The interstellar medium is an extremely sparse (tenuous) mix of gas and dust, some of the gas being ionized, some atomic, and some molecular. By composition the gas is largely hydrogen, with smaller amounts of helium and very small amounts of heavier elements. There are also cosmic rays which are protons and nuclei which have been accelerated to near-relativistic speeds.
In cooler, high-density areas, the interstellar medium can become as dense as one ten-billionth that of air.
Most of interstellar matter is composed of gas (mainly hydrogen and helium) and dust. The gas is primarily in the form of atomic and molecular hydrogen, while the dust consists of tiny solid particles made up of elements like carbon, silicates, and ice.
protostar or nebula
Yes, plasma is a state of matter composed of ionized particles, such as ions and free electrons. In interstellar space, plasma is abundant due to the high temperatures and energy present in these regions. Plasma plays a key role in the dynamics and interactions within the interstellar medium.
The word 'interstellar' in a sentence: The interstellar nebula was huge compared to the asteroid.
Strontium is an element it is made in stars and is blasted into the interstellar medium when stars explode. It can also be made in Human nuclear reactors.
Asteroid belt. They are not "interstellar", of course.

Visible light against electrons combined with ionized hydrogen create the "reddening" effect in the Interstellar Medium.

Interstellar matter floats around, and if enough of it coalesces, then it can turn into a new star or cluster of stars.

In astronomy, the interstellar medium [See Link] is the gas and dust that pervade interstellar space: the matter that exists between the stars within a galaxy. It fills interstellar space and blends smoothly into the surrounding intergalactic space. The energy that occupies the same volume, in the form of electromagnetic radiation, is the interstellar radiation field.The interstellar medium consists of an extremely dilute mixture of ions, atoms, molecules, larger dust grains, cosmic rays, and (galactic) magnetic fields.
The Milky Way Galaxy contains interstellar matter that may form new stars.
