Supernovas will never cease to puzzle us. That's the best thing about them.

Nice work, Anton.

This is fascinating. The universe seems endlessly willing to supply us with weirdness. I greatly appreciate your telling about some of it. 🙏🏼

[jimcurtis]

Wonderful as always Anton. Thank you. 🤘😎

Textbooks always make stars sound so steady and predictable and it turns out in real life they just do whatever they want.

[Alondro]

It probably crossed the stable mass threshold and partially collapsed, which triggered the carbon burn. But, it's already so small and dense that this carbon burn is going at a radically accelerated rate. It's probably also fusing other elements swiftly as well and producing all manner of odd isotopes due to the electron-degenerate matter making up the original white dwarfs. Portions of its core might even be being forced into neutron-degenerate matter by the extreme pressure and density, as this is a star that SHOULD be collapsing into a neutron star by its sheer mass alone.

I want take time to appreciate how anton has yet to appear to sell out to the typical youtube marketing giants that have destroyed channels left and right and he remains a wonderful and perfect content creator

Ain't nothing normal in space anywhere . . .

4:00 Now that's what I always thought a supernova should look like- a big firework going boom!

[richardzeitz]

This is the intriguing exotic star ever reported on by you or any other science YouTuber I follow. Thank you! I just opened the Astrophysical Journal article you provided a link to. This reminds me I need to renew my subscriptions to Nature and Science. Incredible!

ObiWan Petrov: this is the supernova we've been looking for.😊

[johnburnside]

"These aren't the supernova remnants you're looking for..."

[yomogami]

awesome! i love when we find things that confound the worldview to help expand our knowledge
thanks anton

[rbsr]

The possibility of it going supernova in our lifetime is beyond thrilling!

[loganskiwyse]

A new category of star might be some of the most exciting news this year.

[walterfristoe]

I love it when we come across a mystery, because it means we'll eventually learn something new!

[markgoode]

Always so interesting. Thankyou wonderful person.

[augustwest]

"Bizarre object we've never seen", seems to be JWSTs middle name.

[Aristoteles]

Wow, this thing is gigacool! So, you basically have a Wolf-Rayet like stage of a White Dwarf produced by a rare kind of stellar merging. Making it the hottest and rarest star in the entire galaxy! I love it!

[kamuroshow]

Wow. This is huge news. Thank you anton for sharing. I remember myself asking for posters from nasa by actually writing a real handwritten letter to them. And they send me some. Look where we are now. ❤

Great upload Mr Petrov, enjoyed it.
When it comes to some stars, densities and sizes must surely vary, it's like no two stars are exactly the same, similar perhaps, but every circumstance is inherently different to the next. Good job sir.
