The diffuse emission nebula lies near the constellation’s northern border with <a href="https://www.constellation-guide.com/constellation-list/scutum-constellation/">Scutum</a>, at a distance of 5,000 to 6,000 light years from Earth. It has an apparent magnitude of 6.0.<br /> <span id="more-257"></span><br /> Also known as the Swan Nebula, Lobster Nebula, Horseshoe Nebula and Checkmark Nebula, the Omega Nebula is one of the brightest star-forming nebulae of the Milky Way. Its designation in the New General Catalogue is NGC 6618. With a total mass of roughly 800 solar masses, M17 is also one of the most massive H II regions of our galaxy. The nebula occupies an area roughly 15 light years in diameter and is part of a larger cloud, which is about 40 light years in diameter.</p> <p>Messier 17 is located in the Sagittarius Arm of the Milky Way, the next inward spiral arm to our own, and may be part of the same giant cloud complex as its close neighbour, <a href="https://www.messier-objects.com/messier-16-eagle-nebula/">Messier 16</a> (the Eagle Nebula), located in the <a href="https://www.constellation-guide.com/constellation-list/serpens-constellation/">constellation Serpens</a>.</p> <p>The Omega Nebula is just on the limit of naked eye detection in good conditions, with clear, dark skies and no light pollution. It is best observed in low-powered telescopes and binoculars. It lies in the same binocular field of view as <a href="https://www.messier-objects.com/messier-16-eagle-nebula/">Messier 16</a> and <a href="https://www.messier-objects.com/messier-18/">Messier 18</a>, a faint open cluster in <a href="https://www.constellation-guide.com/constellation-list/sagittarius-constellation/">Sagittarius</a>.</p> <figure id="attachment_2047" aria-describedby="caption-attachment-2047" style="width: 600px" class="wp-caption aligncenter"><a href="https://www.messier-objects.com/wp-content/uploads/2015/04/Messier-17-ESO.jpg"><img fetchpriority="high" decoding="async" class="wp-image-2047" src="https://www.messier-objects.com/wp-content/uploads/2015/04/Messier-17-ESO.jpg" alt="messier 17,omega nebula,m17,m17 nebula" width="600" height="561" srcset="https://www.messier-objects.com/wp-content/uploads/2015/04/Messier-17-ESO.jpg 1280w, https://www.messier-objects.com/wp-content/uploads/2015/04/Messier-17-ESO-300x280.jpg 300w, https://www.messier-objects.com/wp-content/uploads/2015/04/Messier-17-ESO-1024x957.jpg 1024w" sizes="(max-width: 600px) 100vw, 600px" /></a><figcaption id="caption-attachment-2047" class="wp-caption-text">This new image of the rose-coloured star forming region Messier 17 was captured by the Wide Field Imager on the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in Chile.

The painting-like image shows vast clouds of gas and dust illuminated by the intense radiation from young stars. The image shows a central region about 15 light-years across, although the entire nebula is even larger, about 40 light-years in total. Messier 17 is in the constellation of Sagittarius (the Archer), about 6000 light-years from Earth. It is a popular target for amateur astronomers, who can obtain good quality images using small telescopes.<br />These deep VLT observations were made at near-infrared wavelengths with the ISAAC instrument. The filters used were J (1.25 µm, shown in blue), H (1.6 µm, shown in green), and K (2.2 µm, shown in red). In the centre of the image is a cluster of massive young stars whose intense radiation makes the surrounding hydrogen gas glow. To the lower right of the cluster is a huge cloud of molecular gas. At visible wavelengths, dust grains in the cloud obscure our view, but by observing in infrared light, the glow of the hydrogen gas behind the cloud can be seen shining faintly through. Hidden in this region, which has a dark reddish appearance, the astronomers found the opaque silhouette of a disc of gas and dust. Although it is small in this image, the disc has a diameter of about 20 000 AU, dwarfing our Solar System (1 AU is the distance between the Earth and the Sun). It is thought that this disc is rotating and feeding material onto a central protostar — an early stage in the formation of a new star. Credit: ESO/R.

Additionally, there are more than a thousand stars in the process of forming in the nebula’s outer regions.</p> <p>The young stars in M17 do not readily appear in visible light images, but are hidden within the nebula’s dust and gas. Even the light of the 35 brightest stars is obscured by the surrounding nebulosity.</p> <p>Messier 17 has a similar geometry to <a href="https://www.messier-objects.com/messier-42-orion-nebula/">Messier 42</a>, the famous Orion Nebula, but unlike <a href="https://www.messier-objects.com/messier-42-orion-nebula/">M42</a>, which appears face-on, M17 is seen edge-on.

