This new view of the Orion nebula highlights fledgling stars hidden in the gas and clouds. It shows infrared observations taken by NASA's Spitzer Space Telescope and the European Space Agency's Herschel mission, in which NASA plays an important role.
A star forms as a clump of this gas and dust collapses, creating a warm glob of material fed by an encircling disk. These dusty envelopes glow brightest at longer wavelengths, appearing as red dots in this image. In several hundred thousand years, some of the forming stars will accrete enough material to trigger nuclear fusion at their cores and then blaze into stardom.
The nebula is found below the three belt stars in the famous constellation of Orion the Hunter, which appears at night in northern latitudes during fall and then throughout winter. At a distance of around 1,500 light-years away from Earth, the nebula cannot quite be seen with the naked eye. Binoculars or a small telescope, however, are all it takes to get a good look in visible light at this stellar factory.
Spitzer is designed to see shorter infrared wavelengths than Herschel. By combining their observations, astronomers get a more complete picture of star formation. The colors in this image relate to the different wavelengths of light, and to the temperature of material, mostly dust, in this region of Orion. Data from Spitzer show warmer objects in blue, with progressively cooler dust appearing green and red in the Herschel datasets. The more evolved, hotter embryonic stars thus appear in blue.
The combined data traces the interplay of the bright, young stars with the cold and dusty surrounding clouds. A red garland of cool gas also notably runs through the Trapezium, the intensely bright region that is home to four humungous blue-white stars, and up into the rich star field.
Infrared data at wavelengths of 8.0 and 24 microns from Spitzer are rendered in blue. Herschel data with wavelengths of 70 and 160 microns are represented in green and red, respectively.
This wide-field view of the Orion Nebula (Messier 42), lying about 1350 light-years from Earth, was taken with the VISTA infrared survey telescope at ESO’s Paranal Observatory in Chile. The new telescope’s huge field of view allows the whole nebula and its surroundings to be imaged in a single picture and its infrared vision also means that it can peer deep into the normally hidden dusty regions and reveal the curious antics of the very active young stars buried there. This image was created from images taken through Z, J and Ks filters in the near-infrared part of the spectrum. The exposure times were ten minutes per filter. The image covers a region of sky about one degree by 1.5 degrees. ASU-IPF-3071
Great Orion Nebula (M42, M43) and Running Man Nebula (NGC 1973/5/7)

A re-processing of old data (omitting the 60 second exposures, which didn't add much). There's a bit more noise come through but there's a hell of a lot more detail showing and all in all I think I'm pretty pleased with the upgrade at such a low amount of time!

