Object description:
Our image shows a 2 star mosaic of the
ARA OB1 association. Starting on the left
side of the image with the open star cluster NGC
6193 to the right side of the very faint H-II region
GN 16.25.3.01. About in the center of the image is
the bipolar Wolf Rayet nebula NGC 6164/65.
The extremely young and hot stars
of NGC 6191 and their intense UV radiation provide the energy for ionization,
which stimulates the H-II region of NGC 6188 to glow. The whole region lies at
a distance of 3800 to 4000 light-years from the solar system. The bright star
Epsilon Norma, in the upper right of the image, is much closer to the solar
system at a distance of 530 light-years. It is a physical double star system
(distance 23 arc seconds), whose main component is spectroscopically double, so
it is a triple star system. The three stars are very young, about 50 million
years old.
We have imaged this
interesting region with different focal lengths. There you will also find
detailed object descriptions.
