Cambridge, MA - The
Sloan Digital Sky Survey III (SDSS-III) has released the largest
three-dimensional map of massive galaxies and distant black holes ever created.
The new map pinpoints the locations and distances of over a million galaxies.
It covers a full volume equivalent to that of a cube four billion light-years
on a side.

Hill, one of the most famous craters of the moon can be 5 to 10% water ice
The new approximation
of the amount of water ice led to radar Mini-RF, on board the American
"moon" of the probe LRO. The focus, as in many similar studies,
focused on the Moon's south pole, where the deep crater Shackleton . These
places are the most promising for the construction of this permanent manned
base on the edge of the crater found a lovely flat landing area, and located
very near to the "peak of eternal light", where the sun shines
constantly, it would be convenient to install solar panels.
Sweet space: sugar from STAR
In a cloud of
gas and dust around young stars are found far monosaccharides. The simplest the
"building blocks of life" - exactly the right time and the right
place to be on the planet-forming.
Binary star IRAS
16293-2422 is not so far, only 400 light-years from Earth in the gas and dust
cloud surrounding the Rho Ophiuchi. Her entourage Danish astronomer Jess
Jorgensen (Jes Jorgensen) and colleagues observed in the infrared, with the
observatory ALMA , revealed traces glikolaldegida .

Discovered another planet, which can have a life,
Gliese 163 c is
classified as “sverhzemel "stone the size of the planets in our not too
big: it is estimated minimum mass of 6.9 Earth. It rotate around a red dwarf star,
making a complete rotation every 26 Earth days. Distance away from the star is
about 50 light-years away in the direction of the southern constellation
Dorado.
A star cluster has a secret
The ESO La Silla
Observatory in Chile shows the stunning globular star cluster Messier 4. This
group consists of tens of thousands of antique stars is one of the closest and
one of the most studied globular clusters. Recent research has exposed that one
of its stars has unusual and surprising properties; apparently it is the secret
of eternal youth.
Seeing the Birth of the Universe in an Atom of Hydrogen
Stars can unveil
the history of our universe, Currently Estimated to be 14 billion years old.
The beyond away the star, the older it is - and the oldest stars are the most difficult
to detect. Current telescopes can only see galaxies About 700 million years
old, and Only When the galaxy is unusually large or as the result of a big
event like a stellar explosion.
Now, an international
team of scientists led by researchers at Tel Aviv University have developed a
method for detecting galaxies of stars That Formed When the universe was in its
infancy,

Multi-tasking Supernova: stellar explosion galaxy far-off
Nature hath no fury
like a dying star - and astronomers could not be happier...
An international
research team, led by Edo Berger of Harvard University, made the most of a
dying star's passion to probe a distant galaxy some 9.5 billion light-years
distant. The dying star, which lit the galactic scene, is the MOST distant
stellar explosion of its kind ever Studied. According To Berger, "It's
like someone turned on a flashlight in a dark room and allowed us to see suddenly,
for a short time, what this far-off galaxy looks like, what it is composed
of."
