     • 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 the highest-energy radiation to the sluggish light of the cosmic microwave background (CMB) albeit rather sparsely spread out.

   What have we learned about going interstellar?

   • Here are 10 things we’ve learned about going interstellar. 1. The Space Between 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.

   Is our Solar System in interstellar space?

   • In fact, part of our solar system is in interstellar space. How can this be? The definition of this interstellar space boundary is the region where the sun 's magnetic bubble weakens and comes to an end. This magnetic bubble — known as the heliosphere — is filled with plasma (ionized gas).

   Can humans go into interstellar space?

   • Humanity’s great leap into interstellar space – the space between the stars – is underway. NASA's Voyager 1 and Voyager 2 probes are both in interstellar space. For the moment, sending humans to the edge of interstellar space, let alone across the cosmic void to other stars, remains firmly in the realm of science fiction.

   What is interstellar space boundary?

   • The definition of this interstellar space boundary is the region where the sun 's magnetic bubble weakens and comes to an end. This magnetic bubble — known as the heliosphere — is filled with plasma (ionized gas). The heliosphere is blown by the solar wind that drags magnetic field lines out from the sun.

   How dense is interstellar space?

   • The material in interstellar space is very spread out. It’s denser in some places than in others, but a typical density is about one atom per cubic centimeter. Still, even the most dense regions of interstellar space count as vacuum, compared with our earthly air.

   • How Would We Know When We’Ve Arrived in Interstellar Space?

   At first glance, the answer seems simple. ‘Inter’ means between. ‘Stellar’ refers to stars. “Easy!” you think, “Interstellar space is the part of space that exists between stars.” Not so fast! Wouldn’t that pretty much mean that all of space is interstellar space? For interstellar space to be something different, then there must be some defined bou...

   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 Sun creates this heliosphere by sending a constant flow of particles...

   When it comes to the Sun it’s all about detecting the concentration and temperature of the particles around you. Inside the heliosphere, the solar particles are hot but less concentrated. Outside of the bubble, they are very much colder but more concentrated. Once you arrive in interstellar space, there would be an increase of “cold” particles arou...

   The Contents of Interstellar Space. Most of the space between stars is much emptier than the best vacuum we can make in a lab on Earth. However, it’s not truly empty: the interstellar medium (ISM) is complex, with a variety of physical processes governing its behavior.
