Voyager One Reached a Surprisingly Quiet Area on The Boundary of Interstellar Space

The most distant object ever created by man, is at a distance of 17.5 billion miles from Earth – at the boundary of interstellar space.
Voyager one approached the boundary of the heliospheric mantle, where the particles emitted by the sun face with galactic gases. Contrary to the expectations of scientists, the border was quiet harbor, where the solar wind mixes with particles from outside the solar system.

The most distant object ever created by man, is at a distance of 17.5 billion miles from Earth – at the boundary of interstellar space.

Voyager 1 approached the boundary of the heliospheric mantle, where the particles emitted by the sun face with galactic gases. Contrary to the expectations of scientists, the border was quiet harbor, where the solar wind mixes with particles from outside the solar system.

“We are still in the transition region, where the influence of the sun is quite noticeable,” – said Stamatios Krimidzhis, a physicist at Johns Hopkins University in Laurel, Maryland. “It’s definitely not what we expected.”

Scientists from NASA cut off six of the ten instruments on board Voyager 1. He went so far as to transfer the data to Earth takes 16 hours. But the work of the Voyager does not stop for a second. He leaves the heliosphere, a bubble which is filled with the solar wind. At the end of 2004, Voyager 1 crossed the shock wave, where there is a sharp slowdown in the solar wind. And this year, researchers expect that it crosses another boundary on which the solar wind abruptly change direction, that would mean out into interstellar space.

But instead, according to Krimidzhisa, measurement of low energy particles showed that the solar wind almost stopped and began to mix with the interstellar gas. Existing theories failed to predict this development. Krimidzhis allows for the possibility that this is interstellar space. “We might have to go into it without even knowing it, because there is no model that would describe what we see,” – he said.

Data on remote interstellar gas may seem irrelevant to humanity, which is located closer to the sun. But, according to Ed Stone of the California Institute of Technology in Pasadena, this information is very important. At the moment, the sun passes through a zone that is saturated with the remains of several nearby supernova. Particle flows and magnetic fields that creates our star, protect us from the interstellar radiation occurring during the explosions. “The size of the bubble is important.”

In the future, Voyager will provide more information on this issue. Plutonium generator must serve at least until the 2020s, and “we will continue to receive information,” – said Krimidzhis. Even when its signal is damped, the journey will not stop … About 40 000 years it will reach the constellation Camelopardalis.
