Voyager from the edge of the solar system recorded Incredible scenes

Twin NASA mission, Voyager, which is located at the entrance of the galaxy for the first time in history has peered outside the solar system and recorded images of the human eye has never seen.

According to new research, the two aircraft were in other parts of the Milky Way ultraviolet light recorded by our instruments so far from hiding blinding glow of our parent star.

"People were trying to perform these measurements from Earth orbit, but that they never succeeded," said veteran Bill Sandel Voyager missions with the University of Tuscany.

This frequency of light, known as alpha radiation Limanovo, send the hydrogen atoms that are cooled. On Earth, it is almost impossible to detect this radiation, since UV signals in our galaxy are disappearing in a sea of ​​solar radiation scattered stray hydrogen atoms, just as the stars invisible during the day because the atmosphere scatters the sun's rays.

Scientists have already managed to capture Limanovo alpha radiation from distant galaxies, because it comes with a certain shift towards the red end of the spectrum caused by expansion of the universe. This change in frequency of light emission makes it possible to clearly distinguish it from solar. No emission from our galaxy have a redshift, so it is much harder to distinguish.

Voyager 1 and 2 were launched in 1977. year. The 2004th they entered the Solar System and are now about 100, or 120 times the distance from the Sun than Earth.

This distance and the new data analysis techniques have enabled scientists to distinguish between galactic radiation from the Sun. The new data will allow a better understanding of the structure and properties of distant galaxies.
