In this classic Hubble image from 2000, the planetary nebula IC 418 glows like a multifaceted jewel with enigmatic patterns.
Because it is located relatively close, only 219 parsecs away,the details of the internal structures of the planetary nebula can be revealed.
Take this picture, for example, it shows a planetary nebula, which is the remains of a star that was ripped apart by a violent explosion.
Such stars eventually blow off the material of their outer layers,which creates an expanding shell of gas called a planetary nebula.

Long exposures have shown that this planetary nebula has an extended double halo,[6] while the more easily visible portion probably dates to the death of the red giant in its center.[2].
The data said you could get bright planetary nebulae from low mass stars like the sun,[while] the models said that was not possible, anything less than abouttwice the mass of the sun would give a planetary nebula too faint to see.”.
