Shout out to our guy Anton for scouring scientific papers on the daily and keepin' us current. Do you just read all day my dude?
Seriously. His effort has got to get recognized amongst the YT community. So many channels spew out misinformation just to be able to get content out. People know they’ll get clicks because of ignorance.
Good freelance science journalism has come into its own with people like Anton. And great to see an appetite for it.
I usually skim through abstracts only until something catches my eye. Also a lot of them are often shared on arxiv daily, so setting up a good script that catches specific words makes it fairly easy. But there is usually one entire day dedicated to a lot of reading and that's today
@@whatdamath thank you for your good work and the information you share Anton :))
I enjoy your content a lot
@@whatdamath Great work dude, awesome, you have made the inaccessible accessible and entertaining to a wide audience.
Anton is the best UA-camr for science. They should use his videos for classroom instruction
11:16 "like this little guy"
Its so heart warming to me for some reason to hear Anton being friendly with an animal that died millions of years ago
The animal would have liked him, too... (maybe as a snack, but still...)
We keep learning things, and the more we learn the more we realize just how lucky we are as a species. Hope your move is going well, be safe
It’s insane to think of how unbelievably RARE we are as a species. Like in a scale we probably cannot grasp.
@@joab757 It is insane to think of... so I don't!
Just kidding, I'm here aren't I?
Then take another moment and realize that you lived in the age of Van Halen and how lucky that is in the scope of time since the BB
In "Hitchhikers guide to the galaxy" It talk about the strengths of the galactic species and mankind's special gift was it's incredible luck . Narrowly escaping extinction time after time.

Anton We Love your work. I recommend you to everyone I talk to!
This guy on his own is better than my entire history of popular science magazine subscriptions.
Hail to the king of scientific journalism
Betelgeuse may have exploded sometime in the last 640ish years and we just don't know it yet.
ikr people forget how far away it is!
Lol
People also forget how slow the speed of light inside a star actually is. Light takes 100,000 years to get from the centre of the sun to the surface. More like the speed of sound than what we normally think of as the speed of light.
As long as we don't see it, it cannot harm us. Because light is the fastest.
Karm Esnom No. The speed of light is also the speed of time.
Great Anton! really like your videos!! Hope you're doing well.
Beautiful person :)
An old buddy owned a 1969 Chev Nova SS. That was a super Nova.
I helped build a '70, into a .383 stroker 😎. Love me some Nova
Huge fan of the early Nova 2
@Podkova apparently sold well in latin america despite the translation.
@Podkova Nova also means new. The female version of new. At least in Portuguese.
Novas ❤
10/10❤️ Aton Always a great job Sir. Love these little lessons. The best UA-cam rabbit holes to fall into. Thanks man🙂
Glad I hopped back on! MORE ANTON!
I was getting a lil worried he wasn't gonna say hello wonderful person 😁
Hey anton. Keep up the great work
Great presentation Anton, thank you.
Make sure not to say Betelgeuse 3 times in a row, Anton :)
@ritemoelaw_books83 play on "Beetlejuice" Michel Keeton
1980s...
@ritemoelaw_books83 You nailed it. say it 3x and you're annoyed by a jack ass for eternity :) Fun old movie
Nobody ever says anything 3 times in a row, except theire told to not say a word 3 times in a row. The they surely will do it ....
...bloody mary
He started one of his videos about Betelgeuse like that.
Anton your videos are some of the best I have come across in a long time, keep it up! As an astronomy student I love learning more and more about the stuff I love from you :)
Check out "Dr. Becky" - She just did a vid on the Nobel winners w/r black holes.
Wow, the work Anton does for this channel is simply amazing. And the quality! Thank you Anton!
Thank you Anton for the post as always. This is one of the few actual news channels on this platform and I wish I had the resources to donate on a reg. Basis, Im hoping your channel will be around long enough that I can order a 'wonderful person' shirt :)...