This dramatic image offers a peek inside a cavern of roiling dust and gas where thousands of stars are forming. The image, taken by the Advanced Camera for Surveys (ACS) aboard NASA/ESA Hubble Space Telescope, represents the sharpest view ever taken of this region, called the Orion Nebula. More than 3,000 stars of various sizes appear in this image. Some of them have never been seen in visible light. These stars reside in a dramatic dust-and-gas landscape of plateaus, mountains, and valleys that are reminiscent of the Grand Canyon. The Orion Nebula is a picture book of star formation, from the massive, young stars that are shaping the nebula to the pillars of dense gas that may be the homes of budding stars. The bright central region is the home of the four heftiest stars in the nebula. The stars are called the Trapezium because they are arranged in a trapezoid pattern. Ultraviolet light unleashed by these stars is carving a cavity in the nebula and disrupting the growth of hundreds of smaller stars. Located near the Trapezium stars are stars still young enough to have disks of material encircling them. These disks are called protoplanetary disks or "proplyds" and are too small to see clearly in this image. The disks are the building blocks of solar systems. The bright glow at upper left is from M43, a small region being shaped by a massive, young star's ultraviolet light. Astronomers call the region a miniature Orion Nebula because only one star is sculpting the landscape. The Orion Nebula has four such stars. Next to M43 are dense, dark pillars of dust and gas that point toward the Trapezium. These pillars are resisting erosion from the Trapezium's intense ultraviolet light. The glowing region on the right reveals arcs and bubbles formed when stellar winds - streams of charged particles ejected from the Trapezium stars - collide with material. The faint red stars near the bottom are the myriad brown dwarfs that Hubble spied for the first time in the nebula in visible light. Sometimes called "failed stars," brown dwarfs are cool objects that are too small to be ordinary stars because they cannot sustain nuclear fusion in their cores the way our Sun does. The dark red column, below, left, shows an illuminated edge of the cavity wall. The Orion Nebula is 1,500 light-years away, the nearest star-forming region to Earth. Astronomers used 520 Hubble images, taken in five colours, to make this picture. They also added ground-based photos to fill out the nebula. The ACS mosaic covers approximately the apparent angular size of the full moon. The Orion observations were taken between 2004 and 2005.
Narrowband emission line image mapped more or less to natural colorspace, S-II = red, Ha = yellowish red, O-III greenish blue, Hb = blue.
Using only the narrowband leaves all the fantastic reflection nebula areas out, but it's still a very pretty nebula at emission lines.
The Great Nebula in Orion is featured in this sweeping image from NASAs Wide-field Infrared Survey Explorer, or WISE. The constellation of Orion is prominent in the evening sky throughout the world from about December through April of each year. The Orion Nebula (also catalogued as Messier 42) is located in the sword of Orion, hanging from his famous belt of three stars. The star cluster embedded in the nebula is visible to the unaided human eye as a single star, with some fuzziness apparent to the most keen-eyed observers. Because of its prominence, cultures all around the world have given special significance to Orion. The Maya of Mesoamerica envision the lower portion of Orion, his belt and feet (the stars Saiph and Rigel), as being the hearthstones of creation, similar to the triangular three-stone hearth that is at the center of all traditional Maya homes. The Orion Nebula, lying at the center of the triangle, is interpreted by the Maya as the cosmic fire of creation surrounded by smoke.
The metaphor of a cosmic fire of creation is apt. The Orion Nebula is an enormous cloud of dust and gas where vast numbers of new stars are being forged. It is one of the closest sites of star formation to Earth and therefore provides astronomers with the best view of stellar birth in action. Many other telescopes have been used to study the nebula in detail, finding wonders such as planet-forming disks around newly forming stars. WISE was an all-sky survey giving it the ability to see these sites of star formation in a larger context. This view spans more than six times the width of the full Moon, covering a region nearly 100 light-years across. In it, we see the Orion Nebula surrounded by large amounts of interstellar dust, colored green.
Astronomers now realize that the Orion Nebula is part of the larger Orion molecular cloud complex, which also includes the Flame Nebula. This complex in our Milky Way Galaxy is actively making new stars. It is filled with dust warmed by the light of the new stars within, making the dust glow in infrared light.
Color in this image represents specific infrared wavelengths. Blue represents light emitted at 3.4-micron wavelengths and cyan (blue-green) represents 4.6 microns, both of which come mainly from hot stars. Relatively cooler objects, such as the dust of the nebulae, appear green and red. Green represents 12-micron light and red represents 22-micron light.
Taken in Houston, TX. Sky glow diminished the apparent size of the Orion Nebula quite a bit, but the main feature can still be seen.

This image from NASA's Spitzer Space Telescope shows what lies near the sword of the constellation Orion -- an active stellar nursery containing thousands of young stars and developing protostars. Many will turn out like our sun. Some are even more massive. These massive stars light up the Orion nebula, which is seen here as the bright region near the center of the image..
.
To the north of the Orion nebula is a dark filamentary cloud of cold dust and gas, over 5 light-years in length, containing ruby red protostars that jewel the hilt of Orion's sword. These are the newest generation of stars in this stellar nursery, and include the protostar HOPS 68, where Spitzer spotted tiny green crystals in a surrounding cloud of gas.

Another shot at the star cluster Pleiades. Now I was able to capture some hints of the blue nebula surrounding the Seven Sisters.
The brownish glow in the lower half of the picture are actually clouds moving across the sky during the 2-minute exposure for this shot, and the blue-green glow is actually the light pollution that is being reflected by the clouds.
Nikon D300 shot of the Orion Nebula --camera was mounted to my 10" Meade LX200 telescope. (f6.3 focal reducer attached)
This is a "minor" composite shot... I pulled a little bit of a short-exposure photo (that captured the Trapezium) into the longer exposure photograph that got the finer details in the outer parts of the nebula.

This infrared image from NASA's Spitzer Space Telescope shows the Orion nebula, our closest massive star-making factory, 1,450 light-years from Earth. The nebula is close enough to appear to the naked eye as a fuzzy star in the sword of the popular hunter constellation.
The nebula itself is located on the lower half of the image, surrounded by a ring of dust. It formed in a cold cloud of gas and dust and contains about 1,000 young stars. These stars illuminate the cloud, creating the beautiful nebulosity, or swirls of material, seen here in infrared.
This image shows infrared light captured by Spitzer's infrared array camera. Light with wavelengths of 8 and 5.8 microns (red and orange) comes mainly from dust that has been heated by starlight. Light of 4.5 microns (green) shows hot gas and dust; and light of 3.6 microns (blue) is from starlight.
Above the Orion nebula, where the massive stars have not yet ejected much of the obscuring dust, the infrared view penetrates the dark lanes of dust, revealing bright swirling clouds and numerous developing stars that have shot out jets of gas (green). This is because infrared light can travel through dust.The infrared image shows light captured by Spitzer's infrared array camera.

