Astronomers Release the Largest Ever Three-Dimensional Map of the Sky

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.
