Overview: NGC 7606 is a
spiral
galaxy located in the direction of the constellation
Aquarius the “water-carrier.” The constellation likely dates
to ancient Babylon whose god Ea is often seen as a star-figure
holding an overflowing vase or cup. NGC 7606 is about 100 ± 20
million light years from Earth which yields a size of about
165,000 light years across or about 65% larger than our own
milky way galaxy. It is moving over 2000 kilometers per second
away from earth.
Details: NGC 7606 was discovered and cataloged by
William
Herschel on September 28, 1785 and is a fairly typical
non-barred spiral galaxy as seen inclined. If it were seen
face-on it would form a circular image, but like a dinner plate
tilted toward us, it appears oval or elliptical in shape. It
does not have a bar connecting its arms, but it does have an
inner right partially visible here in the inset. The
galaxy has two separate galactic arms that extend completely
around its nucleus 1-2 times. Like most spiral galaxies it’s
center nucleus does contain a
supermassive black hole of some 20 million solar masses (1
solar mass = mass of our sun).
Annotations. The
above image shows annotations when hovering over the image. The
galactic nucleus is clearly visible and enlarged here and the
galactic ring that partially envelops the central bulge is
clearly visible. Also shown is an enlarged inset of the 17.2
magnitude galaxy PGC 1003486 which appears to be a barred spiral
or a significantly disturbed spiral galaxy and over 30,000 times
fainter than the faintest star visible to the naked eye.
Below Images: In the first image below, the same image
has been processed to remove all foreground stars as these stars
are all within our own Galaxy. This is what the view would
appear like if we left our galaxy looking outward. Using a mouse
to hover over the image comma brings all of the stars back. The
second image below shows an enlarged and cropped versions of the
galaxy.
