Mars's dramatic climate variations are driven by the Sun

On Mars's poles there are ice caps of ice and dust layers with that reproduce to past climate variations on Mars. Researchers from the Niels Bohr Institute have related the layers in the ice cap on Mars's north pole to variations in Solar insulation on Mars, the first dated THUS climate Established history for Mars, where ice and dust accumulation has been driven by variations in insulation. The results are published in the scientific journal, Icarus.

The universe still has a lithium problem.

That's the allegation of a paper in this week's Nature by Researchers from the University of Notre Dame and the University of Illinois at Urbana-Champaign. Processes just after the Big Bang created ought To Have Certain Amounts of elements Such as hydrogen, helium, and lithium. Astronomers already knew the universe has far less of the isotope lithium-7 than it Should - studies of the old stars that surround the Milky Way

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.

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.