I took this before the "Orion's Belt and Sword" one was taken, to make sure the direction is right. The sky was quite clean and Orion is an intrinsically pretty bright constellation, so I only took 16 for stacking and it turned out well.

OK - it's been cloudy, windy, and/or snowy here for the last 3 weeks strait. No chance to get out and take astrophotos so I'm digging through my old stuff for anything amusing. This is a short, 30 second shot of the Orion nebula taken on a windy night 4 or 5 weeks ago. I like it for the dark nebula detail near the trapezium. Often this region gets overexposed and loses detail in the effort to bring out the more faint outer regions of the nebula. So this shot does the opposite. It also demonstrates how bright the nebula is that this amount of light can be captured in just 30 seconds, ISO 400. I intended to get a better shot of this to post but who knows when I'll get that chance??? Here's wishing us all some clear skies!
The Orion Nebula is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. Wikipedia
Messier 42 - The Great Orion Nebula. This was a single 30 sec. exposure using a Nikon D50 camera mounted on a 30" Newtonian F/5 telescope located at the Powell Observatory near Louisburg, KS. By keeping the exposure short, the trapezium (the 4 stars in the center of the bright white region) did not get too washed out. It can be viewed better as a larger image. To view as a larger image click on the image, then the magnifying glass. The region near the bottom of the picture is classified as M43 (Messier 43)
This is the Great Orion Nebula, aka M42. It is the second star in the small 3-star chain that is Orion's sword. You can find it by looking just below his belt.
This shot was taken on February 19, 2012, using my Canon 7D and my 80mm Refractor. It's my first properly exposed and processed astrophoto.
I shot 10x15s @ 800 iso, 11 30s @ 800 iso, and 15 90s @ 800 iso. I did so many different exposures as I was trying to see which combination would look best.
This is a picture of the Pleides, aka M46. This is an open cluster of stars also referred to as the "seven sisters". They are the basis of the Subaru logo, and have been used by ancient armies as an eye examination. Typically it's possible to see up to 6 stars naked eye in the city, if you have good vision.
I shot this using my 80mm refractor and my Canon 7D. I explosed 6x90s @ 1600 ISO, and 5x120s @ 800 ISO
The Hubble Space Telescope continues to reveal various stunning and intricate treasures that reside within the nearby, intense star-forming region known as the Great Nebula in Orion.
As part of the work to reach a stable milestone of AstroTortilla and a fully featured out-of-the-box installation experience, I just had to take a pic of my finder scope wrapped in a tortilla, as that's all it's good for these days. Crops of this now make up the application icons and installer images in the next version of AstroTortilla.
M42/M43 is visible in the background and the melted cheese effect is the result of making a hand-held focus stack with two frames.
Orion Nebula - No telescope
Canon T1i - 300mm F5.6, 6 second exposure ISO6400
6 seconds is too long at this focal length without tracking the sky (the stars are streaked), but i'm surprised it picked up as much of the nebula as it did!

I braved the cold for this one, but I think it turned out pretty solid. I just had to get outside and take a picture of the great orion nebula before I head back to school. Surprisingly, this image contained little noise - probably due to the frosty weather keeping the ccd chilled.

The bright glow at upper left is from M43, a small region being shaped by a massive, young star's ultraviolet light. Astronomers call the region a miniature Orion Nebula because only one star is sculpting the landscape. The Orion Nebula has four such stars. Next to M43 are dense, dark pillars of dust and gas that point toward the Trapezium. These pillars are resisting erosion from the Trapezium's intense ultraviolet light. The glowing region on the right reveals arcs and bubbles formed when stellar winds - streams of charged particles ejected from the Trapezium stars - collide with material. The faint red stars near the bottom are the myriad brown dwarfs that Hubble spied for the first time in the nebula in visible light. Sometimes called "failed stars," brown dwarfs are cool objects that are too small to be ordinary stars because they cannot sustain nuclear fusion in their cores the way our Sun does. The dark red column, below, left, shows an illuminated edge of the cavity wall. The Orion Nebula is 1,500 light-years away, the nearest star-forming region to Earth. Astronomers used 520 Hubble images, taken in five colours, to make this picture. They also added ground-based photos to fill out the nebula. The ACS mosaic covers approximately the apparent angular size of the full moon. The Orion observations were taken between 2004 and 2005.
The Orion nebula, located in the belt of Orion, (M42). Shot with 200mm on a 1,3 crop camera with a total exposure time of 4 minutes and 18 seconds (stacked image containing 258 pictures with 1 second exposuretime each @ ISO3200).
I have tried to filter out the light pollution which is imminent in the middle of the city.
This the first "okay" image with the full spectrum camera mod. I'm still not pleased but I think now it's a matter of the scope......mostly.
A 2-minute exposure using the 28MM ultra wide angle set at f1.7. The telescope's optical tube assembly is the large black "blob" at the bottom of the image.
