Info |
NGC 6559
(bottom) is located in the
constellation of Sagittarius. It is probably associated with the better
known M8 & M20 nebula complex, but separated by dark dust lanes. The over
all red hue is due to glowing hydrogen gas energised by the radiation of
hot young stars. The blue regions (in both Ngc 6559 & IC 1274/5)
are from dust reflected starlight.
The dust is also
evident by the many odd shaped dark lanes and isolated patches. It is
approximately 5,000 L.y. away. |
