New stars form from the interstellar gas and dust; mainly hydrogen and helium.

The favoured hypotheses today are variants on the Kant Nebular Hypothesis, which have solar systems form from concentrations in the interstellar medium of dust and gas. Such a concentration may collapse inward under its own weight. At the center of collapse, matter may become concentrated enough to undergo nuclear fusion, at which time a star is born. Additional concentrations of matter in the region surrounding a newborn star may fail to reach that density, and eventually become planets.
Stars form when there is a sufficient concentration of interstellar gas, to begin the process of gravitational collapse into a star.
If it is not a gas, liquid, or solid, then it is a plasma which is a form of matter where the nucleus of an atom and its orbiting electrons are separated from one another. Another possible form that the matter could take would be in the form of radiation, where the subatomic particles comprising the nucleus of an atom have separated from one another. This form of matter is degenerated but it is not nonexistent. Another form of matter not commonly found within our planet and solar system is called singularity matter which is the matter found in the singularity of a black hole. This type of matter is compressed by gravity to the point that it acquires infinite density because there are little to no spaces between each individual subatomic particle. At such high levels of pressure, even electrons cannot orbit the atom and they are bound tightly to other subatomic particles.
The Milky Way Galaxy contains interstellar matter that may form new stars.

As interstellar clouds approach the spiral arm region it helps them to begin the collapsing process and eventually form a star.
Interstellar gas and dust.
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.
Yes - its another word for vapor - which is another word for gas, which is a form of matter.
Glowing cloud sections that will eventually become stars are protostars. These protostars are clouds of interstellar gas and dust, which gradually collapse causing a hot dense core to form and evolve into a star.
Petrodollar clouds form when a interstellar clouds begins to shirk. The clouds goes from interstellar clouds to petrodollar clouds.
Of the various types of matter that compose the interstellar medium, hydrogen, be it in atomic, molecular, or ionized form (e.g., protons) constitutes the vast majority of the material at over 90%. Helium forms about 9% and less than one tenth of a percent is heavier elements.
The interstellar medium is all the matter that exists between the stars in a galaxy. It mainly consists of gas (99%), with about 75% of this gas being in the form of molecular or atomic hydrogen, and about 25% in the form of helium. The other 1% is in the form of dust. The density of the interstellar medium is also very small: about 1 atom per cubic centimetre.There are two main types of interstellar mediums:Cold clouds of neutral atomic or molecular hydrogen, which are the raw materials wherein stars can be formed if it becomes gravitationally unstable and collapses.Hot ionized hydrogen near hot young stars.
A change of matter from one form to another without a change in chemical properties is a physical change.
