There should be millions of stars out there where death and birth of stars should be happening quite often. Why are we not seeing these? Is space just too big

There should be millions of stars out there where death and birth of stars should be happening quite often. Why are we not seeing these? Is space just too big for us tiny human beings to observe them?

Stars last a long time, so even though there are a lot of them, they don't die that often.

  Some sources claim that about one star per year in Milky Way dies. We have about 100 billion visible galaxies, so roughly 3000 stars per second die in our visible universe - however, most of those are small stars which aren't really visible to our instruments.

    Small stars live a long, long time. We shouldn't see them die, yet.

      They were born long, long ago as well.

        Red Dwarfs are expected to burn for trillions of years.

We see supernovae regularly and observe the aftermath within days of the event. What is special about this one is that TESS happened to be observing it before the explosion.