So hopefully you will find the answer your looking for Anton.
All blessings

Man, thanks for sharing the science!
I have always thought that the solar system stayed in the spiral arm in which it found itself... that the spiral arms and their contents orbited the galaxy center intact. If you watch Anton's channel you stand a good chance of learning something new every day.
It's funny, as soon as you said "it's not something we have to worry about just now" (paraphrasing) the first thing I thought was "yeah, we've all heard that one before" 🤣 😺 🐾 ♥
haha .. look, if we could survive for 100m yrs without being spacefaring civilization, then we deserve to die
Thankyou Anton! Hope you are doing well.
Anton is warming up for his second possible career, stand up comic. But you LEARN something at the same time. !! Go Ant.
Anton, great presentation, as always. Alas, like with climate change, a local "bit" possible player not mentioned is our Sun! As I've seen mentioned on one of the vids from the Suspicious Observer channel, there are currently 13 known stars observed by astronomers that have nova'ed, in which the nova'ed stars still remains. In their stellar catalog, these 13 stars are listed as having prior nova events.
It appears that the outer shell of those particular stars is what exploded and not the entire star, which is what a classical nova event exhibits. The term coined for these events is "micronova". 2 mechanisms is proposed to cause this action. One is the galactic dust that accumulates onto the surface of the sun, the triggering of the blast occurring from the pinwheel dust effect from the galactic motion sweeping in from the galactic bars "enriching" the solar dust accumulation. Go to the Suspicious Observers site for a more detailed explanation of this fascinating process! Can't offhand remember the other process - guess I'll need a refresher on the topic🤔. The Apollo missions to the moon resulted in the discovery of heavy elements found on the surface. Novas are known producers of heavy elements. There are also mocrobeads which exhibits subatomic streaks internally.
Hey, this reminds me of another of Anton's vids! The one concerning the orbital dust rings found around the planets, especially Venus from a goof of the new Parker Sun probe. He could not account for the majority of the dust forming from the planets and sun to fit the observations. The external waves of galactic dust could be the "missing mass" necessary to account for the dust to fit the observations.
About the "micronova" suns. Due to the composition, size, etc. its conjectured that most, if not, all of the stars have micronova events. Most are of such long periods that our relatively short observation records haven't recorded their second "boom" events yet.
Out solar micronova events appeare to exhibit a 12,000 year cycle.
All of above gleaned from Suspicious Observer, Sky Scholar, etc YT sites.
Anton could discover something interesting to say about the "boring billion."

Thanks for all you do, Anton.
Cheers from Downunder.
im happy for you when you reach your 1 million subs! this is quality content, delivered by a very calm person, no bullshit, no gimmicks. 10-12 minutes is cool, as long as you fill it with information and this is the case here. other channels do 10minutes videos to gain more money.
Thanks Anton - a timely and important report. Hope the next one doesn’t happen soon.
Thank you Anton.
More fascinating information.
Thanks for keeping us in the cutting edge of knowledge (in this field, at any rate)...
Enjoy all your videos. Great day!
It's looking like our Sun has cyclical micro-nova. Possibly twice per each of Earth's precessions.
5:11 the chain reaction is known as a trophic cascade
Sure, it's the same number of words and syllables, but it just sounds so scary! 😁
Your channel was the best thing i found on 2020. Thanks man!
Thanks Anton for explains so many ‘knock on ‘ effects of far away cosmological events !
what about the 10c degree swing that happend around 13500 years ago?
according to carbon deposits on the north/south pole?
Milankovitch cycles.
Anton: makes a video about us flying through a supernova right now. Also Anton one day later: talks about supernova extinction events ❤️😁
Anton you are the best at explaining. You get right to the point! You cover a lot in every video! Thank you!
If the 60 million years ago extinction was caused by an asteroid impact, and the 365 million years ago was caused by a supernova explosion, then both extinction events were generated from outer space. Very interesting Anton.
