The red giant, to learn the fate of our Sun


In space, astronomers found a red giant, around which formed a three-dimensional spiral out of gas. R Sculptors dying star is 1.5 thousand light-years from Earth. Red giant looked through the telescope ALMA in Chile.

Red giants are the latest stage in the evolution of stars. At this stage the star expand and add to its mass, then the mass of stars scattered into space by stellar winds, spreading the substance of the universe, which is necessary for the formation of new stars. After 10-50 thousand years in the red giant burns helium, which is why there is a powerful release of gas that lasts for hundreds of years?
