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 on the image to see a larger version
showing more details. The stats for NGC 6674 are as follows:
Coordinates RA: 18h 38m 33.8s Dec: +25° 22' 30", magnitude: 13.0, size:
4.0'x2.2', and galaxy class: SB(r)b.
