If you're referring to the space between solar systems: lots. Rocks and planetoids wander; radiation is absorbed and produced; space stretches; Von Neumann probes originating from long-extinct civilisations slowly make their way towards our solar system to convert it to rubble - you name it, it's bound to be out there somewhere.

∙ 14y agoThe interstellar medium [See Link] is the gas and dust that occupies interstellar space: the matter that exists between the stars within a galaxy.
It consists of an very dilute mixture of ions, atoms, molecules, larger dust grains, cosmic rays, and (galactic) magnetic fields. The matter consists of about 99% gas and 1% dust by mass.

The interstellar medium is enriched with heavy elements by the remnants of what?
The interstellar medium is enriched with heavy elements by the remnants of supernovas. A supernova is the spectacular explosion at the end of a stars life when it collapses in on itself.
Which of these is not a consequence of dust in the interstellar medium?
red light from the emission nebula
The dimming of starlight as it passes through the interstellar medium is called?
extinction
The dust particles have exactly the same chemical composition as the gases of the interstellar medium?
false.
How can you see through the interstellar medium?
by observing in high-energy wavelengths such as X rays and long wavelengths of light such as radio waves
What is the most abundant element in the interstellar medium?
Hydrogen

Which part of the interstellar matter produces reddening?
Visible light against electrons combined with ionized hydrogen create the "reddening" effect in the Interstellar Medium.

The dust particles have exactly the same chemical composition as the gases of the interstellar medium?
false.

Radio waves of 21cm wavelength originate from which component of the interstellar medium?
Cold atomic hydrogen
What events take place to indicate the birth of a star?
A child is born in Jerusalem. No, sorry, just kidding.Usually, stars are born as a result of nearby novae causing compression waves in the interstellar medium, followed by gravitational collapse of those spots in the interstellar medium that have reached critical density.
What is a galaxy in astrophysics?
A galaxy is a vast number of stars together with the interstellar medium and dark matter bound together by gravity.
