For example, W Hydra scientists were able to predict the future of the Sun.
Astronomers managed for the first time in detail to study the surface of the red giant W Hydra, which was almost double the Sun, and is now in the final stages of evolution. On their observations, the researchers reported in the journal Nature Astronomy.
The star is at a distance of 254 light-years from Earth. She is much older than the Sun, and proèvolûcionirovalo to the stage of red giant, swollen and if we continue the analogy with the Sun – swallowed space until the orbits of Earth and Mars. In the diagram of Hertzsprung – Russell it is in the region of the asymptotic branch, which ever will be the Sun among the large, bright and cool stars, continues to rapidly lose ground.
W Hydra was the first in its class, which failed to consider in such detail, noting some unexpected for scientists details; so, she discovered a compact and bright spot. The stain may indicate either an unusually bright flare in the chromosphere of the star, accidentally coinciding with the time of observation, or of the action of shock waves, heating the area to extremely high temperatures.
