Astronomers have described the first measurements of plasma layers within an interstellar shock wave that surrounds a pulsar.

In our neighborhood of the Milky Way, we see a region surrounding the solar system that is far less dense than average. But ...

The scintillation arcs also gave us the velocities of the plasma layers. Far from being as expected, we discovered that one ...

The spacecraft is being subjected to extreme temperature changes -- conditions it will face during launch and its journey ...

The discoveries, published today in Nature Astronomy, challenge existing theories of our local interstellar medium ... in the plasma that exists in the space between stars.

A new model has been developed to simulate interstellar activity within our solar system and the nearby Alpha Centauri system ...

We now realize our local interstellar medium is filled with these ... the pulsar and plasma all move through space. From our vantage point, this causes the pulsar to twinkle, or "scintillate." ...
