NASA released an image this week, showing dying star in NGC 6565 nebula located in the constellation Sagittarius. Which is 14 thousand light years away. Star is slowly radiating light outwards as it dies off. This final stage of the star is known as planetary nebula.
According to NASA and the European Space Agency (ESA), the ejection of the gas cloud left the star’s luminous core exposed to ultraviolet radiation. The interaction of this radiation with the surrounding gas releases the lights outwards, as captured by the Hubble, leading to the star’s inevitable death.

After thousands of years, the star’s center will cool down and it will shrink to become a white dwarf. A stellar remnant composed mostly of electron-degenerate matter. A white dwarf is very dense: its mass is comparable to that of the Sun, and its faint luminosity comes from the emission of stored thermal energy.
