How will the sun of the solar system die?

The European Aerospace Agency (ESA) has just released an image of a dying star, reflecting what will happen to our Sun in the next 5 billion years.

The dying star Kohoutek 4-55 , which was named after the Czech astronomer who discovered it - Luboš Kohoutec. This star is located at 4,600 light-years from Earth, in the direction of the constellation Cygnus and possesses a mass close to the Sun.

The dying 4-55 Kohoutek is the last "beautiful picture" captured by the Hubble Space Telescope's WFPC2 lens before "retiring" after 16 years of continuous operation. WFPC2 has taken a lot of iconic photos, making the name Hubble famous worldwide.

Kohoutek 4-55's photo of the dying scene is actually a product of three separate photos, with each shot taken at a certain wavelength to isolate the light coming from different gas atoms. Different wavelengths are color coded to support identification. In it, red indicates nitrogen, green represents hydrogen and blue represents oxygen.

Describing the image, ESA said: " Complex spiral vortices reveal the distant future of our Sun. In another 5 billion years, our star will be in a dying state. It is expected to behave exactly as we see it in this photo: peeling the outer layers to reveal the burning core, then becoming a "embers" that are cooling off, called white dwarf.

At that time, the Earth had even "died" long before and burned down when the Sun was over. However, the scene of the dying Sun will shine throughout the universe. "

Experts further explained that, when a star gets older, nuclear reactions make it brighter, starting to decline. The production of this slowing energy causes the stars to fluctuate abnormally, dumping the outer layers into space. And when this exhaust is removed, the superheated core will expose.

At this point, the rest of the star will emit a large amount of ultraviolet light. This radiation causes the shell structure to shine brightly, creating the fragile beauty of the nebula.