Of all the possibilities that have been brought to attention, this one may have more than a grain of truth ...
Comments are good for the UA-cam algorithm.
I can’t be the only person who’d love to grab a beer while bar-hopping and hanging out with Anton.... you’re the best my friend!
Your videos are amazing Anton...Thank you for sharing what few of us are even aware of! A light in dark times. The beauty of the unknown makes me appreciate just what we have here!
What was Mars like as a planet when this happened?
🤔 or Venus ?
well Venus went extinct 666 million years ago. 666 haha get ur laughs out. mars went way before that.
Tri Thank you for the response. I’ve decided to learn more about all that.
Counting on a nearby supernova to happen before New Years.
It would rap this year up nicely...
C-S featured - it’s 2020, wouldn’t be surprised
@@neverlistentome Lil' Nova
There's no likely star nearby.
Adapt 2030 my friend
I hope you are doing well Anton and a huge thank you for making your awesome videos. I love 💕 watching them and I learn so much from them. I hope you have an awesome day and I look 👀 forward to your next video 🙏🙏🙏😃😃😃
Thank You Anton! You are the man! I really enjoy your channel! I want to buy a shirt and will ASAP! Keep it up!
You could say this is an *explosive* new discovery 😆
Earth: takes a lickin' but keeps on tickin'
Love your work and presentations. Thanks. Bless your life 💚
thanks dude. enjoy your videos
And IT Will happend again No matter how smart we think we are.
Why would smartness matter? 🤔
Yes it will happen, but forewarned is forearmed. Regardless of smarts, it is best to believe it’s possible to mitigate the effect.
@@paulembleton1733 oh yes and thats why we still is here.
Well, we've been smacked by at least 2 rocks big enough to ruin our day and there's nothing we can do to prevent the next one.
What our smartness has to do with supernovas, just out of curiosity? Or have you only tried (and failed) to say something intelligent? :D
At 10:00 - this makes no sense. The arm will be orbiting around the galaxy at roughly the same speed as the sun is orbiting. Why would we ever catch up to the arm?
igelkott255
Stars orbit at different speeds and they can slow down or speed up because of the gravity of other stars. This has the effect of causing the arms to ripple a bit like a flag in the wind.
I get that... it just seemed unlikely to me that the speed differential would be that great that we'd get anywhere near it it only a million years.
Interesting topic. Thank you for the video. I have reached out to NRAO to see if we could detect the interactions of past supernovae on nearby gases to triangulate a point of origin and see if any supernovae actually did explode in the proposed time frame.
Excellent quality video! I am a medical student, hence, this is not my forte, but I did learn quite a bit of interesting things. Keep it up! You have yourself a new subscriber.
You noted that our solar system changes it’s position relative to certain features of our galaxy (the spirals in this case) as it rotates around the galaxy. Does this mean that our solar system moves at considerably different speed than the stars in the spirals (which I would expect would also be rotating in the same direction)?
Legend has it that if you say "Betelgeuse" three times into a neutrino detector that you'll start a supernova.
yes!! thank you; always nice to watch and learn new stuff
Best. Channel. Anywhere.
Anton: The chances for a supernova near us will only increase in about some million years or so.
2020: Wait! I'm not finished yet.
I'd worry more about 2022. Just because 2020 was bad, doesn't mean anything is going to get better.
Didn't you just put out a video that was questioning if we are in a supernova cloud...now today you posted a video saying an extinction event might be from a supernova? 🤔👍
Baby steps.
Great presentation enthusiastic presenter and new insight into our corner of space. Really, really big.
Anton's my favorite
A SuperNova exploding near Earth, in the year 2020, would be a fitting Swan Song for “ungrateful humans” the way things have been this year!
"Boring Billion' xD nice era name
Thank you for again sharing your knowledge.
Love this channel!
Can you please make an animation on how close the stars are at the centre of our galaxy ?
