It's not. It's 2 spheres. But when you look at a diaphanous sphere straight on you can see a brighter thing through it. You can see the pink parts only at the edges because there isn't a brighter mass behind it. And the edges cause more of the material to bunch up making it easier to see.
Mesmerising images of the end stages of a distant star's life have been captured by the James Webb space telescope (JWST).
They show an unprecedented level of detail of a doughnut-like structure of glowing gas known as the Ring Nebula.
Some 2,600 light-years from Earth, the nebula was born from a dying star that expelled its outer layers into space.
"We are witnessing the final chapters of a star's life, a preview of the sun's distant future so to speak, and JWST's observations have opened a new window into understanding these awe-inspiring cosmic events.
The so-called "planetary nebulae" is a misnomer that dates back to the 18th century, when the astronomer William Herschel mistook their curved shapes for those of planets.
It formed when a dying star blasted much of its substance into space, producing a variety of patterns and glowing rings and wispy clouds that seem to ripple outwards.

why the FUCK is everything a doughnut

because the average person doesn't know what a torus is anymore

I don't know what a torus is. But it sure looks flat to me.

Turns out a toroid is a common shape

Is the pictures rotated in such a away to make it look like as viewed from a specific location on earth? Or why is not just the straight picture?
AbouBenAdhem@lemmy.world · 8 pts · 3y
They probably rotated it to align with the ICRS.
Eheran@lemmy.world · 3 pts · 3y
Ah thank you! One of those things that are essentials impossible to Google without prior knowledge.

Wait, what? How probable is a binary star system consisting of White Dwarfes?
Pons_Aelius@kbin.social · 0 pts · 3y
Very probable.
Binary systems are very common.
Stars of the size that end their lifecycle as white dwarfs are also very common.
MonkderZweite@feddit.ch · 1 pts · 3y
But considering how White Dwarfs are born, both being there without one being blown away/sucked up? Didn't know binary White Dwarfs are even possible.