The cloud, located about 6,000 light-years away in the constellation Sagittarius, is dominated by a central group of massive stars — the most massive stars in the region (see yellow circle). These central stars give off intense flows of expanding gas, which rush like rivers against dense piles of material, carving out the deep pocket at center of the picture. Winds from the region’s other massive stars push back against these oncoming rivers, creating bow shocks like those that pile up in front of speeding boats.<br />Three of these bow shocks are labeled in the magnified inset. They are composed of compressed gas in addition to dust that glows at infrared wavelengths Spitzer can see. The smiley-shaped bow shocks curve away from the stellar winds of the central massive stars. This picture was taken with Spitzer’s infrared array camera. It is a four-color composite, in which light with a wavelength of 3.6 microns is blue; 4.5-micron light is green; 5.8-micron light is orange; and 8-micron light is red. Dust is red, hot gas is green and white is where gas and dust intermingle. Foreground and background stars appear scattered through the image. Credit: NASA/JPL-Caltech/M.

M17, also known as the Omega or Swan Nebula, is located about 5500 light-years away in the constellation Sagittarius. The wave-like patterns of gas have been sculpted and illuminated by a torrent of ultraviolet radiation from young, massive stars, which lie outside the picture to the upper left. The glow of these patterns accentuates the three-dimensional structure of the gases. The ultraviolet radiation is carving and heating the surfaces of cold hydrogen gas clouds. The warmed surfaces glow orange and red in this photograph. The intense heat and pressure cause some material to stream away from those surfaces, creating the glowing veil of even hotter greenish gas that masks background structures. The pressure on the tips of the waves may trigger new star formation within them. The image, roughly 3 light-years across, was taken May 29-30, 1999, with the Wide Field Planetary Camera 2.

Very much extended, with a hook on the preceding [western] side; the nebulosity of the milky kind; several stars visible in it, but they seem to have no connection with the nebula, which is far more distant. I saw it only through short intervals of flying clouds and haziness; but the extent of the light including the hook is above 10′. I suspect besides, that on the following [eastern] side it goes on much farther and diffuses itself towards the north and south. It is not of equal brightness throughout and has one or more places where the milky nebulosity seems to degenerate into the resolvable [mottled] kind; such a one is that just following the hook towards the north. Should this be confirmed on a very fine night, it would bring on the step between these two nebulosities which is at present wanting, and would lead us to surmise that this nebula is a stupendous stratum of immensely distant fixed stars, some of whose branches come near enough to us to be visible as a resolvable nebulosity, while the rest runs on to so great a distance as only to appear under the milky form.</p></blockquote> <figure id="attachment_295" aria-describedby="caption-attachment-295" style="width: 600px" class="wp-caption aligncenter"><a href="https://www.messier-objects.com/wp-content/uploads/2015/04/Omega-Nebula-Herschel.jpg"><img loading="lazy" decoding="async" class="wp-image-295" src="https://www.messier-objects.com/wp-content/uploads/2015/04/Omega-Nebula-Herschel-1024x880.jpg" alt="messier 17 sketch" width="600" height="516" srcset="https://www.messier-objects.com/wp-content/uploads/2015/04/Omega-Nebula-Herschel-1024x880.jpg 1024w, https://www.messier-objects.com/wp-content/uploads/2015/04/Omega-Nebula-Herschel-300x258.jpg 300w, https://www.messier-objects.com/wp-content/uploads/2015/04/Omega-Nebula-Herschel.jpg 1281w" sizes="auto, (max-width: 600px) 100vw, 600px" /></a><figcaption id="caption-attachment-295" class="wp-caption-text">Omega Nebula sketch by John Herschel, 1833</figcaption></figure> <p>John Herschel, William Herschel’s son, was the one who noted the nebula’s resemblance to the Greek capital letter omega (Ω). He was the first to accurately draw M17 in 1833 and published his drawing as part of a series of sketches of nebulae in 1836. He wrote:</p> <blockquote><p>The figure of this nebula is nearly that of the Greek capital Omega, somewhat distorted and very unequally bright. It is remarkable that this is the form usually attributed to the <a href="https://www.messier-objects.com/messier-42-orion-nebula/">great nebula in Orion</a>, though in that nebula I confess I can discern no resemblence whatever to the Greek letter. Messier perceived only the bright preceding branch of the nebula now in question, without any of the attached convolutions which were first noticed by my Father. The chief peculiarities which I have observed in it are, 1st, the resolvable knot in the following portion of the bright branch, which is in a considerable degree insulated from the surrounding nebula; strongly suggesting the idea of an absorption of nebulous matter; and 2ndly, the much feebler and smaller knot in the north preceding end of the same branch, where the nebula makes a sudden bend at an acute angle. With a view to a more exact representation of this curious nebula, I have at different times taken micrometrical measures of the relative places of the stars in and near it, by which, when laid down on the chart, its limits may be traced and identified, as I hope soon to have better opportunity to do than its low situation in this latitudes will permit.</p></blockquote> <figure id="attachment_296" aria-describedby="caption-attachment-296" style="width: 600px" class="wp-caption aligncenter"><a href="https://www.messier-objects.com/wp-content/uploads/2015/04/Messier-17-Lassell.jpg"><img loading="lazy" decoding="async" class="wp-image-296" src="https://www.messier-objects.com/wp-content/uploads/2015/04/Messier-17-Lassell-986x1024.jpg" alt="messier 17 drawing" width="600" height="623" srcset="https://www.messier-objects.com/wp-content/uploads/2015/04/Messier-17-Lassell.jpg 986w, https://www.messier-objects.com/wp-content/uploads/2015/04/Messier-17-Lassell-289x300.jpg 289w" sizes="auto, (max-width: 600px) 100vw, 600px" /></a><figcaption id="caption-attachment-296" class="wp-caption-text">Messier 17, as drawn by William Lassell in 1862.

