The deaths of massive stars results in one of the most beautiful and violent events in the universe: the supernova. They are so luminous we can see them here on Earth and historical records show that we can even see them into the day. But supernovas release deadly and violent radiation that could destroy our atmosphere. So how far away do these supernova have to be for humanity to be safe? And when will the next supernova occur

Big thanks to the early gang! Because as noted a few episodes ago: Since our comment response livestream, we've noticed that YT isn't sharing our videos as much with our subscribers. So we're asking our subscribers to 1. switch their subscriptions from "PERSONAL" to "ALL" (just click on the subscribe button and you'll see it) and 2. Watch new episodes as soon as they can!
-
"Supernova Kill Zone" is a great album name.
-
Neat how the Supernova in the intro animation seems to be stuck in a geostationary orbit in the middle of the sky while all the other stars keep scrolling in the background.
-
Even though it’s incredibly unlikely, I can’t help but hope we get lucky and get to see Betelgeuse go supernova within our lifetimes. Would just be so cool
-
Matt is BY FAR my most favorite speaker. I could listen to this man for hours and I would never get tired, he's the coolest
-
TLDW? Summary: If you say Betelgeuse 3 times a massive star will explode in about 50,000 years.
-
I always love seeing the creative ways Matt finishes off with "Space Time" every episode!
-
It never ceases to boggle the mind that type 2 supernova are caused by the humble neutrino. A particle that interacts so weekly with regular matter.
-
Could you do a video on everything about light, like how it carries momentum despite being massless, and how it has polarization
-
Can you explain how the Romulans were caught unaware by the supernova that destroyed Romulus?
-
Notice how Matt specifically said, "Your ancestors," and not "Our Ancestors..."
-
I love when astronomy and paleontology connect
-
I loved the fact that Matt just knew everyone was thinking how far betelgeuse is and just answered it without a thought!
-
I for one have no complaint's about living in a boring "Goldilocks zone" of the universe. Humanity has enough on it's plate to deal with already. Thanks for the video.
-
That first pre-pre-pre-pre-stargazer was clearly a member of the Astronomopithicus genus
-
I just watched a video by Dr. Becky in which she mentioned that a new scientific paper calculated the time for Betelgeuse to go Super Nova to be decades / up to a 100 years. The paper has not been peer reviewed yet, but if it is true it might happen in our lifetime!
-
Matt is out of Gabes shadow. He's casting it on the other PBS presenters (maybe not that dinosaur bloke). Best compliment I can give. High praise indeed.
-
Eta Carinae is also a good candidate for a naked-eye-visible supernova (though not as close as Betelgeuse.) It's a wacky weird star though (two, actually), so its behavior is more unpredictable.
-
Crazy to think ghostly neutrinos have enough interaction to explode a star o.o
-
44 minutes after posting and there’s already a million comments? I feel like I’m insignificant among the stars.
