Re: NGC 6164

The outer shell, bipolar nature is great.

So that central star is very young, and therefore very blue?

This is an image of NGC 6164. It is an emission nebula about 4,200 light years away in the constellation Norma. The nebula was created by a hot O-type star about 40 times as massive as the Sun. The star can be seen in the center of the image and is a mere 3-4 million years old. In another 3-4 million years, this star will end its life as a supernova. By comparison, our Sun is almost 5 billion years old and has another 5 billion years left in its lifetime. This nebula has a bipolar symmetry similar to some planetary nebulae and has an outer halo expanding into the interstellar medium.

Comments and suggestions welcomed.
