2023年1月17日 · Interstellar space is not empty but filled with gas, dust and energetic particles. We explore this cosmic medium in more detail here.

2025年1月14日 · Scientists define the beginning of interstellar space as the place where the Sun’s constant flow of material and magnetic field stop affecting its surroundings. This place is called the heliopause. It marks the end of a region created by our Sun that is called the heliosphere.

The interstellar medium (ISM) is the matter and radiation that exists in the space between the star systems in a galaxy. This matter includes gas in ionic, atomic, and molecular form, as well as dust and cosmic rays. It fills interstellar space and blends smoothly into …

2020年10月10日 · Bottom line: Interstellar space is the space between the stars in a galaxy. It’s not “empty,” but, overall, it’s as close to an absolute vacuum as you can get.

2019年3月27日 · Now that the Voyagers are outside of the heliosphere, their new perspective will provide new information about the formation and state of our Sun and how it interacts with interstellar space, along with insight into how other stars interact with the interstellar medium.

2022年7月26日 · Interstellar space is often called the space between the stars, but more specifically, it’s the region between our Sun’s heliosphere and the astrospheres of other stars. Our heliosphere is a vast bubble of plasma – a gas of charged particles – that spews out of the Sun.

2024年10月23日 · The Voyager Interstellar Mission (VIM) is extending Voyager’s exploration beyond our solar system’s outer planets to interstellar space — the region outside the heliosphere, a protective bubble created by the Sun’s magnetic field …

Interstellar space — the region between stars inside a galaxy — is home to clouds of gas and dust. This interstellar medium contains primordial leftovers from the formation of the galaxy, detritus from stars, and the raw ingredients for future stars and planets.

2016年12月19日 · Space probe pioneers say the radiation, energy and particle-bathed space between the stars—the so-called interstellar medium—is itself a worthy science destination.

2019年11月1日 · At a distance of about 11 billion miles (18 billion kilometers) from Earth — well beyond the orbit of Pluto — Voyager 2 had entered interstellar space, or the region between stars. Today, five new research papers in the journal Nature Astronomy describe what scientists observed during and since Voyager 2’s historic crossing.
