Telescope "Plank" said the composition and age of the universe

Scientists from the Space Telescope "Plank", failed to make the most accurate map of the "echo" of the Big Bang, and to clarify the age of the universe, "wear" it on tens of millions of years, according to the website of the European Space Agency.

The main task of the European telescope "Plank" (Planck), launched in May 2009, was to scan the entire sky at least twice and get a more complete picture of the so-called "echo" of the Big Bang or the CMB. "Plank" finished the first scanning session in July 2010, and the new data were telescope, according to scientists, the most anticipated event of 2013.

These data, as the ESA, have enabled researchers to clarify the date, the value of the Hubble constant, and the value of the expansion rate of the universe that "Plank" estimated at 67.15 kilometers per second per Mpc. This indicates that the rate of two galaxies are separated one Mpc distance that is approximately 3 millions of light years, is about 67 kilometers per second when they scatter. The corrected value is also allowed scientists to count and the "age" of the universe, now estimated at 13.82 billion years old.

The space telescope has also helped to clarify the "recipe" of the universe. Thus, the share of "normal" matter, according to experts, has 4.9% of its mass, dark matter, detected so far only on circumstantial evidence, which is 26.8% more than previously thought. The rest comes from other, even more mysterious dark energy, which is involved in the process of accelerating expansion of the universe.

The new card, "Plank", according to scientists, in general, very well with the standard cosmological model, the accuracy of the map and enabled to detect a number of anomalies. This includes, in particular, the famous "cold spot", which is an area of abnormally low temperature radiation, which was first discovered by the probe WMAP - the predecessor "Plank". Astronomers stress that spot along with other anomalies now "can not be regarded as artifacts or measurement errors - they are real, and they need to look for an explanation."
