New stars form from the interstellar gas and dust; mainly hydrogen and helium.
They don't - new born stars and planets are formed together.
I guess that refers to the fact that matter from stars goes into outer space in supernova explosions, and part of that matter participates in the formation of new stars. Please note that this can't continue indefinitely; the percentage of heavier elements in this "recycled" matter increases over time, thus reducing the amount of fuel for new stars; also, when stars die, they leave a remainder - a white dwarf, neutron star, or black hole - that does NOT go back into space.
Two types of changes in matter are physical changes and chemical changes. Physical changes involve a change in appearance, such as a change in shape or state, without forming new substances. Chemical changes involve a rearrangement of atoms to form new substances with different chemical properties.
Nebulas are clouds of gas and dust in outer space, and they are where stars are born. The gas and dust in a nebula can collapse under gravity to form new stars. Additionally, nebulas are often illuminated by nearby stars, making them appear as colorful and glowing formations in the night sky.
Matter has two types of properties: physical properties (such as color, texture, and density) which can be observed without changing the substance's identity, and chemical properties (such as reactivity, flammability, and toxicity) which describe how a substance interacts with other substances to form new substances.
new stars can get matter from old stars and comets really anything it can get its hands on
The Milky Way Galaxy contains interstellar matter that may form new stars.
Due to the scientific law that states that matter cannot be created nor destroyed, it is extremely likely that all of the stars in our universe were formed from older stars that had released some or all of their matter.
From the material of old stars.
No, because matter can NOT be created
The two primary sources of matter are stars and supernova explosions. Stars produce elements through nuclear fusion in their cores, while supernova explosions distribute these elements into space, where they can form new stars and planets.

Constellations are imaginary patterns in the sky formed by stars. As some stars burn out, new stars form.

Stars form in all parts of our galaxy - not just the "arms". Stars do indeed form in the central bulge. The vast majority of hot, young, blue stars are formed in the arms, but stars also form in the central bulge as well.
A galaxy consists of stars, gas, dust, and dark matter. Stars provide light and energy, while gas and dust form new stars and planetary systems. Dark matter holds the galaxy together with its gravitational pull. Together, these components create the structure and function of a galaxy, shaping its appearance and influencing its evolution.
Interstellar matter floats around, and if enough of it coalesces, then it can turn into a new star or cluster of stars.
