A planetary nebula is an expanding cloud of gas ejected from a star that is nearing the end of its life. 行星状星云一个由来自中心濒临死亡恒星所释放出的气体组成的正在膨胀的星云。 cdn.astronomy.com.cn 8. Officially known as PN G75. 5+1. 7, the Soap Bubble is an example of a planetar...
Planetary nebulaeare formed when a star dies and create dramatic formations of radiating cosmic gas. Some great examples of planetary nebulae in the night sky include the Ring Nebula, the Dumbbell Nebula, and theHelix Nebula. Planetary Nebulae involves a low-mass star entering the final stage of...
Betelgeuse is profusely losing mass due to a powerful solar wind and there will be shells of gas and dust moving away from the star similar to a planetary nebula, but there is no super hot remnant white dwarf or neutron star present in the center to light it up. So we don’t see ...

of star that produced the explosion. With a Supernova Remnant, the star producing the explosion would be about eight or more times our sun. Anything smaller would create a planetary nebula. Ref:Cornell. The image is of theCrab Nebula, which despite its name, is not inCancerbut is in...
NGC 2438 is aplanetary nebula, formed after the death of a Sun-like star. The medium-sized star would have expelled its outer layers of gas into space as it died, leaving behind a white-dwarf core. A halo of glowing gas over 4.5 light-years across surrounds the nebula’s brighter inner...

Our Sun will become a planetary nebula. Some of our bodies' elements could only have been created through the extreme heat of a dying star, so a star's death was imperative.Goldilocks Zone The Goldilocks Zone is a region of space from a star which is neither too hot nor too cold for ...
Finallythey shrink again,leaving behind most of their gas.This gas forms a beautiful cloud around the star called aplanetary nebula(行星状星云).When will the Sun expand into a giant, and thenshrink leaving behind a planetary nebula?Don't worry. The Sun is only about 5 billion yearsold. ...
