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.

The interaction of the heliosphere with the local interstellar medium—a material made of plasma, dust, and neutral particles filling the space between astrospheres—forms the shape of our ...

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 ...

NASA is considering a new interstellar probe to study the heliosphere from the outside, providing unprecedented data on its structure and interactions. The heliosphere blocks cosmic rays ...

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 ...

The heliopause is where the solar wind bumps up against the pressure of interstellar space. Everything on our side of the heliopause is the heliosphere. It’s like a giant bubble around our star.

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 ...

Both probes are the only spacecraft to operate beyond the heliosphere, the sun’s bubble of magnetic fields ... information on particles such as energetic cosmic rays and interstellar plasma, ...

In 2018, Voyager 2 crossed the heliosphere’s boundary, officially entering interstellar space and transmitting data from beyond the Sun’s influence. Despite the shutdowns, Voyager 2 continues ...