Messier in 1764, and registered as a train of light without stars, about 5′ or 6′ in extent. As with the two preceding objects [<a href="https://www.messier-objects.com/messier-16-eagle-nebula/">M16</a> and <a href="https://www.messier-objects.com/messier-18/">M18</a>], its place hangs upon Mu Sagittarii, from which it bears north-by-east, about 5deg distant, in the line towards Epsilon Aquilae. In my telescope charged with a moderate [magnification] eye-piece, this curious nebula is well seen, though not to the extent of convolution figured by Sir John Herschel. A magnificient, arched, and irresolvable luminosity occupies more than one third of the area, in a splendid group of stars, among which are Nos. 38 and 43, Hora XVIII. of Piazzi; they are principally from the 9th to the 12th magnitudes, reaching more or less all over the field, somewhat in the accompanying form.</p></blockquote> <h3 style="text-align: center;">FACTS</h3> <table> <tbody> <tr> <td width="619"><strong>Object: Nebula </strong></td> </tr> <tr> <td width="619"><strong>Type: Emission </strong></td> </tr> <tr> <td width="619"><strong>Designations: Omega Nebula, Messier 17, M17, NGC 6618, Sharpless 45, RCW 160, Gum 81, Collinder 377, LBN 60, Swan Nebula, Lobster Nebula, Horseshoe Nebula, Checkmark Nebula</strong></td> </tr> <tr> <td width="619"><strong>Constellation: <a href="https://www.constellation-guide.com/constellation-list/sagittarius-constellation/">Sagittarius</a> </strong></td> </tr> <tr> <td width="619"><strong>Right ascension: 18h 20m 26s </strong></td> </tr> <tr> <td width="619"><strong>Declination: -16°10’36” </strong></td> </tr> <tr> <td width="619"><strong>Distance: 5,000-6,000 light years (1,533-1,840 parsecs) </strong></td> </tr> <tr> <td width="619"><strong>Apparent magnitude: +6.0 </strong></td> </tr> <tr> <td width="619"><strong>Apparent dimensions: 11′ </strong></td> </tr> </tbody> </table> <h3 style="text-align: center;">LOCATION</h3> <figure id="attachment_287" aria-describedby="caption-attachment-287" style="width: 600px" class="wp-caption aligncenter"><a href="https://www.messier-objects.com/wp-content/uploads/2015/04/Messier-17-location.png"><img loading="lazy" decoding="async" class="wp-image-287" src="https://www.messier-objects.com/wp-content/uploads/2015/04/Messier-17-location.png" alt="omega nebula location,find messier 17" width="600" height="739" srcset="https://www.messier-objects.com/wp-content/uploads/2015/04/Messier-17-location.png 831w, https://www.messier-objects.com/wp-content/uploads/2015/04/Messier-17-location-244x300.png 244w" sizes="auto, (max-width: 600px) 100vw, 600px" /></a><figcaption id="caption-attachment-287" class="wp-caption-text">Messier 17 location.

It is based on exposures obtained on August 15, 2000, with the SOFI multi-mode instrument at the ESO 3.6-m New Technology Telescope (NTT) at La Silla. In this image, young and heavily obscured stars are recognized by their red colour. Bluer objects are either foreground stars or well-developed massive stars whose intense light ionizes the hydrogen in this region. The diffuse light that is visible nearly everywhere in the photo is due to emission from hydrogen atoms that have (re-)combined from protons and electrons. The dark areas are due to obscuration of the light from background objects by large amounts of dust – this effect also causes many of those stars to appear quite red. A cluster of young stars in the upper-left part of the photo, so deeply embedded in the nebula that it is invisible in optical light, is well visible in this infrared image. Technical information : The exposures were made through three filtres, J (at wavelength 1.25 µm; exposure time 5 min; here rendered as blue), H (1.65 µm; 5 min; green) and Ks (2.2 µm; 5 min; red); an additional 15 min was spent on separate sky frames. The seeing was 0.5 – 0.6 arcsec. The objects in the uppermost left corner area appear somewhat elongated because of a colour-dependent aberration introduced at the edge by the large-field optics. The sky field shown measures approx. 5 x 5 arcmin 2 (corresponding to about 3% of the full moon). North is up and East is left.
