When these fast particles are carried through the atmosphere, there are faint flash of blue light. Stereoscopic system for the registration of high-energy (HESS), representing a group of telescopes located in Namibia, has documented these outbreaks, the source of which was pks 2155-304. Gamma rays with low energies directly detected wide telescope (Large Area Telescope – LAT), installed aboard the orbiting gamma – Fermi Telescope, nasa. 'Run Fermi Telescope (Fermi) gives us opportunity to spend the first measurements of this powerful galaxy from edge to edge in different wavelength ranges ", – said Werner Hofmann (Werner Hofmann), the group's spokesman hess at the Institute of Nuclear Physics. Max-Planck-Heidelberg (Heidelberg), Germany. Since the observation of gamma radiation has been completely secured, the group turned to space satellites with X-ray telescopes, Swift (Swift) and Rossi (Rossi) X-ray Timing Explorer (RXTE), nasa, to provide X-ray data emission of the galaxy. Completed the study robotic telescopes monitor the optical range hess, who recorded the activity of the galaxies in the visible spectrum. In the period between August 25 and September 6, 2008 telescopes monitored pks 2155-304, when the galaxy is at rest, in the absence of bright flashes.

Results of observations of the 12-day campaign were awesome. In times of outbreaks of this and other blazars and wavelets and downs of X-ray and gamma-ray emission occurs at a time. But this timing was not observed during periods when the object pks 2155-304 was in a quiescent state, and nobody knows why. What was even more strange is the fact that the increase and decrease the emission of the galaxy in the visible spectrum occur synchronously with bursts and busts of gamma radiation. 'This is similar to the behavior of solder burner: when the maximum and minimum temperature change synchronously, and the average temperature – no, – said Berry Gibels (Berrie Giebels), an astrophysicist at the Polytechnic Institute in France, which works with both groups – the leading observations with hess and Wide teleskopFermi (Fermi LAT). 'Astronomers have come to the conclusion that the various components of the jets in blazar interact rather complex way, creating the emission that we observe', – says member of the group research using a telescope Fermi (Fermi) Jim Chieng (Jim Chiang) from Stanford University, California. "These observations may contain the first clues of what is actually happening in the Blazar heart. "

Imperial Palace

Here we set the ice sculptures and compositions from the snow. In his time at the park you could see Buckingham Palace (12 meters in height), Taj Mahal Palace and the main Okinawan Shuri Castle Complex. The capital of Tokyo – the most visited tourist city in Japan. Must see the Imperial Palace (formerly Edo Castle), the temple Tosegu, the Tokyo television tower (height – 333 meters) skyscraper Sunshine City, old parks – Rikushen, with regular exhibitions chrysanthemum, known for its pagodas and temples Shiba Park. In the city of more than 30 museums, the most interesting of them – The National Science Museum in Ueno Park, the Historical Museum , Tokyo National Museum, National Museum Modern Art Museum of Kite, the Tokyo Metropolitan Museum of Art, the Museum of Idemitsu with a collection of paintings and calligraphy. Pride of Tokyo – Disneyland, created in the image of California.

It opened in 1983 and the number of rides and brightness now surpasses its American counterpart. In 2002, close to Disneyland opened Disney Sea, on marine topics Walt Disney cartoons. Hakone – a popular resort on the island Honshu, which is famous for its hot springs (onsen) and the extraordinary charm. In a number of hotels in Hakone arranged entire cascades rotenburo – bathing in the open air, lying in which one can simultaneously enjoy the magnificent views of mountains and valleys. Fuji – a symbol of Japan. This is one of the most beautiful sleeping volcanoes in the world.
