A super bright flash in the sky might be the birth of a supernova remnant and it turns out there’s more than one way to build a binary star system.

is hank wearing full body pajamas?
What would those stars look like from a planet?
I wonder what sunrise would look like in that binary system
Love yall
Can’t wait for turist poster of this BaBb system.
It makes sense, since the protoplanetary disk is orbiting the center of gravity, not either of the stars
The cow 😂
Go home, Space! You’re drunk!
Yay!!
If there are planets in that perpendicular system will their orbits be normal but just in a different plane?
Yay hank.
That was interesting.
1st comment or not!!
Thank for videos..
Good night from India..
Hank is the best
Brutal shirt.
I’m watching this while eating dinner. When you said “Not backwards but perpendicularly 3:02” some whiskey nearly came out my nose.
How do they know?? made up fantasy.
D’aaawww look at the little shiny ball of destruction, I could pinch its cheeks!
*perpendicular binary star system* _like, WTF!?_
How would the Sky look with such odd Stars? Is there an animation on that somewhere?
1.11 what do you mean shock wave?
What we are alone and we are just the first aliens XD
Awesome, however, what in the name of supernovae are you wearing man ?
Heck yeah I love space
I want to see a video representation of what the suns on a planet in that binary perpendicular system would look like in the sky during a day.
The main guy
the cow explosion
wow, imagine the sunsets and sunrises of this kind of solar system
Imagine trying to explain the seasons to a kid living on a planet orbiting HD 98800BaBb
I definitely felt a disturbance in the Force
too many cow puns down here.
without getting into how this system may have started (whether it being a perpendicular orientation from the start highly unlikely or if it developed this way over time) i ask this question to the SciShow Space channel:
Could it be possible that given the unlikelihood that the orbits of these 2 suns could actually sustain the continued development of the stellar disk, with the gravity emitted from them fluctuating too much to keep the stellar disk in a stable orbit, i ask you, could it be possible that dark matter (with the observations already made that it somehow helps keep galaxies held together) may ALSO aid in keeping planetary systems from flying apart too? (Is there anything i missed that flaws this question from the start? Just cuz theres a couple assumptions i made with this questions premise) I heard something like by the time one would reach the outer limits of the Oort cloud you would already be halfway to the next nearest star, even if thats not true, it just sounds to me like our entire systems total sphere of influence is too massive to be entirely dictated by the suns gravity, maybe dark matter plays a role at these smaller scales
That binary system must certainly have a few amazing spots for future turism photography… Imagine those sunsets and sunrises….
Hank is so cute, I love how excited he gets about science.
So from a certain vantage point on Earth we should finally be able to see . . . The Cow jump over The Moon . . . oh what wonderful times we live in lol
That feeling you get when a sneeze turns into a sniff…
I’m just going to come out and say what I think everyone is saying about that binary star system.
lol what?
Ain’t the plural ‘supernovae’…?
I would love to see what it would like to orbit a star pair orbiting each other
A planet around those two stars beats Tatooine…
Great video. Cool. Question: how long ago did this happen? Or did it happen in real time, as we understand time, captured while it was happening? Considering the speed of light etc. Curious.
Hank’s wearing his warmest clothing.
MindBLOWing event
The goldilocks zone around the perpendicular “Yo-Yo” stars is going to be really interesting. I’m also thinking whoever evolves there would have some great fodder for their mythology, and some complicated seasonal patterns. Maybe we should call it the Accordion System, and name the main life-bearing planet “AL.” Yes, you can call it AL. Of course, that could lead to other developments, like if there’s a special energy signature or interlaced spectral effects, that could be named “Yankovic radiation.”
“just as it began” … 200 light years ago.
Ok let’s be clear. The exact moment 200 million years ago in June. It was the same week that some early flat earthers inadvertently achieved space travel by falling into and then out of a coal mine shaft! It was located in the hand tossed area of the earth’s crust. They had been trying to debunk string theory in favor of flat earth friendly ribbon theory, when they were suddenly attacked by an enmysaurus during mating season! It was clear what transpired due to the obvious formation of a super massive black hole(wink wink nudge nudge) sorry that was my party goblin having a go at writing!
