Redshift-PIA02038.jpgIn the midst of Time...55 visiteLike great friends, galaxies stick together. Astronomers using NASA's SST have spotted a handful of great galactic "pals" bonding back when the universe was a mere 4,6 BY old (note: the universe is believed to be 13,7 BY old!).
Collectively, these great galactic buddies are called "Galaxy Clusters".
A typical galaxy cluster can contain hundreds of galaxies and trillions of stars. In this false-color composite, some of the oldest galaxy clusters in the universe pose for SST's infrared array camera. The individual galaxies that make up the distant clusters are shown as red dots in all images.
The green blobs are Milky Way stars along the line of sight, and the blue specks are faint galaxies at various distances along the line of sight. The green and blue data are from a visible-light, ground-based telescope.
The cluster at 9,1 BLY away (lower right panel) is currently the most distant galaxy cluster ever detected.
These images are three-color composites, in which blue represents visible light with a wavelength of 0.4 microns, and green indicates visible light of 0.8 microns. The visible data were captured by the ground-based Mosaic I camera at the Kitt Peak National Observatory in Tucson, Ariz. Red represents infrared light of 4.5 microns, captured by Spitzer's infrared array camera.

Still hesitating,
Any Dream will do..."

Rigel-PIA08187.jpgRising Rigel, from Cassini58 visiteCaption NASA originale:"The brilliant supergiant star, Rigel, emerges from behind the haze of Saturn's upper atmosphere in this Cassini view.
Rigel in is one of the 10 brightest stars in Earth's sky and forms the left foot (sometimes referred to as the left knee) of the familiar constellation Orion.
Imaging scientists use views like these to probe the vertical structure of haze in Saturn's upper atmosphere. The dimming of the star at each altitude in the atmosphere yields information on the density of the haze at that location.
The image was taken in visible green light with the Cassini spacecraft narrow-angle camera on April 28, 2006 at a distance of approx. 663.000 Km (about 412.000 miles) from Saturn. Image scale is roughly 4 Km (such as about 2 miles) per pixel".
