PIX4621130: Star Formation in the DR21 Region - Star Formation in the DR21 Region - This star-forming 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. Image obtained by the Spitzer space telescope in 2003. 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. The image is a large - scale mosaic assembled from individual photographs obtained with the Infraared Array Camera (IRAC) aboard Spitzer. The image covers an area about two times that of a full moon. The mosaic is a composite of images obtained at mid - infrared wavelengths of 3.6 microns (blue), 4.5 microns (green), 5.8 microns (orange) and 8 microns (red). The brightest infrared cloud near the top center corresponds to DR21, which presumably contains a cluster of newly forming stars at a distance of 10,000 light - years. Protruding out from DR21 toward the bottom left of the image is a gaseous outflow (green), containing both carbon monoxide and molecular hydrogen.

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
PIX4621390: Around the Baade window - The Baade's window region - The Baade Window (at the bottom right of the Gamma star of Sagittarius, the brightest of this image) is a region of the Lactee Way in the constellation of Sagittarius containing little interstellar dust. This region, named in reference to the astronomer Walter Baade, allows astronomers to have a more degagee view of the center of our galaxy. The Baade window, (at the bottom right of the bright star close to the center of this image), is a region of the Milky Way, in the Sagittarius constellation, with relatively little interstellar dust along our line of sight. It is therefore really a unique 'window' through which the astronomers can observe the Milky Way galactic Bulge, only a few degrees from the galactic center. The 'line of sight' through this 'window' passes 1800 light year nearby the Milky Way heart. This region of the sky was named after German astronomer Walter Baade / Bridgeman Images
PIX4621422: Nebulae LBN 552 and Cohen 129 - Nebulae LBN 552 and Cohen 129 in Cepheus - Nebulae in the constellation Cephee. This region in Cepheus does offer delicate reflection nebulae that have been cataloged by Beverly T. Lynds, University of Arizona, in 1965. This catalog was made from studying the red and blue plates taken by the 48 - inch Palomar Sky Survey. Cohen 129 is the small yellow nebula just slightly up of center / Bridgeman Images
PIX4621177: Taurus Molecular Cloud - Taurus Molecular Cloud - This region is located on the border of the Taurus and Persee constellations. Covering about 20 x 30 degres, this image shows a complex of emitted nebulae, star clusters, reflexion nebulae and dark nebulae. A molecular cloud is a region of dense gas and dust composed mainly of molecular hydrogen and helium. It's a birthplace of stars. The Molecular Cloud of Taurus is located about 400 years ago - light, and is one of the closest molecular clouds to our solar system. The California Nebula (NGC 1499), an emission nebula located about 1000 years ago - is visible at the top right. The dark nebulae B7, B18 and B19 are visible near the center of the image. Les Pleiades, M45, is the open cluster at the bottom right center. The open clusters NGC 1817, NGC 1746, NGC 1647 are on the left side of the image. The Hyades, Melotte 25, is a V-shaped cluster at the bottom left. It is the closest open cluster, located at a distance of about 151 light years. Aldebaran, Alpha Tauri, a bright red star with a magnitude of 0.75 to 0.95, is located at one end of the V, but does not belong to the cluster. The Taurus Molecular Cloud (TMC) is located on the border of the constellations of Taurus and Perseus. It is a large dense area of gas and dust in space made mostly of molecular hydrogen and helium. It is a birth place of stars, which form from the material in the cloud. Covering about 20 x 30 degrees, this wide - angle image shows a complex of bright red emission nebulae, star clusters, blue reflection nebulosity, and complex dark nebulae. The TMC is located about 400 light years away, and is one of the closest molecular clouds to our solar system. The California Nebula (NGC 1499), a very large red emission nebula, is at upper right. Emission nebulae are made up of glowing hydrogen gas. Located in / Bridgeman Images

MDA4648118: Shellhaus, Tiergarten to Berlin (Germany). Before he could build this office building, which had the revolutionary look of the period, the architect Emil Fahrenkamp had to review his plans almost three hundred times before the town planning commission gave its approval in 1930. In 1931, Shell House was inaugurated. Its undulating facade in decrochees was born thanks to the use of a metal frame, a first in Berlin. The dynamic wing, visible to the Landwehrkanus, has a height of five levels in its lower part, gradually reaching ten. Damaged during World War II, the Shell House underwent successive restoration work, respecting its historical aspect and the original interior fittings. In 1965-1968, two towers designed by Paul Baumgarten were added to him on his North wing. The final work took place from 1997 to 1999, and enabled the Berlin gas company, GASAG, to set up its headquarters there., Denance, Michel / Bridgeman Images
