- Neutron Stars, Pulsars, and Magnetars are the most extreme objects in the Universe that aren't Black Holes. Their extreme densities make neutron stars the densest solid bodies in the Universe ultra-powerful magnetic fields. When these fields sweep along our line of sight, we see them as Pulsars. Some Pulsars have have extremely strong magnetic fields. We call these objects Magnetars. And when a Magnetar has a star quake, the most violent explosions this side of a Supernova take place.

Great video. Any chance you could reduce the audio bass by 50% for your next video? Thanks.
Thanks for the feedback. Will certainly adjust for the next time!
Correction: Iron _can_ fuse, but it is endothermic, so it sucks energy -out of the star in the process. iiuc, this causes the star to collapse further until the temperature rises again to what's sufficient for iron fusion, where upon it sucks out the energy again, and it keeps collapsing until it rebounds and goes "boom" :)-
Correction to my correction! So the iron _core_ never actually fuses -- it is stable without any additional energy (due to electron degeneracy pressure) until the iron core (its self) hits 1.44 Mâ -- as you said. But when the lighter elements of the outer layers later crash into that neutron core, some of that will fuse into iron and most _that_ iron will fuse into heavier elements, since there's so much energy in the massive shock wave that the endothermic fusion is possible.
My apologies for the incorrect correction. Your statement that "iron can't fuse" is still incorrect, but I've had a wonderful time researching this. The great thing about being wrong is that it's an opportunity for me to learn something new. :)
What am amazing Universe we live in! Thank you for this wonderful video!
@@firstnamelastname9918 Don't be such a stickler. I am sure you know what your talking about but you fall into the category of 0.001% of people that would notice that and then still call him out. Then you called yourself out after that. I pointed something out myself but I was just giving a suggestion and not really correcting. I guess my point is: don't be what all the kids are referring to as a "Karen." A "Karen" is someone that goes around telling people that they don't even know when they are wrong. You weren't only a Karen to him... You were even a Karen to yourself. That makes you some kind of Super Karen. I've never even heard of that. I get your point and I'm glad to have learned the extra knowledge you shared but... I wouldn't do that anymore. It's a bad look. Seriously tacky to say the least.
"That's annoying." lmao. thank you.
I actually laughed out loud at that...
Your cuteness was like a magnetar to which I must investigate
@@pineapple7553 While I agree with you to an extent, we donât speak old English anymore.

10:47 here
"It would be the end of civilization as we know it. But, you'd be debt free." Nice one, Christian --- and: another great video!
Thanks Victor!
đđ -- I laughed pretty hard on that one, that was awesome timing! :-)
Those magnetars and crust quakes would be good stuff for science fiction movies.
Check out "Dragon's Egg" and "Starquake" by Robert L. Forward. They're both out of print but they're a great mini-series about astronauts who visit a neutron star and discover life.
@@LaunchPadAstronomy I still have my copy of Dragon's Egg! Good fun, even if the characters are a bit simplistic, the ideas are great!
Me too!
Sadly never saw a copy of Starquake. Must see if i can hunt it down, somewhere!
Just discovered your channel. Liked and Subbed!
Awesome, @@timbeaton5045 I'm glad to have you along for the ride!
Definitely my favourite objects in our often strange and bizarre universe. Millisecond Pulsars and Magnetars are insane things to think about.
Awesome, I'm glad I finally got to make a video on the subject, even though I barely scratched the surface :)
Awww my favorite object in our universe is you, Dave Kennedy!
@@scottydu81 same in return mate!
Such an awesome video Christian.
Thank you so much, man!
Thanks for covering this subject in this video! Pulsars and Magnetars are definitely the astronomical objects that amaze me the most after dark holes!
You bet, I'm glad you enjoyed it!
I really like your calm way of explaining these stuff. Not exaggerating or overreacting. Just plain and "simple" science, as it should be. Thats why these videos are so educational. Plus the little jokes in the middle are giving the much needed flavor to keep audience focused. You are good teacher!
The sounds of Pulsars always creeps me out for some reason. Awesome video. We are very Grateful âĄïž
Ha ha at "GPS", but this is great content. Hearing astronomical data is wonderful!
Thanks mate!
Today I learned that optical pulsars are a thing. Honestly one of the coolest things I've ever learned.
Best video about neutron stars I've seen so far
2:00 I love the analogy. Very helpful. đ
Your explanations of strange and astonishing things in astronomy are absolutely brilliant and really understandable. Thank you so much again!
