kilonova: When Neutron Stars Collide

We all know that neutron stars are pretty extreme stellar phenomena, but what would happen if two of them ever collided? Welcome to the strange world of the kilonova. Let’s find out more.
Kilonovas get their names from the fact that they are 1000 times brighter than a nova. This does mean that they are about 1 tenth to 1 hundredth the brightness of a supernova, and because of how they form they are incredibly interesting indeed.

The thought of an object (especially an object tens of kilometres wide) completing a orbit 1000 time in a single second is awesome in the true sense of the word. I actually paused the video to think about that...such phenomenal speeds. This is why I enjoy the subject of space and why I enjoy this channel so much. Much love for your videos 👍🏼.

Unrelated fun fact: Solitary stars being relatively rare might be at least a partial solution for the Fermi paradox. Maybe life is too rare in systems with multiple stars.

Neutron star material can only exist under the compression of extreme gravity. Knocking any of it off (as happens when these stars collide) releases some matter and a huge amount of energy.

your channel, videos, story telling and animations are beautiful. thank you and keep it up

This video was in my feed. I clicked, because it could be interesting. It was very interesting, and it was superbly well done. I figured it earned a like, and possibly a subscription.
Turns out, I was already subscribed. Nicely done past me! :)

Don’t even care bout midroll padding due to the fact that it is really good content either way!
This feels like the definition of the “I’ll allow it.” Meme

If you try using just grid lines to map the black hole in 3D space, i.e. just showing them converging to a single point, it makes it slightly less of a mess. Well produced. Nice job.

It's quite amazing to think about all these processes, everything around us, light, stars, planets, gravity, quantum mechanics, it's just there, happening, regardless of any observer, regardless of any conscious minds to understand it or eyes to perceive its shapes and forms. In reality, without an observer, in the non-existant perspective of, say a planet, or a proton, everything is happening in darkness. It just "is". When we are all gone, everything keeps happening without us and "it" doesn't care. The fact that we are here, that we have come to this point in time where we are able to even begin to understand how things work and explain it, is absolutely crazy.

2:00 Two stars form a purr. LOL The Brits, gotta love em.
6:00 A sheet of robah'. He's better than some comedians I've heard lately.

I like how you make up your own words that are completely understandable 😆

5⭐⭐⭐⭐⭐ video. Thanks. I just subscribed. Would love to be there with you watching the light show. Looking forward to more.

Neutron stars- beyond mind boggling, these exotic objects, these utter beasts... just amazing, terrifying, but amazing

[AmaroqStarwind]

I wonder if we could harness gravitational waves for useful energy production.

Picture... A Thorne-Zitkow Object (TZO), except the neutron star at its core is a Magnetar, and the red giant is instead a blue supergiant. And then that modified TZO starts orbiting a black hole of equal mass to itself.

That would be pretty awesome to have an artistic depiction of.

Loved this video, great graphics and interesting topic! 🎉❤

Me: Here, have some spinach, it's high in iron. It's really good for you.

Sun: Aw, thanks tiny human. This is delicio....
_I don't feel so good_

Me: _evil laugh_

Will enjoy this channel building to hundreds of thousands of subscribers, he deserves it.

Space would be the ideal environment to build much larger LIGO detectors, they could be 3 dimensional and positioned 2 or 3 AU apart

Just found your channel today and loved your video thought about subscribing, then after watching this one, felt it was imperative to add. Great material, keep up the great work.

Those are some magnificent visuals, were helpful for understanding this interesting topic!
