what is interstellar space
Answers
Answer:
In astronomy, the interstellar medium is the matter and radiation that exist 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 the surrounding intergalactic space.

Explanation:
‘Inter’ means between. ‘Stellar’ refers to stars. “Easy!” you think, “Interstellar space is the part of space that exists between stars.”
Interstellar space – the space between the stars – isn’t just empty space. There’s a lot of “stuff” out there, including hydrogen (70%) and helium (28%), formed in the Big Bang that set our universe into motion. The other 2% of “stuff” in interstellar space is heavier gases and dust, consisting of the other elements made inside stars and spewed into space by supernovae. 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.
Our sun controls the conditions around our solar system, but outside of that is interstellar space and all that it contains.
