After The Star Dies
After the planetary nebula fades, remaining the rest of the star burns its remaining fuel for about a billion years. Then this will become uvezda tiny — but very hot and heavy — a white dwarf, which will then laganohladini over the next few billion years. Sun will also create a planetary nebula billions of years in the future and spend their remaining years as a white dwarf.
Planetary nebulae play a crucial role in the chemical enrichment and evolution of the universe. Chemical elements such as carbon and nitrogen, as well as some heavier elements are produced in stars and interstellar matter in return. From this material are born new stars, planets and possibly form and life. From here stems famous statement astronomer Carl Sagan: “We are all made of the stellar material.”
This picture belongs to the ESO Cosmic Gems program, an initiative with the aim of producing images of interesting, intriguing and visually attractive objects using ESO telescopes to educate and inform the public. The program uses telescopes at the time can not be used with scientific research. All data collected can be eligible for use for scientific purposes and are available to astronomers through ESO’s science archive.