Thank you so much for those kind words, I appreciate them so much!
I wouldn't worry about the nitpicking about your pronunciation, Christian. You're doing a fine job. Thank you for what you're doing.
Thanks Alex, much appreciated :)
The fact that neutron stars can get a millimetre high seems to speak volumes about the strength of neutronium
Another awesome video -- I learnt a lot, as always! Also, I laughed out loud at the "annoying" pulsar. đ Thank you for doing what you do!
Thank you Finn, I really appreciate the comment. Fires me up to make the next one!
Glad I found this channel. Quality content, congrats Christian!
Awesome Channel, awesome video my man! Please don't stop making these. Something about the way you explain the universe makes it great to listen to. I definitely recommend this channel.
Great video. I really appreciated your analogies.. You spoke in laymans terms and made mind melting concepts understandable.. It sat right in the sweet spot for my education...
I did feel the end where you âdefended yourselfâ to the comments is not worth the effort.. Im sure you feel itâs important, but as a viewer adds nothing to me.. as your channel grows it will only hold you back. Perhaps get in contact with Answers with Joe (Joe Scott) he does a great job of not getting caught up in the keyboard worriers.. I think he has another channel TMI where he can vent.
All the best mate, Iâve subscribed
Thank you for that feedback. The comment discussion was a first for me. I haven't done that before and thought it might be kind of fun. But yeah I should talk with Joe as he handles this stuff like a pro. Thanks again!
I took the part about pronunciation more as comic relief than actual worry about viewers opinions. Humor in judicious doses is never out of place. Just skip it if you donât care for it.
Edit. In case it was not clear I enjoyed it and found it funny and even interesting because I like language related topics. đ
Thanks Pat! I wanted to experiment a little and this seemed like a fun way to do it.
@@pansepot1490 I agree. It didn't feel like a grudge at all. It was actually a humorous way of bringing up the plethora of pronunciations that the English language allows and all of them have their reasons in their languages of origin or a speaker's linguistic variant. There's no "correct" pronunciation, linguistics isn't a subfield of ethics (the study of what is right). If anything, the only unethical behavior is shaming people for the way they talk. Most people will prefer to use the most common pronunciation simply because it's more effective at communicating. Personally, I think the way you (@Launch Pad Astronomy) pronounce is the best, the hard g is awkward and the "beetle-juice" is unnecessarily reminiscent of Beetlejuice.
@@LaunchPadAstronomy see answer above ;)
This is so cool! And incredibly well explained so that these complex topics are easily comprehensible without feeling dumbed down. Good job friend! :) and thanks for the video.
I find it so very impressive that successions of physics, cosmologists, astronomers and solar scientists have collectively managed to comprehend so much of the 'life cycles' of stars. The fact that we've collectively been able to understand such strange and exotic objects as neutron stars, often with mathematics at the centre; is astounding to me.
Agreed!
Thanks for mentioning my comment. First time a CZcamsr has done that to me. Appreciate it!
Wow! Great video! I subscribed the moment i watched your 1st video expecting good things and havenât been disappointed. Keep it up and i look forward to seeing you hit your 1st 100,000 subscribers.
Thank you so much, I really appreciate it! So glad to have you along for the ride!
Wish people would show more interest in Neutron stars like they do with Black holes. Could you do a video about theoretical stars; Quarks Stars, Iron Stars, Strangelet stars and Black dwarfs?
Thanks, I think those topics are pretty cool as well. I actually discussed black dwarfs as the end states of Red Dwarf stars (czcams.com/video/bBaTtKWcsrA/video.html). However, I made this video to act as a launch pad for follow-up videos to get into those other topics. Stay tuned!
FitnessONI I 100% agree I think that would be interesting separately because this channel goes in detail
I find them more fascinating. They are pretty extreme
Black holes will always be the King of weird, though. Unless white holes are discovered. Most people can already grasp the concept of a neutron star or quark matter. Many people can kind-of grasp a black hole. But I am confident there is even much crazier stuff yet to discover out there!
I am fascinated by millisecond black widow/zombie pulsars and their black hole equivalents. Regular black holes are boring, they only have mass and spin to describe them.
I love your explainations, videos and graphs, dude. Seeing things in such well designed context helps me a lot to understand the concepts you're talking about. Found the channel a week ago, and now I let out an audible "ooooh" every time I see a new video!
Wow, thanks so much!
This is some crazy awesome info. Thank you Christian.
love to see the steady rise of subscribers. Your channel deserves more attention and I'm glad to see it growing. Great video. The 2004 star quake is also covered by Deep sky astronomy for anybody interested in a short vid specifically about that event.
