To answer your question, in part, stars are still being formed (Rather, they were forming however many thousand years ago depending on the lightyear
distance from us) all around us, as the previous posters pointed out.
When a star goes supernova, remnants of the star are blasted out into space
(GIS for 'Supernova Remains'
. Barring collapse
into a black hole, these remains, these new nebulae, may in theory coalesce with other nebulae after thousands, if not millions of years of
gravitational tugging, creating a new Star Nursery*.
What this post is all about, though, is that Stars are simply gigantic fusion engines. As such, they have some loss in their operation. Feel that heat
on your shoulders? That is a form of radiation emitted by our star, and our star emits radiation in all spectrums*. The star emits this radiation, the
mass of the star is transformed into radiation, and the radiation bounces around space for untill it interacts with a mass. What I'm saying, in a
roundabout way, is that the majority of every star is eventually lost to radiation, which will not be recovered into a new star, unless we create a
solar-powered star generator. Unlikely. BUT. Over the course of our universe, everything that can be turned into a star will do so, untill it is all
lost into background radiation. At that point our universe will be, in as many words, dead.
*Also known as Academic Guesswork, I don't have anything to back this up. Especially the first statement. Just sorta logic-driven.