Could it have been our star that ejected the material?
Unlikely, most activity in our sun is simple hydrogen to helium..... Heavier elements later .....
Ive been tracing and reading the scientific papers you mention in your videos mind blowing
Another outstanding video Anton!
Anton teasing a star...
The tiger at 6:45 just looks so done with everything.
Another good show Anton!
Really interesting - thanks Anton.
Mini nova event happens more often.😂👁👁🇺🇸
Take a drink each time Anton says "supernova"
💀
Dude......y'r my .....best frein' evr..........What're you lookinat?
Get wasted😀
Rich Mitch I’ll try with smoke. I don’t drink.
Makes sense @@volcaniicash6485
Then down that 🍻 like it's going to be your last.
I found this channel about 1 week ago based on a UA-cam suggestion. I was hooked! My son walked past me 2 days ago and said "Are you watching Anton?" I said, "yes, you watch him?" He said, "yes, he's great!" I'm sitting here thinking of all the times he had me watch videos I could care less about and never mentioned this channel. I have LOTS of catching up to do! :)
Love your videos!!!
1:27 is that real or simulated? Never seen pulsar images before. Looks cool.
I think it is ur mom
If theres enough radiation to wipe out the ozone layer, maybe those arent just UV burns....
Very well presented. Good job. Interesting.
Thanks! Loved your extinction intensity graph at 9:03.
It is amazing though all this death has happened in the past yet the Earth survives and life continues, until the next SNE occurs.
Eventually he will wake up to the fact out own sun regularly micro novas.
i thought micronovas dont exist lol
lol i love you intros. keep em comin
anton your education for us lay people is amazing. thank you and God Bless You!
could be, but wouldnt a magnetic excusrsion and a nope,micro nova from the sun satisfy things, not kidding, our son pops off micronova periodically .
Yup teenagers sure do get moody
Just wait until they "discover" that our sun is going to micro nova (again) . And that is what has caused the major extinction events of our planets past.
They know it, just not going to say it.
Huh?
Where can I read about this?
@@Zorro9129 go check out Diehold Foundation channel on UA-cam. He has lectures on the subject.
👍🌏🐨 Anton. good to see you back .i follow and do understand your videos. regards .Keith Australia
Love your videos you make it understandable for people like me.....
Could this not also be a micro nova from our own sun?
the star right next to us seems most likely to me as it seems to me we just don't know that much about such things yet
@@smithcs790 Yeah, we don't seem to know anything really. But we think we know a lot.
Wouldn't the other parts of the galaxy (like the Orion Arm) also be orbiting around the galaxy? So how would the Solar system reach them?
Right, i've never heard of this moving through different arms stuff, those stars are also circling in the galaxy.
Yes. But, stars are also gravitationally attracted to each other. And therefore, are circling each other in a cosmic dance. All the stars in our galaxy are circling the galactic center but, each star has a slightly different speed.
Hi wonderful person....thats a nice greeting. Enough to make you subscribe. Thanks Mr. Anton. Your videos are addictive.
Mate I really enjoy your vids

damn i thought i was the first..... i just get notification and came right away but alast
Reminded me of an idea I had - I wonder what would cost the most for a mega project : refilling the ozone layer after a nearby supernova, or building a massive space shield that we could move around to block us from a predicted supernova.
Producing ozone happens accidentally all the time, but is usually avoided for obvious health reasons. Laser printers can produce them, for example, but we've managed to deal with it well enough and it breaks down quickly back to oxygen.
The deliberate creation on massive scales can be done, we could even trick nature in to doing it for us by forcing lightning storms. Given the run-on effects of that, I think we'd care less about it than the potential extinction of large chunks of life on the planet versus some potential floods, fires and lightning-related deaths.
Definitely an interesting idea to think about. By the time we reach a potential supernova threat, it'd be a non-issue for us anyway. If we even survive our own stupidity!
i love this channel !!!
