10 Things: Going Interstellar - NASA Science
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.
What is interstellar space and where does it begin? | Space
2023年1月17日 · Interstellar space is the area between the stars, but it is far from empty. It contains vast quantities of neutrinos, charged particles, atoms, molecules, dark matter and photons ranging from...
Interstellar: Crossing the Cosmic Void - NASA Science
2016年12月19日 · In this conceptual scenario, the disk-shaped probe in a bullet-shaped housing is launched as a payload on the Space Launch System, NASA’s next big rocket, in the late 2020s. With gravitational boosts from Earth, Jupiter and the sun itself, it …
Where Does Interstellar Space Begin? - NASA Space Place
2021年5月25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.
Interstellar Mission - NASA Science
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 and outward flow of the solar wind.
How Astronomers Define Where a Galaxy Ends and Interstellar Space ...
2024年10月15日 · In between galaxies are vast expanses of interstellar space — galactic deserts where you might be lucky to stumble across a few hydrogen atoms or, at best, a wandering rogue planet ejected from its home galaxy. So, where does a galaxy end and interstellar space begin?
What is interstellar space? - EarthSky
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.
The Voyage to Interstellar Space - NASA
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.
Voyager 2 Illuminates Boundary of Interstellar Space - NASA
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.
NASA Spacecraft Reveals New Observations of Interstellar Matter
2013年6月6日 · Scientists want to understand the composition of the boundary region that separates the nearest reaches of our galaxy, called the local interstellar medium, from our heliosphere. The heliosphere acts as a protective bubble that shields our solar system from most of the dangerous galactic cosmic radiation that otherwise would enter the solar ...
