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.
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.
what did you just call me
I burst out laughing
Turns out a toroid is a common shape
Always has been. 🍩
You're projecting your desires everywhere.
because simpsons did it.
This is the best summary I could come up with:
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.
The original article contains 280 words, the summary contains 150 words. Saved 46%. I'm a bot and I'm open source!
RIP
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?
They probably rotated it to align with the ICRS.
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?
Very probable.
Binary systems are very common.
Stars of the size that end their lifecycle as white dwarfs are also very common.
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.
