NGC 6674 - A Gem Amongst
Jewels
Barred Spiral Galaxy
NGC 6674 is truly a gem amongst jewels. It is far, far behind a
very densely populated area of the sky in our galaxy. Over a
thousand "foreground" stars can be seen here that are part of
our own galaxy, the Milky Way. The color of the foreground stars
range from very hot blue and white stars to cooler yellow,
orange and red stars. Note the extremely red star in the far low
right of the image. NGC 6674 appears behind these stars in a
stunning optical illusion that makes it appear to be part of
them. Its own star systems are also composed of some 200 - 400
billion stars of varying colors. Clearly visible is a distinct
barred structure with a nearly complete inner ring connecting
the two bars. Stars in this area of the galaxy are likely older
and redder. Stars in the arms are younger indicating more recent
formation out of the dust and gas, perhaps perturbed by a
relatively recent merger with another galaxy. At the center of
this galaxy as with most galaxies is one or more supper massive
black holes influencing the galactic structure and rotation. If
you look closely you may see several satellite galaxies in this
image. Also visible in the upper left is a partial blue circle
caused by a very bright star just out of the image. That very
bright star GSC 2111:330 is magnitude 7.8, or more than 5 times
fainter than what the human eye can see. The brightest star in
this image (cut off at far left) is magnitude 10.5 or about 60
times fainter than we can see with our eyes. Note you may click
