PIX4621115: Star Formation in the DR21 Region - Star Formation in the DR21 Region - This star formation region is about 6200 years old - light. Hidden in light visible by interstellar dust, this region rises in infrared light. Gas filaments appear in red; they emphasize the presence of aromatic polycyclic hydrocarbons (PAH); they are organic molecules composed of carbon atoms and hydrogen that could be the germs on which the first bricks of life appeared. Composite image in different wavelengths obtained by the Spitzer space telescope; in blue the visible light, in yellow and red the infrared light. Hidden behind a shroud of dust in the constellation Cygnus is a stellar nursery called DR21, which is giving birth to some of the most massive stars in our galaxy. Visible light images reveal no trace of this interstellar cauldron because of heavy dust obscuration. This image from Nasa's Spitzer Space Telescope allow us to peek behind the cosmic veil and pinpoint one of the most massive natal stars yet seen in our Milky Way galaxy. The never - before - seen star is 100,000 times as bright as the Sun. Also revealed for the first time is a powerful outflow of hot gas emanating from this star and bursting through a giant molecular cloud. This colorful image is a large - scale composite mosaic assembled from data collected at a variety of different wavelengths. Views at visible wavelengths appear blue, near - infrared light is depicted as green, and mid - infrared data is portrayed as red. The result is a contrast between structures seen in visible light (blue) and those observed in the infrared (yellow and red). The image covers an area about two times that of a full moon. The red filaments stretching across the Spitzer image denote the presence of polycyclic aromatic hydrocarbons. These organic molecules, comprised of carbon and hydrogen, are excited by surrounding i / Bridgeman Images
PIX4621162: Dark nebula and globular cluster NGC 4372 - Dark nebula and globular cluster NGC 4372 - HMSTG 436 is a molecular cloud visible near the globular cluster NGC 4372 (on the right, above the bright star Gamma Musca) in the southern constellation of the Fly. HMSTG 436 is a linear molecular cloud in the southern constellation Musca, the fly. It is easily found by targeting the globular cluster NGC 4372, visible at right, above the bright star gamma Musca / Bridgeman Images
PIX4621239: Nebulae B175 and VDB 152 in Cephee - Dark nebula B175 and reflection nebula VDB 152 - In the center of the image, a large dust trail leads to a blue nebula. This is the dark nebula, Barnard 175, which coaches the nebula by reflexion VDB 152 (Ced 201). In the center of the image a large dust band, B175; above is the reflection nebula VDB 152 (or Ced 201). These objects are located in Cepheus constellation / Bridgeman Images
PIX4621533: The Rho Ophiuchi nebula seen in infrared - Rho Ophiuchi in infrared - This coloree nebula represents part of a very vast molecular cloud, the Ophiuchus cloud. This star-forming region is about 520 years old - light. The triple star Rho Ophiuchus is located in the top center of the image. Below, a very bright nebula is visible, accompanied by a group of very young stars. At the bottom right, surrounded by a reddish nebula, the star Sigma Scorpii. The globular clusters NGC 6144 (bottom, center of the image) and M80 (top right of the image) are also visible on this infrared image obtained from the Wide - field Infrared Explorer (WISE) satellite. A rich collection of colorful astronomical objects is revealed in this picturesque image of the Rho Ophiuchi cloud complex from Nasa's Wide - field Infrared Explorer, or WISE. The Rho Ophiuchi cloud (pronounced 'oh - fee - yoo - ki' and named after a bright star in the region) is found rising above the plane of the Milky Way in the night sky, bordering the constellations Ophiuchus and Scorpius. It's one of the nearest star - forming regions to Earth, allowing us to resolve much more detail than in more distant similar regions, like the Orion nebula. The amazing variety of colors seen in this image represents different wavelengths of infrared light. The bright white nebula in the center of the image is glowing due to heating from nearby stars, resulting in what is called an emission nebula. The same is true for most of the multi - hued gas prevalent throughout the entire image, including the bluish, bow - shaped feature near the bottom right. The bright red area in the bottom right is light from the star in the center - - Sigma Scorpii - - that is reflected off of the dust surrounding it, creating what is called a reflection nebula. And the much darker areas scattered throughout the image are pockets of cool, dense gas that block out the background light, resulting in / Bridgeman Images

In a Moorish Hispano style, with predominance of Maghreb influences for interior decoration and emerald tiles reminiscent of the Alhambra (Spain). / Bridgeman Images
PIX4622995: Planetary nebula NGC 2899 dans les Voiles - A distorted planetary nebula, NGC 2899 - This nebula is located about 3000 years from Earth. Image obtained by the 3.9m telescope of Siding Spring Planetary nebulae present a wide variety of forms on the sky, partly because of the random orientation of their parent stars but also because the nebulae themselves can have quite different intrinsic shapes. Theories about the shapes of planetaries range from the influence of binary companions to the central star to the distribution of material around the stars during its red giant phase, before the final outburst. Whatever the mechanism, most planetaries are symmetrical about one or more axes and only rarely do they appear curved like NGC 2899. A possible explanation is that the star from which the nebula was ejected had a large proper motion through space. The resulting nebula has the same velocity but vastly lower density than the star so is distorted by its encounter with the tenuous interstellar medium. Distance to planetary nebulae are usually uncertain, but in this case it seems to be about 3000 light years / Bridgeman Images
PIX4622743: Cocoon Nebula (IC 5146) in Swan - Cocoon Nebula - IC 5146 - in Cygnus - The Cocon Nebula, IC 5146, is an emission nebula located about 4000 years from Earth in the constellation of Swan. This complex mass of molecular hydrogen and dust, located 4,000 light years from earth, glows red by emitting light, shines blue by reflecting light and exhibits a pattern of dark lanes that result when dust absorbs light. Much of the light seen in the main part of this nebula is generated by the massive bright star near it's center. The Cocoon is a stellar nursery containing a relatively young open cluster of stars with several individual constituents that are newly formed. Wide angle, long exposure photographs reveals the nebula to be very extensive - essentially a vast river of interstellar dust / Bridgeman Images
