What Is A Planetary Nebula ?
A planetary nebula is formed when a star is unable to support its size and forma and starts creating fusion at its center. The gravity that is extended on the star starts affecting it and starts heating up the inner parts of it. The severe condensation and over heating will split the star and drive half of it away into the stellar wind. |
This kind of process can take place over a thousand years. When the whole process is complete, the remnants glow because of the heat and the distant gases. Such a nebula is called a planetary nebula.More...

A nebula is formed when basically a giant star supernova’s itself on a dwarf star. Nebula is nothing but a formation of plasmid matter, cloud of dust, particles and various gases.More...
The crab nebula is a part of the Taurus constellation and is a result of the supernova explosion. Astronomers believe that it formed due to the supernova explosion and the pulsar wind of the nebula within the constellation of Taurus. The nebula was first observed by John Bevis in 1731, and the findings also correspond to the findings of Chinese and Arab astronomers in 1054.More...
For a very long time in the ancient times, people thought that the Earth as the center of the universe and the earth never moved. Several constellations were discovered and various theories were established based on what we could see with the naked eye without using any of these complicated telescopes that we have today.More...
