One megaparsec is 3.26 million light years. That is small. The sun is 4.5 billion years old, and should last a total of 9 to 10 billion years. Smaller stars -- red dwarfs -- can last much longer.
But new stars are born all the time, from the collapse of gas clouds in our and other galaxies. The Orion nebula, just 1500 light years away, is the site of the birth of stars, it is called a "stellar nursery".

One Mpc is "only" a 3 1/4 million light years and 3 1/4 million years is a short time in the life of a star. The Sun for example is over 4 Billion years old.

very sturdy question although, there are some ingredient's you've forgot to instruct. at the starting up, in case you're taking string idea and M idea into the mixture, then you truly locate that the preliminary theory of the enormous bang has countless flaws that necessary superb tuning. String idea is largely the theory that all count is produced from tiny vibrating strings on the sub atomic element. the concept appeared to artwork out, yet might want to no longer be a conceivable idea for the enormous bang, noticeably because string idea branched out into about 5 different idea's. Then someone pronounced that there will be an 11th length ( I swear i'm no longer bullshi**ng you about this, examine it out your self in case you pick) which merged each and each and every of the concept's lower back into one idea. And it truly is the position M idea is offered in.once you're taking the 11th length under consideration, then your strings seem to modify form, extra like rippling sheet's somewhat than a vibrating string. Scientist realised that those 'sheet's' the position a logical format for the universe, or maybe perhaps the multiverse. yet to make this a logical idea of each and every thing, then they could pick to describe the enormous bang. They realised that if 2 of those sheet's collided, then it may mealy create a universe in itself. Our universe. this can recommend there develop into no unmarried element of beginning, and that some section's of the universe are certainly a count of milliseconds to seconds youthful than others by way of rippling of those sheet's. I develop into hoping that a number of this would help you, yet i'm gonna keep your question in my recommendations, seeing as you've a element x

No - 1 mega parsec is 3,260,000 light years. Most stars last for billions of years, so in human terms, that's equivalent to about a week!

yes, these stars would be dead, but we see them the way they were several billion years ago.
