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.
Astronomers have captured the earliest minutes of two exploding stars and for the first time seen a shockwave generated by a star’s collapsing core. The international team found a shockwave only in the smaller supernova — a finding that will help them understand these complex explosions that create many of the elements that make up the Earth and solar system.
