X-ray of the Universe

In 2014, the orbit is scheduled to be scientific apparatus "Spectrum X-Gamma." Its main mission — to create a map of the universe. It will mark all the major clusters of galaxies. Large-scale maps of the universe — like time travel. One of the main questions that should be answered "Spektr-RG" — took place as the evolution of galaxies. The satellite is being built in NPO. Lavochkin, a research program developed at the Institute of Space Research.

A computer model of our solar system from a distance of several light years. As the distance of objects in the picture more. This is a distance of two billion light-years — a lot of galaxies.

"The nodules on the map are called galaxy clusters. Smaller nodules are called groups," — said a senior researcher at the ISR Burenin Rodion.

Look around the Universe Astrophysics dream for half a century. First map of our universe were limited accumulation of several thousand galaxies. A recent review by Sloan, named after the founder of the Alfred P. Sloan Foundation project — already millions of galaxies and the scale — four billion light years away.

"Sloan survey data help to see the distribution of matter in the universe and see the baryon acoustic oscillations, which we called the Sakharov in Russia. They are for short talk, echoing the big bang," — says Rodion Burenin.

In 2014, the orbit will withdraw Russian spacecraft "Spectrum X-Gamma." His mission — a real universal census. Map with even greater scale equal to the age of the universe.

"In fact, we find all clusters are formed in the universe," — says the Deputy Director of the Institute for Space Studies Michael Pavlinsky.

One of the main issues to resolve "Spektr-RG", the evolution of galaxies. Why in the center of each galaxy massive black holes, and how eventually changed their weight. The only thing that still remains a dream of the future, look beyond the boundaries of the universe.

"The observable part of the universe is finite, when we look very far, we come to the time when the universe was very dense, it's called the big bang and the light could no longer apply directly," — says Rodion Burenin.

Testing of the unit will be completed soon. Engineers started building summer version. Construction — two X-ray telescope: the Russian and German.

"This is the largest in the history of cooperation between Russia and Germany in the field of scientific experiment space. Telescopes will work in different bands. Unique combination when they complement each other," — Deputy Director of the Institute for Space Studies Michael Pavlinsky.

Orbit "Spectrum RG" — half a million kilometers from Earth, four times farther than the moon. The so-called libration point or Lagrange point. The workplace of many space observatories. There is an atmosphere of our planet does not interfere, and the attraction of the Earth and the Sun balance the machine, adjust the orbit is not necessary.

"There are conditions abstain from befogging, continuous radio-visibility conditions, maintenance of energy balance," — said the head of the project "Spektr-RG" Vladimir Babyshkina.

Today is already working on the orbit space telescope "Radioastron" scanning the universe at radio frequencies. Following the "Spektr-RG" sent into space orbiting observatory "Spectrum-UV" for deep space exploration in the ultraviolet. Mysteries of the universe will be less.