Less text please. I can use CC if I want to read what is being said.
I just hate it when the media doesn’t do research and just assume scientific discoveries are always true and publish them as click baits.
Supernova Cow al rescate!
Only 90s kids will get that one.
Since we know that Binary star systems happen, I’m curious as to whether Asimov’s “Nightfall” system is possible.
*thats a lotta damage*
Most interesting and informative.
Hank for President!
Failed to explode? That makes me laugh. A supernova dud.
The perpendicular orbiting stars might be the reason for the seasons in game of thrones.
Love seeing you over here Hank!
Hi, pedant here.
How many million years old is this new, to us, supernova?
😉
Loved the video! You guys should do one on the azotosome and potential biochemistry on Titan .
They’re all having a cow about it.
Heh
“The cow.” Scientists are SO good at naming things…
Don’t have a cow, Man!
Astronomy is the coolest s#!t ever. So much to ponder and observe. Out there. Right now. Something is probably looking out into it’s sky and wondering if we exist.
It’s hard to grasp that when I look up at Andromeda I am seeing it as it was when Austrolepithicus roamed the earth….or any such scenario…..
A supernova. How udderly fascinating.
I thought humans saw the crab nebula explode.
Was that a supernova?
That hair spray overload.. 👌🤔
I really Enjoy your Videos Hank !! Some of the Best !!
i was half asleep when i clicked on this but NOWWW IM SCREAMING, HANK WHAT ARE YOU DOING HERE <3 <3 lol
Ok, out of context time!
“The cow didn’t eject nearly as much stellar gas while its core collapsed as others do.” Ha ha ha
The COW died and stuff went missing. I blame the Hamburglar.
Okay, this is epic. Can we obliterate 50 neighbouring star systems?
Gotta love that nickname.
It’s a heavenly body, with these letters in its designation…
So, it’s a holy Cow?
Literally wish Hank could do all the videos lol
“Uncle Owen? Aunt Beru?
John Williams?
Great(!) Now we have to do the rest of the movie with Danny Elfman.”
Perpendicular solar systems… 🤔
When the odds are juuuust perfectly right and balanced 😅
#takethatnewton
1:02 Normal Person: Shorter lived. How long? A few seconds
Wait, A FEW WEEKS!!
*_…galaxies some-not-all already do this—with cores highly tilted from the spiral plane…_*
3:48 That sounds like a Sega Genesis code 🎮
Don’t worry, we can turn it back into a star using flex tape
I see Hank in the preview, *I CLICK*
So two suns are plausible. How neat is that?
A newborn supernova is cool, but glimpse the moment that two black holes merge then I’ll be impressed
The newly born Supernova (to us) might have grown a lot, it’s been around 200 million years.
The mythical spherical cow in a vacuum
We finally find the cow in the milky way.
Scientist are awesome. They become even more awesome when they nick-name a supernova “cow”. DFTBA!
So cute, things being born, can’t wait until heat death comes
Super Novas aren’t the most powerful explosions known to man.
My Sicilian Grandmother holds that distinction.
Hank you look super annoyed saying HD 98800BaBb. Lol.
I was -expecting- hoping this was about Betelgeuse, still hoping to see that.
edit: you know what I mean.
This was *super* interesting!
“The COW didn’t eject nearly as much stellar gas … ”
PLEASE tell me that was intentional..
If the Cow doesn’t have enough milk for its newborn, it is always welcome to our galaxy!
So not so much a cow as a calf, really.
Can this cow produce enough whey to satisfy my insatiable appetite for protein powder?
“Newborn Supernova” … Since a supernova is actually a _dying_ star, isn’t that like saying “a newborn _ghost_ ?”
Great video Hank. Thanks for the *outstanding* swirly-hand visual aid of the perpendicular gas cloud.
I used to work at Taco Bell, don’t tell me about the most powerful explosions in existence, I already know.
Birth of a supernova?? Thats like watching a person dying of old age and as they’re dying, saying “behold, the birth of a corpse!!”.
**breaths in**
*_ASSUME A SPHERICAL COW_*
1:35 “a lot of news outlets are selling this as way more definite”
Typical. They’re milking this cow for all it’s worth.
