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.
