A planetary nebula is a phenomenon that occurs when a small to medium-sized star approaches the end of its life cycle. While very large stars end their lives in an explosion of light called asupernova, smaller stars fade out more gradually as gases and radiation exit their core. The first...
What is a Planetary Nebula? The term Planetary Nebula is one type of Nebulae (Not nebulas), which are large clouds of ice and dust that have been created in the aftermath of the death of a star. Although their name includes “planet”, they are nothing to do with planets. They do ...

Stars like the sun end their lives as highly compact white dwarfs, but as they shrink down into this phase they release clouds of gas which form a so-called "planetary nebula". This is a rather misleading name, because such nebula have nothing to do with planets. Related stories — The ...

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...

However, we did detect one interesting object: an OH 1612 MHz maser in the young planetary nebula NGC 6302. This nebula may be in a brief evolutionary stage, similar to the young and compact planetary nebula Vy 2-2 where OH has already been detected....

The Nebula is blue because dust that causes their light tends to be more efficiently reflected. The same colour physics applied to Witch-Head also explains why our sky is blue. Ref:N.A.S.A. Planetary Nebula / Ghost Nebula Despite its name,planetary nebulae isn't anything to do with plane...
