It is mainly in supernova explosions that part of the matter of the star - NOT all of it - goes back into space; as a result, some of it eventually ends up in new solar systems, such as our Solar System.
The result of this is that our Solar System has some heavy elements, which were not present when the Universe began.
Please note that this "recycling" can't go on forever. Part of the mass stays in the star remainders; a supernova may collapse into a neutron star or a black hole. Also, the matter that goes out into space has more heavy elements than the original mass of the star that went supernova. In other words, it contains less hydrogen, which is used as fuel for stars.
interstellar extinction. This phenomenon occurs due to the absorption and scattering of light by dust and gas particles present in the interstellar medium, leading to a decrease in the observed brightness of the starlight.
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.
By using various wavelengths of light, such as infrared or radio waves, we can see through the interstellar medium. Different wavelengths can penetrate the dust and gas in space, allowing us to observe objects that may be hidden in visible light. Telescopes and instruments that are sensitive to these wavelengths help in studying the interstellar medium.
The interstellar medium is enriched with heavy elements by the remnants of supernova explosions. Supernovae are massive stellar explosions that release heavy elements such as carbon, oxygen, and iron into space, enriching the surrounding interstellar medium with these elements.
One consequence of dust in the interstellar medium is causing reddening of starlight due to scattering and absorption.

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

A galaxy is a vast number of stars together with the interstellar medium and dark matter bound together by gravity.

Gravity plays an important role in the birth of a star. It concentrates matter in the interstellar medium to the point where fusion occurs.

Hydrogen is the most abundant element in the interstellar medium, making up about 90% of its mass. Helium is the second most abundant element in the interstellar medium, with trace amounts of heavier elements such as carbon, oxygen, and others.
