For those who yet don’t know, we report that the biggest structure in the universe is a Big Group of Quasars (Large Quasar Group/LQG). This group represents the large-scale structure of the Universe consisting of set of quasars, being in limits of one galactic thread. Unlike rather close super congestions of galaxies, big groups of quasars are extremely far and, probably, are predecessors of modern super congestions and great walls. The first similar group was open in 1982 and it consisted of five quasars. In total such groups at present is known twenty, the biggest structure in the universe consists of 78 quasars. This group was open for the last in 2012. According to scientists even if such structure will travel on the Universe with velocity of light, it needs at least 4 billion years to cross the Universe.
The professor of University of Washington John Kramer recreated the fluctuation of substance on the basis of the relic microwave radiation in the early Universe and turned them into sounds.
As basic data Kramer used results of measurement of the microwave radiation, received recently from the Planck telescope. They reflect temperature fluctuations in the Big Bang, which can be a print of fluctuation of substance. By the words of physicist the initial waves were not variations of temperatures, but the real echo waves, which extended on the Universe.
The scientist transformed data of microwave radiation by the Mathematic program to fluctuations. That echoes became available to the human ear, the received fluctuations should be accelerated very strongly – in 1026 of times. On records gradual strengthening of low tones is audible. According to Kramer, it reflects expansion of the Universe stretching waves of fluctuations.
Results of work of the physicist reflect fluctuations, which happened in the Big Bang when its age made from only 380 to 760 thousand years. Now this age makes 13,4 billion years.
It is very difficult to catch a form of each separate lightning for a short period during the observation of lightning in the sky. But if to direct 15 000 volts on a leaf of multilayered plywood, it is possible to observe the “formation” in details. The student of New York Pratt Institute Melanie Hoff recorded a video, which allows to observe the formation of difficult structures and figures of Likhtenberg. The figures of Likhtenberg are known for a long time, they represent models of distribution of spark channels which are formed on the dielectric surface. For the first time supervision over distribution of spark channels was observed scientific by G.K.Likhtenberg in 1777 in honor of which this phenomenon and received his name.
NASA believes it’s spotted the dappled light of the first objects in the universe with the best precision yet. Using the Spitzer Space Telescope, scientists have observed a lumpy infrared glow that could be coming from wildly massive stars or voracious black holes. The observations help confirm the first objects were numerous in quantity and furiously burned cosmic fuel. As said Alexander Kashlinsky of NASA’s Goddard Space Flight Center these objects would have been tremendously bright.
Astronomers have found the faintest galaxy yet seen in the deep, distant reaches of space, an object whose light has taken 13 billion years to reach us. The tiny galaxy, which existed about 800 million years after the Big Bang created the universe, is among the top 10 most distant objects known. According to astronomers this image is like a baby picture of this galaxy, taken when the universe was only 5 percent of its current age.
The Herschel Space Observatory has discovered a giant, galaxy-packed filament ablaze with billions of new stars. The filament connects two clusters of galaxies that, along with a third cluster, will smash together and give rise to one of the largest galaxy superclusters in the universe. Herschel is a European Space Agency mission with important NASA contributions. The filament is the first structure of its kind spied in a critical era of cosmic buildup when colossal collections of galaxies called superclusters began to take shape.
The Herschel Space Observatory has shown galaxies with the most powerful, active black holes at their cores produce fewer stars than galaxies with less active black holes. The results are the first to demonstrate black holes suppressed galactic star formation when the universe was less than half its current age. Herschel is a European Space Agency-led mission with important NASA contributions. Supermassive black holes, weighing as much as millions of suns, are believed to reside in the hearts of all large galaxies.
According to astronomers at the University of Bonn in Germany, who made the discovery, the structure of satellite galaxies and star clusters around the Milky Way is so vast that it reaches across a million light-years 10 times as wide as the Milky Way itself. Existing dark matter theories fail to explain the arrangement of these cosmic objects. As said study team member Pavel Kroupa, a professor of astronomy at the University of Bon their model appears to rule out the presence of dark matter in the universe, threatening a central pillar of current cosmological theory.
Astronomers by using images from NASA’s Wide-field Infrared Survey Explorer (WISE) reveal an old star in the throes of a fiery outburst, spraying the cosmos with dust. The findings offer a rare, real-time look at the process by which stars like our sun seed the universe with building blocks for other stars, planets and even life. The star, catalogued as WISE J180956.27-330500.2, was discovered in images taken during the WISE survey in 2010, the most detailed infrared survey to date of the entire celestial sky.
