"The M17 region brings to mind images of other spiral galaxies where the leading edges of the arms appear blue, with young O stars, but the trailing edges are still dark, with obscuring dust like in M17 SWex," adds Povich.

5% of male Ashkenazim were found to belong to R-M17, the dominant Y chromosome haplogroup in Eastern Europeans, suggesting possible gene flow.
Located in the constellation Sagittarius, M17 is an open cluster of about 35 stars within a cloud of gas. As with M16, the hot stars cause the nebula to shine brightly.

"One of the most impressive objects to me is the Swan Nebula M17 as seen with the 'BinoViewer', sitting back on a lounge-chair and spending time enjoying all the swirls and deep contrast.
M17 (NGC 6618), the "Swan Nebula" or the "Omega Nebula", and occasionally known as the "Horseshoe Nebula". This nebula resembles the tail of a comet: a bright diffuse trail of light with a bit of a hook on it. It is about 5000 light years away.
Named after the last letter in the Greek alphabet, it is also called M17 or NGC 6618. This is another emission nebula, with young hot protostars that can be observed only in infrared wavelengths.
