The formation of stars has nothing to do with the expansion of the universe (to adjust your first response).
The more distant a galaxy is, the more its light is shifted towards the infrared end of the light spectrum. Imagine a rainbow, for a moment. The shorter wavelengths are violet. The longer wavelengths are red. Below the shorter wavelengths are ultraviolet, and shorter and shorter wavelengths. Beyond red light is heat, and various forms of electromagnetic radiation with longer wavelengths.
Visible light is only one small part of the spectrum, which includes radio waves, microwaves, and so on.
One very reasonable explanation for the "redshift" of the light from distant galaxies is doppler effect. You notice this with sound waves when you stand near a freeway. Cars approaching have a higher pitch than cars receding. This is because as they approach, they "catch up" with the waves they produce, so the spacing between the sound waves impinging upon your ears is tighter. As the car recedes, the distance between subsequent waves is increased, causing a drop in pitch.
Same thing happens with light. Einstein's General Theory of Relativity predicted the expansion of space. Einstein thought space ought to be constant, so introduced a fudge factor he called the "cosmological constant." After Edwin Hubble showed that the universe was expanding, Einstein referred to this has his greatest blunder. He would have won the fame and acclaim associated with the discovery of the expansion of the universe instead of Hubble had he only trusted his original theory.
The reason we find new planets is because we are developing better technology. The planets have long been there, we just could not see them before. New stars are also forming from vast clouds of interstellar hydrogen within our own galaxy, such as in the Orion Nebula (a stellar nursery), but our galaxy is not expanding, nor are the galaxies within our local group (those within about 10 light years of us). Andromeda, our nearest sister galaxy, is in fact approaching the same point in space we are.
Only over vaster distance is the space between galaxies stretching--10 million light years and more. Star formation is caused by the collapse of vast clouds of gas, not by the expansion of space.

According to measurements made by astronomers over the years, yes, the Universe is expanding and has been doing that for a very long time - since its creation.

Science is based on facts and not on belief s.
Astronomy is little better than astrollogy today and still is not a science truly in absence of fact/proof of so many running theories around and hence confusion prevails in the arena..
One topic is universe . How it was created or looked like at birth and how it has grown up like a living being and how it now looks like in space and time frame and when it will die like a man dies in old age and what will happen to it after death . Will there be a rebirth exactly simillar to its past life . Will the cycle repeat like Buddhas rebirth s indefinitely .
What is its day to day business now a days . What way the transaction of energy /gravitational pull/electromagnetic push/pull or centrifugal / centripetal forces take place between all those illuminating / nonilluminating apparently moving objects around . What is there in the seemingly void space .
Is the whole Universe vibrating like a single tuning forks /oscillating like a spring or a pendulum /expanding like a balloon during pumping in air or contracting like he ballooon due to a leakage/stationary in space like a floating balloon or soccer / leaping forward and backward like a frog periodically / translating along a helical path to and fro in space just like a nut moving along a screw / rotating like the contents in a mixie or in a spiralling motion along the surface of a conical space from vertex to base to and fro etc.
There are many a research papers published so far on these to satisfy public quriosity .They are perfectly and definitely good as literature for leisure . String theory is one such item which attempted to explain nuclear structure/universal structure /unification of natural forces in a package deal. Jurgons used some obscure terms and mathematical symbols which are coveniently understood only by the astronomers .
There is one major drawback in mathematics/computers today . It can not deal with infinity just like the way it manages imaginary or complex quantity / matrix arrays of finite no of rows and columns.
Universe is infinite and mathematics that are being used today is finitesimal . As long as mathematics of infinity is not well developed, the mystry about universe is likely to remain unsolved . We will be leaning back on belief to explain what mathematics failed to explain us.
I am inclined to believe that universe is dynamic and subject to spontanious / relative changes within it in time frame . Whenever movement or changes in one confined space causes its expansion , its adjacent space is undergoing contraction simaltaniously . Since the moving objects in space is loosely linked with one another and allows relative motion with respect to each other (e.g . elliptical orbit of earth around the sun ) , it is logically better to believe that creation and destruction or expansion /contraction is one simaltaniously occuring phenomenon rather than two with phase lag or lead and whole universe is not expanding or contracting as single entity. Nothing like continuous lenear expansion is possible as every object is moving in curvilinear motion .

It's not a question of "belief", it's simply a matter of fact. It's like asking if I believe in gravity.

Yes. The evidence would support that it is.

Yes, new stars are forming all the time. However stars die all the time too.
