A halo of NGC 6164
The attractive emanation nebula NGC 6164 was created by a strange, hot and bright star of type O , about 40 times more massive than the Sun Vista here in the center of the cosmic cloud, the star has an age of 3-4000000 years, within three or four million years will end its life in a supernova explosion .
With a diameter of about 4 light years away, the nebula has a bipolar symmetry,
making it look like the planetary nebulae more familiar (gaseous shrouds around sunlike stars that are dying).
As many planetary nebulae, NGC 6164 also has a faint halo and extensive, as seen in this telescope deep.
The halo material, which expands in the interstellar medium surrounding, surely comes from an earlier phase of the star active type O.
This gorgeous skyscape is a visual composition narrowband data, highlighting the glowing gas, and broadband data stellar environment.
NGC 6164 is 4,200 light years away in the southern constellation Norma.
