  M17
M17, the Swan Nebula, is one of the most special summertime sites that you could hope to see.
With a telescope of even small and moderate apertures, M17 is quite beautiful, with the brighter portion of the nebula tracing the shape of a swan.
M17 is also known as the "Omega Nebula," a name given to it because its overall shape seems to resemble the Greek letter.

 Stack Computers: 4.3 ARCHITECTURE OF THE MISC M17
The M17 provides five signal pins to indicate which memory space is active: data stack, return stack, code space, A buffer, and B buffer.
The M17 takes two clock cycles for each instruction: one clock cycle to load the instruction from program memory, and another clock cycle to perform the operation while doing a read from or write to one of the stacks in program memory.
The biggest difference between the M17 and the Canonical Stack Machine described in Chapter 3 is that the M17's stack memory and program memory accesses use the same bus, and may reside in the same memory chips.

 M17, The Swan Nebula   (Site not responding. Last check: 2007-10-17)
M17 (NGC 6618) is an Emission Nebula and Open Cluster located in the constellation of Sagittarius.
M17 is known also as the Swan, Omega, or Horseshoe nebula, and was first discovered by Philippe Loys de Cheseaux in 1746.
M17, along with M42, are the two brightest galactic nebula visible to observers in the mid-northern latitudes.

 M17 - Omega Nebula   (Site not responding. Last check: 2007-10-17)
M17, the Omega or Swan Nebula, is a region of star formation and shines by excited emission, caused by the ultraviolet light radiation of young stars which have formed inside the nebula.
The pink and nearly white colors near the center is caused by a mixture of emission by the hydrogen and reflected starlight by the dust within the nebula.
M17 was discovered by de Cheseaux in 1764, and Charles Messier independently observed it and listed it in his famous catalog in the same year.

 M17
The heating in M17, for both high density and low density tracers, is dominated by the M17 OB stellar cluster, as is evidenced by the regular decline in temperature away from the interface region seen in both tracers (see Section 2.4.2).
However, the geometry of these sources is quite different, in M17 the ionization front/molecular cloud interface is perpendicular to the plane of the sky, as compared to in Orion where the H II region appears in front of the molecular cloud.
Therefore, it is plausible to expect that the CO emission in M17 will not exhibit all of the complexities seen in Orion but will decrease in a relatively simple fashion with distance from the heating source.

 M17, The Omega Nebula
After M42, the Omega Nebula is the brightest galactic nebula in the northern sky and is located just to the north of M24 (the small Sagittarius Star cloud) in the summer Milky Way, and is about 5,000 to 6,000 light years distant.
M17 can be easily seen in binoculars and in a telescope the brighter portion of the nebula has the very distinctive shape of a swan, or the greek letter Omega, or a horseshoe, hence its popular names.
As with most bright emission nebulae, M17 is a large concentration of hydrogen gas and dust in space.

 M17 The Swan Nebula
M17, also called the Swan Nebula and sometimes the Omega Nebula, is a region of star formation and shines by excited emission caused by the high-energy radiation of young stars.
While the bright nebula seems to be roughly 15 light years across, the total gaseous cloud, including low-luminosity material, extends to at least 40 light years.
M17 is estimated to be 5,000 to 6,000 light years distant.

Nine-speed chains snap more than their 8-speed ancestors, low-spoke count wheels seem to snatch at sticks, rotors warp at the weirdest moments and many of the things that you thought were tight seem to wobble loose of their own accord.

La découverte de M17 par De Chéseaux ne fut pas largement diffusée, de sorte que Charles Messier l'a redécouverte indépendamment et l'a rentrée dans son catalogue le 3 Juin 1764.

However, the nebulosity is very bright, so the exciting stars must be hidden within the cloud, an idea confirmed by the infrared brightness of the nebula.
As well as exciting the nebula we can see, the embedded stars heat the dust that surrounds them, so M17 is one of the brightest objects in the infrared sky.
