The process of turning the body of the Sun into a glowing nebula

When the Sun dies, its core heats up fast enough to create observable planetary nebulae from a distance of two million light years.

When dying, the Sun will turn into planetary nebula.

When the Sun reaches the end of its life cycle, it becomes a giant red star and is so wide that it can swallow some planets like Mercury and Venus. After that, it will become white dwarf and eventually die.

Newly published research on Astronomy Nature magazine points out, the Sun will turn into planetary nebulae.

Planetary nebulae form when the core of a star collapses, causing gas and dust to shoot around in the final glowing death phase. This process can last about 10,000 years.

Previous research identified the Sun's dead core as not warming fast enough for the process to occur. But the new study proves that it can heat up three times faster than previously speculated. That means it can create a planetary nebula.

One member of the research team said the nebula can be seen from the Andromera galaxy 2 million light-years away.
