Our lemmy messages go through the Mariana Trench along 4000 miles or so long fiber optic cable of 30 000 tons laid at the dark and scary floor of the sea that is like an alien planet to us. (lemm.ee)

Pyramids are fucking kids toys compared to this shit.

By comparison ISS mere 400 kilometres above us. ~1/10 of the length of this gargantuan cable going through unknown

Truly a megastructure rivalling the sci fi tropes

For other enjoyers of deep sea shenanigans, EV Nautilus is a vessel that travels all over the planet to perform deep-sea research with their ROV Hercules.

They live-stream the video from their rover on Youtube and the chat can ask the scientists questions, etc. It's really cool, I've been following them for several years. Sometimes it's hard to catch the streams during the dives, though, as the nature of global time zones usually puts it at an inconvenient time...

They're diving in the Marianas Trench this month, actually, what a coincidence. The expedition just started yesterday! https://nautiluslive.org/cruise/na172

My favorite video from the channel: https://www.youtube.com/watch?v=g5932tMwVVA

Have you been following them for a while? Some of my favorites are about the various whale-fall research they do. The ecology of whale-falls and how it changes over the course of decomposition is just so interesting to me. I actually witnessed one being discovered live on stream back in ~2020, which was really special. During lockdown when I was working from home I had a dedicated computer set up to play the stream 24/7 in my apartment, with the volume turned up, so I'd never miss any action.

Holy hell this is really fascinating! I read quite a lot about deep ocean but somehow never came across whale-falls. It seems like someone will have many nerdy nights soon :p

Bone worms are cool, I could learn about them forever. They have an endosymbiotic bacteria in their roots that secrete acid that dissolves the bone to allow the worm to absorb the collagen, which it digests.

https://en.wikipedia.org/wiki/Osedax

And even though a symbiont plays a critical role in its life cycle, the genus Osedax doesn't appear to be named after Dax from Star Trek DS9 (which was released before the genus Osedax was even discovered and categorized in the early 2000's), as Osedax is latin for "Bone Eater".

Polychaetes in general are just so damn cool. That's the same class that contains the fairly famous Pompeii worm that lives at the deep sea hydrothermal vents.

It’s just so dang cute!

^ And this fella be like: lmao doesn't care

It’s like Martian rover footage but with actual aliens. and btw Fuck mars, it’s overrated desert anyone would just go insane having to look at rusty barren landscape daily. My mars interest have died out long ago and it always was just a dusty shithole backwater planet. All my homies hate mars.

All mars is is a big cope with inability to travel swiftly enough to find better rocks and not care about it anymore. we can’t get to something interesting so we must cope with mars. The only thing worse than mars is the moon but at least it looks nice

It’s an F tier planet on my tier list

[–] enemyofsun@lemmy.blahaj.zone 9 points 7 months ago (1 children)

Filling the rest of your tier list:

  • Mercury: just a rock ball, even some moons are bigger smh (F tier)
  • Venus: nature's biggest prank so far, well played (A tier)
  • Earth: home sweet home, def not biased (S tier)
  • Jupiter: the reason Venus is like this, bad bro (D tier)
  • Saturn: the reason Jupiter didn't mess up Earth too, good bro (S tier)
  • Uranus: literally who? (no tier 'cause I forgot it exists)
  • Neptune: fishin' for 'em moons, nice (B tier)

You get my cat photo as a token of goodwill in this planet rankings argument. It was him who made this post after all but now fallen asleep afterwards on the tablet.

[–] enemyofsun@lemmy.blahaj.zone 4 points 7 months ago

Cute cat! Thanks him for this wonderful post~

Are those cables really running in the trench?
