How are diffuse nebulae different from other nebulae?
After all, diffuse nebulae are not just clouds of gas and dust in space in which stars are born, but another type called planetary nebula are those places created when a star reaches its final evolutionary state, and changes from a red giant to a white dwarf, in the process shedding its outer layers of gas to form a planetary nebula.
Which is the least complex nebula in the universe?
Located just 7.5 degrees away from the Pole Star, this is one of the least complex planetary nebulae known, with an almost perfectly spherical morphology. The progenitor star appears to have been an asymptotic red giant, the remains of which can be seen even with modest amateur equipment.
What kind of Nebula is a protoplanetary nebula?
A protoplanetary nebula (PPN) is an astronomical object at the short-lived episode during a star’s rapid stellar evolution between the late asymptotic giant branch (LAGB) phase and the following planetary nebula (PN) phase.
