    Are there stars in our sky which are less than 100 yo?

      Well, im not an astrologist, so I only know what I know from like… middle school class trips, but there are stars being born all the time im pretty sure :3

      Are they observable in our sky at a 100 years old? Probably not :3 space is massive so light takes a while to get here at that distance

        It’s all relative in space 😅. But I could reformulate my question: are visible today in our night sky stars that weren’t visible less than 100 years ago?

          Not exactly the question, but while looking into it I found this :3 a star visible once every 80 years

          The Milky Way is visible. It’s estimated that approximately 6 new stars are formed in the Milky every year.

          There are still stars forming, so probably yes if you use a super telescope

          In order for the stars to actually be less than 100 years old, they would also need to be with a hundred light years of us.
