NASA discovered a huge shining “hydrogen wall”

NASA обнаружило огромную сияющую «водородную стену»

“The wall” in question is located at the outer edge of our solar system — where the ends of the bubble of solar wind, and the mass of interstellar matter is too small to break through, so she is going around and presses on it.

About it writes the Telegraph.

Powerful emissions of matter and energy from the Sun travels great distances from the star, far beyond the orbit of Pluto. At some point they run out, and with them their ability to repel dust particles and other matter. Formed visible border. On one side of her — the last vestiges of the solar wind. On the other hand, the accumulation of interstellar matter, including hydrogen.

NASA are confident that the New Horizons probe crossed the orbit of Pluto in 2015, will be able to see this border. The researchers wrote in a report published August 7 in the journal Geophysical Research Letters. They claim that the probe will see excess UV light: according to scientists, this radiation will come from the walls of the galactic hydrogen. This signal has registered two devices Voyager in the distant 1992.

However, the researchers noted: the signal does not mean that New Horizons considered for the hydrogen wall, or saw her for the Voyager spacecraft. In fact, all three of the probe was able to register the UV radiation from some other source, which is located much further in the Galaxy.

However Alice instrument aboard New Horizons, which is responsible for this detection is more sensitive than anything aboard the spacecraft Voyager. The researchers also noted that Alice will work another 15-20 years. New Horizons will continue to scan for the presence of ultraviolet radiation twice a year and will send data to the Ground.

“If at any time the UV radiation will be gone, so New Horizons left the wall in the rearview mirror, the researchers explain. But if the radiation is not lost, therefore, its source is much farther away — somewhere in outer space”.

Previously, NASA was unable to launch sun probe Parker worth $ 1.5 billion.
