Description

A bubble in its bubble

Most spherical nebulae are the result of the death of a star, but this one is caused by the total opposite.

At the heart of this nebula, a young massive star is blasting the gas and dust formed during its antepartum phase. That gas on its turn is excited by the strong radiation coming from the new star, and glows as a result.

I live in a bubble too.
