In Italy are back this time confused with the surprise news of the extraordinary Italian unknown. We read in the papers of young people who discover new software in a garage and find the funding for this new company in Los Angeles but not in Italy we know of scientists who make medical discoveries from the Nobel Prize in American hospitals. It 's almost a symbol of our Italy without a guide and as a collapsed star, it sends its rays through the universe. Take this picture of a phenomenon that occurs in the Crab Nebula, which is called the diamond crazy and who happens to be the subject of a discovery of Italian astronomers. Can you describe it Mark Tavani Corriere della Sera on January 25, 2011:
"... Two discoveries of satellite Agile 's Italian Space Agency are of great interest. The first concerns one of the most famous nebulae in our galaxy. Agile's first caught a strong emission of gamma radiation from the spectacular Crab Nebula, so far believed to be the source of cosmic X-ray and gamma-stable for excellence. A totally unexpected phenomenon and a kind of "heresy" for astronomers. Confirmation came later by satellite, "Fermi" of NASA. Since then, astronomers look at the 'Crab' to trying to steal the secret of this variable emission lasting a few days before reverting to normal. Researchers' and Inaf 's Infn involved in the two satellites have reported the discovery in the journal Science ... "
The Crab Nebula, and the rapidly rotating neutron star that is feeding, the remains of' a supernova explosion, recorded by astronomers China and the Middle East, in 1054. After missing most of the external gas and dust, the dying star has collapsed under the form of a pulsar, a super dense ball of neutrons, in rapid rotation, which emits pulses of radiation every 33 milliseconds, like a clock.
E 'is great but only about 16 km in diameter, the amount of power that the pulsar is really big issue, so as to shine the entire Crab Nebula up to 75,000 times the Sun's Most of its energy is contained in the particles of wind energy electrons and positrons that travel near the speed of light. These electrons and positrons interact then the magnetic fields and low-energy photons to produce the bright, colorful strands of dust and gas that Messier exchange for a comet about 300 years ago.
The two discovered that our Italian astronomers have called the crazy diamond open the door to a great mystery of the human mind: the famous "where we come from and where are we going?". The great crisis of the world ungovernable globalization brings us back to ancestral fears and concerns. Maya prediction fixes the end of the world to an improbable 2012. We do not believe, but realistically we think that if we do not build a world order, the catastrophe of another war would be far more deadly. Which brings us open these findings? He tells George Smoot Nobel Prize in an interview with Paola Antonini on Il sole 24 ore :
"... Our knowledge is limited to 4% of matter makes up the universe in which we live: that's why the expectations for this mission are important to the entire scientific community. This raises the big questions of cosmology here on age of the Universe, the pace of its expansion, dark matter and dark energy. " is a innate human impulse to explore and learn? "It seems this curiosity to lead to challenges in increasingly audacious - responds Smoot -. So we are studying the structure of the universe and its relationship with humans. Pascal said that man is half way between the infinitely small and the infinitely large: this would seem the only possible position to understand the Universe. " Exploring and learning are synonymous?
'Exploring the Universe is the extreme frontier to reveal new scenarios. Sure, there are also others, like the investigation of mechanisms that regulate the interactions at high energy in infinitesimal steps, but they belong to a wider reality. The aim should be able to study the cosmological models related to the laws of microphysics in the early Universe "..."
But because we are dealing with us? The arc of action of the policy is not perhaps an igloo ice that has no windows on the universe? No, it does not. These pictures belong to us. The crazy diamond, the star explodes, the black hole absorbs a larger mass of the earth in seconds, as he said Leopardi, are the image of our problems.
