COMIC - Cosmic Mysteries: Black Holes

(Heliosphere: Under the Sky is an original solar system project with personified stars and planets)

Space facts!

Black holes are mysterious. They are huge concentrations of matter packed into very tiny spaces.

A black hole is so dense that gravity just beneath its surface, the event horizon, is strong enough that nothing - not even light - can escape.

Black holes can be stellar or supermassive.

However, continued studies propose intermediate (middle ground mass), primordial (formed with the universe), and ultramassive (in the case of TON 618).

Tidally Locked

Commission for @foxgirlchorix of two moons of her giant planet Kizudea:

Kolayut, the homeworld of the catgirls

Astharulo, the homeworld of the foxgirls

also, Taruvidi, a large as-yet uninhabited satellite planet.

On the right, we orbit Kolayut and can see Astharulo and Taruvidi behind Kizudea. On the left, we orbit Astharulo and can see Taruvidi in front of Kizudea and Kolayut behind it.

See also, Beneath Shared Skies by @thefallencomet; inspired by Tidally Locked Catgirls by @twinicegiantorbiters

After a look into the recent past (50-100 years ago) with the last illustration, let's look back further.

In the geteza homeworld's ancient seas, the mostly sessile Zoophytes share a sea-dwelling ancestor with the mostly motile creatures of the planet. All Zoophytes, sessile or not, have a mutually beneficial relationship with photosynthetic red algae-like organisms. In sessile Zoophytes, these microbes are responsible for creating most of the creature's energy. Paedomorphic Zoophytes, on the other hand, are consumers and get their energy from eating other organisms, with the red microbes supplementing their energy levels.

Cultures of these microbes are passed down from parent to offspring, leading to many different strains.

Most sessile Zoophytes will only exchange gametes during their motile, reproductive phase, with different courtship rituals dependent on species, using the stored genetic material for use only once it has fully metamorphosed.

If we ever do discover life on other planets, I doubt the life will be happy that we found it. -- Michael Lipsey

looking at hubble images and galaxies is terrifying bc there's literally billions of stars. at least two planets in our solar system alone have and have had life in some capacity. it's nauseating to know that looking at a galaxy is not only looking however many years in the past but it's looking however many planets with life on them. just imagining the planets in all those solar systems. in solar systems with suns larger than our entire solar system.

#i always wonder if a larger star means they'd have larger planets.#and not just mega gas giants #i mean like terrestrial planets #or would they have hundreds of averaged sized planets.#is their habitable zone bigger than a smaller stars? or is it smaller?

hard to feel enthused about space news anymore when every other kind of news is so bad

#jwst found atmosphere around a terrestrial planet #but i can't find it in me to be excited about potential aliens with...everything else going on in the world #with the election coming up in particular bc i know what the outcome is going to be and i know things are going to get much worse #emilio.txt

Coming up with specifics that I Do Not Need for a verse in such a way that I spend hours upon hours upon hours researching for it, otherwise known as Chris' HSR verse!Nikolai Adventures

#muse: nikolai gogol.#Figured I should settle on a planet for Nikolai's HSR verse even tho a) it's not 100% necessary; and b) I could've just winged it #and so I ended up researching this solar system and the next one (I mean it.) and eventually settled on planet Boinayel (WASP-6b)#Why you might ask. The vibes I may answer. ADGHSAJDSAK I'm thinking about how we only say that a planet is habitable if it is for /us/#but imo that shouldn't mean it doesn't have intelligent life of its own. Plus to keep Nikolai's planet similar-ish to BSD's world #I figured the civilization there could keep BSD's quirk of having Abilities; except /everyone/ (in this HSR verse) has them #that's how the civilization on Boinayel survived on what to a terrestrial lifeform would look like an utterly inhospitable planet #I have plenty of ideas for the planet itself too. And its inhabitants. And Nikolai's story there. And-

Quick and Easy Worldbuilding

Decided the other night I'd make a terrestrial planet with oceans, an ice cap, and some continents.

First, I drew a shitty little map in Krita...

Then I made a sphere in Blender...

Slapped the map onto the sphere as an image texture, then made some smaller spheres for moons...

Went to the Render dropdown and selected the Image option...

...and Voila!

Evolution Rant

Water/land & water/air animals should very clearly only be water animals. Where did evolution get its wires crossed? Did the meteor fuck shit up that bad?

Walruses, seals, whales, elephant seals, sea lions, sea turtles. Etc. Look at them its unnatural that they be on land.

If the animals only mode of transporting itself around on land is scraping its body against the ground and pushing with flippers, then it is clearly only meant to be in the water. Get back in there.

Watching walruses fight is so unsettling. They have to work so hard to get leverage. The rocking back and forth takes so much energy that is not even a fight is who gets tired the slowest. How is that fair? Then they have tusks, I'm always scared they're going to get stuck or ripped out, and then Wally is dead because it can't hunt or defend itself. The Wally 2 will die of an infection.

Whales! What do you mean whales have to breach every hour, give or take, to breathe air!?!? That's insane. They live in the water. They should have gills. Sharks have gills. Why don't whales?

Watch a video of a seal in the water. It's beautiful it's sleek and graceful. As soon as it's on land, it's a waddling blob dragging itself against the coarse sand and sharp rocks.