Thanks man, I really appreciate it. You rock!
@@LaunchPadAstronomy any time pal. You've earned it.
Just found the channel and the way you explain things are very easy to understand. Subbed and thanks.
And again an absolute great video!!!
Thanks! đ
These things are just and truly mind-boggling...that such extreme objects exist
If a Neutron star was an actor and the Universe was the stage it would get the role of "Jack the Ripper"
Clever!
Neutron Jack.
I feel more of a Dr. Manhattan vibe. But thatâs just me đđ»
I really appreciate and enjoy the ease and clarity in which you explain these facts; with a bit of humor and reality. At times it's difficult for our minute minds to concept the vast numbers in which our Universe operates! So fascinating! Quickly subscribed đđ
Thank you so much! I'm very flattered.
Excellent, clear, exciting explanations and well chosen images. Thank you! I feel that we need some mind-stretching to help keep ourselves oriented. Astronomy offers many chances for this, and neutron stars are great mind stretchers, especially as you describe them.
Thank you very much for those kind words. Astronomy is a very humbling endeavor.
The Universe is awe inspiring beautiful and intensely horrifying at the same time đ€©đ±đ
Indeed it is!
Great video, I love how illustrative it is, well done! :)
Thank you so much!
Learning so much. Really happy I found your channel today!
Thanks, Iâm glad to have you along for the ride!
My new most eagerly anticipated channel!
Thanks Brian!
Great video Christian! Many thanks for your clear explanation
Thank you, Anne!
Christian Ready made a leap in presentation style. Good to see you are back, the long pause before the Betelgeuse video had me a tad worried
Thank you so much. I did release the supernova video when I returned. Itâs good to be back in the saddle again!
Ty for talking about Magnetars, i never hear much about them, & they are my fav when it comes to pulsars quasars & magnitars
Great content. Like the way you contextualise these galactic phenomenon in humi terms.
Thanks!
Relative Concept of "Now".. well saidđđ Great Video too!!đŻđâïž
Thank you for the cool viewie. Very informative please keep it up!!!!
I canât fathom that kind of spin rate for something so massive
Me neither, and yet it spins :)
Very nice and interesting video. Many thanks Christian.
I learned so much from this video! Thanks!
Wow, after Billions of years, it only takes a few milliseconds to collapse and maybe SUPER NOVA EXPLOSIVE đ§šđ§š
Amazing explanation! Great video
It's the first time I've come across your videos. Great stuff! Subscribed âïž
Wow, thank you! I'm glad to have you along for the ride!
@@LaunchPadAstronomy I'm looking forward to it, and thanks for the response đ
Your channel is a goldmine. Underrated
Thank you so much for those kind words. I am, however, looking forward to being overrated someday :)
Another great video, I really enjoy them. In relation to Betelgeuse I've always pronounced it Be-Tel-Gaze. Keep up the great work!
Thanks, I'm so glad you enjoyed the video!
That was really interesting. I subbed.
That repeating radio signal for that pulsar hits different, can someone make a beat outta that?đ
lol!
I've been studying this for a few years, glad I found your channel, you Sir, have a new subscriber, Thanks.
Long live the Universe. đșđž
Thanks, and delighted to have you along for the ride!
Thanos squaring off with magnatar* "Our battle will be legendary"
đ€Ż great video! Very engaging, thank you!
Really interesting content. Great analogies
Thank you so much, I'm glad you enjoyed it!
This was a pretty fun video :) I liked the little subtle jokes in there.I tend to wonder, if all this was humanly possible to surive if we could witness these events up close, would they be visible? or would it be energy? I guess energy is light, so it would probably be blinding, but it would be interesting to "witness" these events in a "normal" manner. Especially the rapid expansions and contractions, the idea of mass shinking so rapidly blows my mind and I'd love to witness that first hand
Thank's for helping a family member understand what's part of my interests.
đ
A guy named "Christian Ready" running a science channel. That's awesomely
Statistically mind blowing . Quite amazing that my neural galaxy can actually perceive it , considering the difference in scale.
The energies, gravities and densities at work are simply incredible! I had no idea Earth was hit with a leftover sun quake from a magneton star that far away! I'm curious how many civilizations were affected other than ours.. if they are out there which I'm sure they are..
