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
