“Voyager 1″ came out a year ago from the heliosphere – the studies have now definitely proved. Since then, the spacecraft flies first manmade object through interstellar space.
Only a few weeks ago had other researchers reported that the earthly messenger was advanced into a previously unknown region on the border of our solar system. Since 1977, when the veteran was launched in space 18 billion kilometers from the Sun. From this distance, the transmitted signals it will need 17 hours until they reach the Earth. For comparison, the distance Earth – Sun is almost 150 million km (this distance, the astronomers use as distance measure, it corresponds to an astronomical unit, shortly AE). Voyager 1 is now at the moment about 124 times farther away.
Astro Physically the heliosphere is seen the influence area of ??our home star. Which line – the so-called Heli – is defined as the point at which the magnetic influence of the sun ends. Where the constant of their emitted particle encounters the interstellar particles flowing from the universe, and the magnetic field of our central star bends. The border region before the heliopaus e in turn is called “Helio vagina.” But the heliosphere is not a sphere, as the name suggests, but they appear deformed, because the solar system is flying rapidly in its orbit through the Milky Way. In the moving direction, it is flattened, elongated on the other side as a wind bag. When the interstellar medium by plow pushes the heliosphere as a moving vessel a kind of bow wave in front of it.
