Beautiful Universe

Imagine peering deep into the cosmos and discovering what looks like a glowing human brain neatly encased in a transparent skull—floating serenely against the black void. That's the breathtaking "Exposed Cranium" Nebula, officially designated PMR 1 (also known as PN G272.8+01.0), a planetary nebula captured in unprecedented detail by NASA's James Webb Space Telescope (JWST).Released just days ago on February 25, 2026, these mind-bending images combine views from JWST's two powerful infrared instruments: NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument). The result? A cosmic portrait that dramatically enhances the nebula's eerie, brain-like structure—complete with split "hemispheres" divided by a striking dark lane running vertically through the center, evoking the corpus callosum in a real brain.This planetary nebula forms during the dramatic final chapters of a Sun-like star's life. As the aging star exhausts its nuclear fuel, it sheds its outer layers in expanding shells of gas and dust. The exposed, ultra-hot stellar core (the remnant) blasts intense ultraviolet radiation outward, energizing and illuminating the ejected material—causing it to glow vividly. In PMR 1, astronomers see evidence of multiple ejection phases: a whitish, hydrogen-rich outer "bubble" resembling the skull, followed by a more complex, orange-hued inner region of heavier elements, giving the "brain" its textured, convoluted appearance.First glimpsed over a decade ago by NASA's now-retired Spitzer Space Telescope, PMR 1 has remained relatively obscure—until JWST's superior resolution and infrared sensitivity unveiled intricate details never seen before. The dark central lane may trace an outflow from the central star, while differences between NIRCam (which reveals more background stars and galaxies) and MIRI (which highlights dusty material) offer clues about the nebula's composition, mass loss history, and evolutionary stage.Located roughly 5,000 light-years away in the constellation Vela (the Sails), this little-studied object raises intriguing questions: Is the progenitor star massive enough to end its life in a supernova, or will it quietly fade into a dense white dwarf?These hauntingly beautiful images remind us how the deaths of distant stars can sculpt structures that eerily mirror familiar forms here on Earth—proof once again that the universe has a flair for the surreal.

Crazy about this motherfucker.

Going to do my best to keep up with this XD Combined Wire and Mess since it's TECHNICALLY the 2nd for me now-

Powdered Flowers belongs to me and my lil sis @diamondenderm6n

(In case the writing is too hard to read: "I got you little brother. You'll be alright.")

Little rough, but hey, sketches be fun
