How rare is it to see a star die?

Using our knowledge of the death rate in the entire Milky Way, the death rate for visible stars works out at about one star every 10,000 years or so. Given that all those stars are closer than 4,000 light-years, it is unlikely – though not impossible – that any of them are already dead.

How long does it take for us to see a star die?

Most stars will “live” for somewhere in the neighborhood of 1 billion years, so the odds are low that any particular star died during the past 10,000 years.

How many dead stars are there in the Milky Way?

It appears that our Milky Way contains at least 100 billion stars, while other more accurate calculations put that results at 250 billion stars +/- 150 billion. Black holes are dead stars, so they count as well, and there are at least 100 million black holes in our galaxy, the Milky Way.

Can you see a exploding star?
