PIX4620190: The Omega nebula (M17) seen in infrared - M17 nebula in infrared - The Omega nebula (M17) seen in infrared by the Spitzer space telescope. M17 is a star-forming region about 6000 light years ago in the constellation Sagittarius. In the center of the nebula is a group of massive stars. The dust appears in red, the hot gas in green, the regions or this gas and the dust mixes in white. Nasa's Spitzer Space Telescope has captured an infrared view of the star - making cloud called M17, or the Swan nebula. 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. 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. Three of these bow shocks are nestled in the upper left side of the central cavity, but are difficult to spot in this view. 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 / Bridgeman Images

PIX4621152: Star Formation in Cassiopee - Star Formation in Cassiopeia - This star-forming region, called W5, is located approximately 6500 light years ago in the constellation Cassiopee. Several generations of stars appear on this cliche; the older ones are the blue stars in the centre of the two cavities; the younger stars are grouped at the edges of these cavities and at the ends of the gas pillars or they appear like pink dots; the white areas are home to the very young stars in formation. In this infrared image, heated dust appears in red, dense gas clouds appear in green. Composite image obtained by the Spitzer space telescope in 2006 and 2007. Generations of stars can be seen in this infrared portrait from Nasa's Spitzer Space Telescope. In this wispy star - forming region, called W5, the oldest stars can be seen as blue dots in the centers of the two hollow cavities (other blue dots are background and foreground stars not associated with the region). Younger stars line the rims of the cavities, and some can be seen as pink dots at the tips of the elephant - trunk - like pillars. The white knotty areas are where the youngest stars are forming. Red shows heated dust that pervades the region's cavities, while green highlights dense clouds. W5 spans an area of sky equivalent to four full moons and is about 6,500 light - years away in the constellation Cassiopeia. The Spitzer picture was taken over a period of 24 hours. Like other massive star - forming regions, such as Orion and Carina, W5 contains large cavities that were carved out by radiation and winds from the region's most massive stars. According to the theory of triggered star - formation, the carving out of these cavities pushes gas together, causing it to ignite into successive generations of new stars. This image contains some of the best evidence yet for the triggered star - formation theory. Scientists analyzing the photo have been able to sho / Bridgeman Images
