The heliosphere, a cosmic bubble formed by the Sun, protects our solar system from interstellar threats and influences life's ...

Together they form the heliosphere within the surrounding local interstellar medium – the plasma, neutral particles and dust that fill the space between stars and their respective astrospheres.

Both probes are the only spacecraft to operate beyond the heliosphere ... and interstellar plasma, interstellar magnetic fields and radio waves in the interstellar medium, including any effects ...

We can probe the ionized interstellar medium through imaging and timing observations of compact radio sources. As the radio waves pass through the interstellar medium, they are distorted and delayed ...

This journey through a dense region of space could have compressed the heliosphere, the protective bubble surrounding our solar system, and increased the influx of interstellar dust, potentially ...

But that's not all it does, and it affects a much larger area of space. The heliosphere, the area of space influenced by the sun, is over a hundred times ...

To save energy for further interstellar exploration ... Voyager science team's determination that Voyager 1 had exited the heliosphere, the sun's sphere of influence at the edge of the solar ...
