Redshift-PIA02038.jpgIn the midst of Time...57 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.

NGC-4038_and_NGC-4039-3.jpgNGC 4038 and 4039: The "Antennae" Colliding Galaxies57 visite"...Ambition is the last resort of failure..."
(Oscar Wilde)
Caption NASA originale:"Some 60 million LY away in the southerly constellation Corvus, two large galaxies have collided. But stars in the two galaxies - NGC 4038 and NGC 4039 - don't collide in the course of the ponderous, billion year or so long event. Instead, their large clouds of molecular gas and dust do, triggering furious episodes of star formation.
Spanning about 500.000 LY, this stunning view reveals new star clusters and matter flung far from the scene of the accident by gravitational tidal forces. Of course, the visual appearance of the far-flung arcing structures gives the galaxy pair their popular name - "The Antennae". Recorded in this deep image of the region at the tip of the upper arc is a tidal dwarf galaxy NGC 4038S, formed in the cosmic debris".
