Amazing Pictures in Space

   This image provided by NASA Tuesday Nov. 11, 2009 shows observations from the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory in a collaboration to produce an unprecedented image of the central region of our Milky Way galaxy using infrared light and X-ray light to see through the obscuring dust and reveal the intense activity near the galactic core. Note that the center of the galaxy is located within the bright white region to the right of and just below the middle of the image. The entire image width covers about one-half a degree, about the same angular width as the full moon. Each telescope's contribution is presented in a different color. Yellow represents the near-infrared observations of Hubble. The observations outline the energetic regions where stars are being born as well as reveal hundreds of thousands of stars. Red represents the infrared observations of Spitzer. The radiation and winds from stars create glowing dust clouds that exhibit complex structures from compact, spherical globules to long, stringy filaments. Blue and violet represent the X-ray observations of Chandra. X-rays are emitted by gas heated to millions of degrees by stellar explosions and by outflows from the supermassive black hole in the galaxy's center. The bright blue blob on the left side is emission from a double star system containing either a neutron star or a black hole. When these views are brought together, this composite image provides one of the most detailed views ever of our galaxy's mysterious core.This image provided by NASA's Hubble Space Telescope Tuesday Dec. 15, 2009 shows hundreds of brilliant blue stars wreathed by warm, glowing clouds. The festive portrait is the most detailed view of the largest stellar nursery in our local galactic neighborhood. The massive, young stellar grouping, called R136, is only a few million years old and resides in the 30 Doradus Nebula, a turbulent star-birth region in the Large Magellanic Cloud (LMC), a satellite galaxy of our Milky Way. There is no known star-forming region in our galaxy as large or as prolific as 30 Doradus.
An infrared portrait of the Small Magellanic Cloud, taken by NASA's Spitzer Space Telescope, is shown in this handout photo released to Reuters January 5, 2010. The image shows both old stars (in blue) and young stars lighting up their natal dust (green/red). In addition, the image contains a galactic globular cluster in the lower left (blue cluster of stars) and emission from dust in our own galaxy (green in the upper right and lower right corners).
This image taken by the Hubble Space Telescope and provided by NASA shows a close-up of an area in the northwest region of the large Iris Nebula seems to be clogged with cosmic dust. With bright light from the nearby star HD 200775 illuminating it from above, the dust resembles thick mounds of billowing cotton. It is actually made up of tiny particles of solid matter, with sizes from ten to a hundred times smaller than those of the dust grains we find at home. Both background and foreground stars are dotted throughout the image. Researchers studying the object are particularly interested in the region to the left and slightly above center in the image, where dusty filaments appear redder than is expected.

NASA's Spitzer Space Telescope has imaged a coiled galaxy with an eye-like object at its center, shown in this photograph released by NASA July 23, 2009. The galaxy, called NGC 1097, is located 50 million light-years away. It is spiral-shaped like our Milky Way, with long, spindly arms of stars. The "eye" at the center of the galaxy is actually a monstrous black hole surrounded by a ring of stars. In this color-coded infrared view from Spitzer, the area around the invisible black hole is blue and the ring of stars, white.

On April 1-2, the Hubble Space Telescope photographed a group of galaxies called Arp 274. Arp 274, also known as NGC 5679, is a system of three galaxies that appear to be partially overlapping in the image, although they may be at somewhat different distances. The spiral shapes of two of these galaxies appear mostly intact. The third galaxy, to the far left, is more compact, but shows evidence of star formation. Two of the three galaxies are forming new stars at a high rate. This is evident in the bright blue knots of star formation that are strung along the arms of the galaxy on the right and along the small galaxy on the left. The entire system resides at about 400 million light-years away from Earth in the constellation Virgo.
This photo, supplied by NASA-ESA, is a new Hubble Space Telescope image of three galaxies locked in a gravitational tug-of-war that may result in the eventual demise of one of them. The three pictured galaxies -- NGC 7173, middle left, NCG 7174,middle right, and NGC 7176, lower right,-- are part of the Hickson Compact Group 90, named after astronomer Paul Hickson, who first catalogued these small clusters of galaxies in the 1980s. NGC 7173 and NGC 7176 appear to be smooth, normal elliptical galaxies without much gas and dust. In stark contrast, NGC 7174 is a mangled spiral galaxy, barely clinging to independent existence as it is ripped apart by its close neighbors. The strong tidal interaction surging through the galaxies has dragged a significant number of stars away from their home galaxies. These stars are now spread out, forming a tenuous luminous component in the galaxy group.
This undated handout image provided by NASA, released Wednesday, Sept. 9, 2009, taken by the refurbished Hubble Space Telescope, shows a clash among members of a famous galaxy quintet revealing an assortment of stars across a wide color range, from young, blue stars to aging, red stars.
This image provided by NASA Tuesday April 21, 2009 shows a peculiar system of galaxies known as Arp 194. This interacting group contains several galaxies, along with a "cosmic fountain" of stars, gas, and dust that stretches over 100,000 light-years. The most striking feature of this galaxy troupe is the impressive blue stream of material extending from the northern component. This "fountain" contains complexes of super star clusters, each one of which may contain dozens of individual young star clusters. The blue color is produced by the hot, massive stars which dominate the light in each cluster. Overall, the "fountain" contains many millions of stars. This picture was issued to celebrate the 19th anniversary of the launch of the Hubble Space Telescope aboard the space shuttle Discovery in 1990. During the past 19 years Hubble has made more than 880,000 observations and snapped over 570,000 images of 29,000 celestial objects. The Space Shuttle Discovery placed the Hubble Space Telescope into Earth orbit on April 25, 1990.
A meteor streaks past stars in the night sky at the Mont-Tendre near Montricher in the Jura, north of Geneva, late August 12, 2009. The Perseid meteor shower is sparked every August when the Earth passes through a stream of space debris left by Comet Swift-Tuttle.
