light than shown by the theoretical calculations.
The red supergiant Antares is the brightest star in the constellation Scorpius and one of the brightest stars in the night sky. It is located at a distance of about 604 light-years from Earth. The mass of this star is “only” 12-13 times greater than the Sun, with a radius of more than a billion kilometers indicates a low density. Antares has a hot blue star and a companion called “Antares B” at a distance of about 2.9 arc seconds.
Very Large Telescope mounted on mount Cerro Paranal in Chile, the largest on Earth by the total area of mirrors of an optical telescope. He also has the highest resolution in the world. The VLT consists of four separate “main” telescopes with a diameter of 8.2 meters and four auxiliary 1.8 meters in diameter. Recently, scholars have modeled the galaxy, Medusa, absorbed by a supermassive black hole
