Oort Cloud, Solar System

Theseus, from 'Blindsight' by Peter Watts. I referenced the official art, but tried to stick to the proportions and description in the book, which include an outer carapace I've never seen anyone depict. Basically an antimatter-catalyzed RAIR which acquires its antiprotons from a giant array near the sun using quantum teleportation (not how that actually works, but an honest misunderstanding). As best I can understand, the ramscoop not only collects but carries hydrogen in its magnetic field, acting as a colossal external propellant tank, and cycling that hydrogen in and out of the reactor as a mix between a Dusty Plasma Radiator and Open-Cycle Cooling For reference: https://www.rifters.com/real/Blindsight.htm https://www.rifters.com/blindsight/theseus.htm# https://www.projectrho.com/public_html/rocket/slowerlight3.php#id--Go_Fast--RAIR

galaxies : The Oort Cloud lies at the very edges of the Solar system. Even the farthest [human-made objects] which are still working, like Voyager 1, Voyager 2 and New Horizons [have not gone] beyond the cloud. Long-period comets, taking centuries to orbit the Sun, provide evidence for the existence of the Oort Cloud. Scientists believe this vast region is the birthplace of these cosmic [travellers].⁠

“ Imagine a massive celestial bubble made of ice and dust surrounding our Solar System. That’s the Oort cloud ❄️🌌⁠ ⁠ 🚀 The Oort Cloud lies at the very edges of the Solar system. It’s so far away that it can’t be seen directly and remains unexplored by spacecraft.⁠ ⁠ 🌠 Long-period comets, taking centuries to orbit the Sun, provide evidence for the existence of the Oort Cloud. Scientists believe this vast region is the birthplace of these cosmic travelers.⁠ ⁠ ☄️ Apart from long-period comets, the Oort cloud may feature asteroids and dwarf planets.⁠ “

I don't know if it's already been said or done, but this scene from "It's Not Your Fault" Good Will Hunting

Is literally Jeff @ Scott after his rescue from the Oort Cloud

Approaching Comet Tsuchinshan-ATLAS

A comet that may be bright enough to see with the unaided eye, yet only found last year, is due to make a close pass (0.47 AU) to the Earth in the coming month.

This beautiful picture taken back in may shows the comet as it passed nearby two spiral galaxies in the night sky, but the huge snow ball, likely from the Oort cloud (unlike the galaxies) had not even been seen until 2023.

The Oort cloud is a vast area of debris, mostly left over from the creation of our solar system, but also often objects picked up along the way, and is the source of most of the comet like objects we spot.

As our Sun moves around the galaxy, the stars around us also do so but on their own orbits, meaning the closest stars today, won't necessarily be so in thousands of years from now, and some stars come MUCH closer than Alpha Centauri is today, meaning they can cause Oort cloud objects to be slung out or inwards.

As these icy objects fall into the solar system, the sun begins to heat them up, leaving a beautiful tail behind them, and then sling shots them back out again. If they survive the journey, they likely now return to fall back in another day.

I wanna do an edit of TAG with that audio that goes like "wait,,, you don't remember what she looks like?" and then have it be like,,, Alan not remembering what Jeff looks like because I rewatched the ending and my heart breaks for the fact that Alan didn't really remember Jeff
