40:31they'd have to be damn close to be visible
40:34during human history ?
40:37and another billion died
40:44tl;dr you can't see the 7th star with the naked eye
40:48so it's assumed, not observed
40:49arent the pleiades in formation? their refl3ection nebulae is budling each star
40:49and we wouldn't for a million years for the light to reach us
40:50only 6 stars are visible to the human eye
40:55technically correct is the good kind of correct
40:55they are to far away to see
40:55As long as I don't have to smell uranus
40:57Yep, we only see the past, like millions of yeyin the past
40:59they're usually nebula shrouded when they're forming, so they're not naked eye visible
41:00there's no definite moment when a star turns on, there are many stars in various stages of formation though
41:03It'd be cool if it did, I reckon they'd make a big deal of it in the past
41:04i wouldn't worry too much about it
41:08Any that have formed since humans were born have not been around long enough for their light to reach us
41:10How would you know? We can't see their current condition. We can just guess
他
41:13i mean we can calculate the distance and the point in its life cycle
41:14No, because the present light hasn't reached us yet
41:18Size is usually the bigger indicator for lifespan of a star
41:19No, send a satellite lemon
41:23just give them a call
41:25Betelgeuse is closest to exploding at this point, but when it will explode, we will know
41:25The HH211-mm protostar, located about 1,000 light-years away in the Perseus molecular cloud, is only a few thousand years old.
41:26We can make a decent guess based on wavelengths and consistency but tbh not for sure
41:28It gets really confusing with relativity so I choose to not think about it
41:28don't red stars last longer?
41:30most stars don't die in a dramatic fashion too, they just sorta piss away their envelope and become white dwarves
41:31Isn’t that what light years are? You have to wait that many years to know if a star has died, right?