It really is mind-blowing stuff. I wouldn't want to be within a hundred light years of one of those starquakes. As for any civilizations closer, I hope their life insurance was paid up ;)
Thank you Christian, for introducing me to magnetars. . . freakin' mind blowing!!! đź
You bet, Patrick, and thanks!
15:37. "We're always seeing into the past thanks to the speed of light. That leaves us with a relative concept of 'now' "đ
To quote SpaceBalls: "When will then be now?" "Soon!"
If the only thing you can think of as a supernova engulfs the earth is financial debt and Tesla's, then maybe the supernova should have come sooner... In all seriousness very informational video with some helpful metaphors for understanding Neutron Stars!
Subscribed! Neutron stars are wonderful
Thank you so much Nyar 23, and indeed they are. I'm glad to have you along for the ride!
Great work ....good informative video..
"Stellar Mutant Power Zombies" sounds like an awesome band name.
8:53 - The Sound of the Vela Pulsar - "Get to the choppa!" - Dutch, Predator.
Pronunciations can be a personal thing. Prior to the Americanised "Beetlejuice", the common used pronunciation in the majority English speaking populace was "beh-tel-guze". The pronunciation I among a lot of others still use. So someone saying it is wrong is talking through their arse. BTW, excellent video as always.
I'm sure they mean well, even as they cuss me out :)
Thanks
This is an excellent breakdown of these amazing objects.
Thanks!
Great video đđŒđ
I like your button up shirt. Interesting video. Those star quakes are scary. It would be great if we had some kind of early warning system and develope some kind of defense sheilding
Nice video as always
Thank you, Anna, itâs much appreciated.
A fine primer, easily absorbed. Liked and shared.
Thanks, I'm glad you enjoyed it!
Cool Video đđ»đđ»
I once saw a Neutron star in Elite Dangerous. It was a sight to behold.
PSR B1937+21: *screams in pulsar*
Christian : that's annoying.
Nearly fell off the floor from laughing. Thank you for the great video.
alex burgess thanks, Iâm glad you enjoyed it đ
This video is wonderfully informative and delightfully amusing
Quantum goo-
It's Weird!, Great video once again!
I'm glad you liked it!
Superb thank you.
Pretty nice video.. Thank you Sir for the information. Keep it up.. Love from India. love from Punjab.. Stay Blessed
Thank you!
A very great and interesting video! Easy to understand even for someone who doesn't speak/understand english that well.
Your voice is so clear, what's the microphone did you use?
Found your channel this morning thank you CZcams suggestions! Awesome stuff and you pronounce words how you like never mind us keyboard warriors! :)
Lol thanks, and Iâm glad to have you along for the ride!
Pretty fooking informative..nice one
Thanks!
Thanks. I've watched a couple of your videos now, and you're now on my list of favorite channels. Also, it doesn't really matter how you pronounce Betelgeuse, as long as you don't say it three times in a row. tavi.
That's why I only made two videos in a row on Betelgeuse.
I stumbled upon your channel and found your way of communicating science quite amusing so I subscribed.
Just a little suggestion though. I think you should try to keep the length of the videos under 12-13 minutes. Nowadays the audiovisual material on the Internet is so abundant and the attention of the public so scarce, that it is difficult to spend time watching everything one would like to see regardless of how interesting it is.
Well, that's just my opinion anyway.
Thank you very much for the feedback and those kind words. I'm personally not a fan of overlong videos myself. I try to make them as long as they need to be but no longer. I ended up keeping a lot of content out of this one but looking at it, I can see where I could have cut or phrased something shorter. Appreciate the feedback, and I'm glad to have you along for the ride!
@@LaunchPadAstronomy
You may also want to consider presenting a topic in more than one video. Neutron stars episode 1 and so on. That can also create some suspense and interest in people wanting to watch the next episode.
Fascinating video. Imagine the Incas floating directions to the Spanish. We have Voyager. The people with PHD's were naive at best, and fatally mistaken at worst.
The other observation is the distances mentioned, and how we are unaware of events which happened even hundreds of years ago due to the light not having reached us yet. This indicates disaster could be revealed at relatively short notice any time.
The Speed of Light is a mega mindfuck.
I actually learned some new things about neutron stars!
Massively magnificent Angry Cloud Alpha Orionis!!
Cool video bro. I have a question is the crack in the crust a micron wide or a micron long during a â quake.
Nobody:
PSR B1937+21: REEEEEEEEEEEEEEEEEEEEEEEEEE
Thank you sir.
magnetars are fascinating
indeed they are
Nice đ, informative!
Glad you enjoyed it!
Utterly fascinating
