No wonder it feels more crowded

[–] 667@lemmy.radio 78 points 2 months ago (2 children)

This helps explain why days seem shorter as we age, the Earth is spinning faster due to the conservation of angular momentum. The days are literally shorter.

[–] sga@piefed.social 11 points 2 months ago (1 children)

fun fact, days have actually been getting longer pretty much since formation of earth (well moon to be correct). reason iirc is that moon is slowly moving away from earth, and this results in some dynamics changing and as a result earth spins slower. like billions of years ago, it was closer to 23 hours.

ps - very rusty memory right now, should have skipped writing instead of half borked fact

[–] oxideseven@lemmy.ca 3 points 2 months ago (1 children)

You're correct. There are more factors involved too, including climate change, since more ice melting means more water as well, moving the mass away from poles to the center to also be affected by the mind pull too.

All the factors end up changing things by about a millisecond per century. The effect is akin to a spinning figure skater having their arms up over their head vs directly out from their body.

Shhh! Don't let Big Clock know that we are on to them.

[–] bottleofchips@lemmy.blahaj.zone 67 points 2 months ago (1 children)

Well that’s what happens when you leave it out in the sun

[–] 87Six@lemmy.zip 8 points 2 months ago (2 children)

No I think it's because it's cold in space

[–] Mac@mander.xyz 6 points 2 months ago
[–] I_am_10_squirrels@beehaw.org 3 points 2 months ago

There was shrinkage!

[–] NullPointerException@lemmy.ca 56 points 2 months ago (2 children)

Good to know it’s still a flat disc

[–] wewbull@feddit.uk 5 points 2 months ago

Amazing how the countries side over it?

[–] Chakravanti@monero.town 2 points 2 months ago

And gravity!!

[–] pineapplelover@lemmy.dbzer0.com 39 points 2 months ago (1 children)

Second picture looks smogier and more polluted

[–] PoopingCough@lemmy.world 44 points 2 months ago* (last edited 2 months ago) (1 children)

Well the second pic is also at night with a high iso and long exposure plus it's digital so there's a lot more noise going on.

[–] IMALlama@lemmy.world 10 points 2 months ago (2 children)

Speaking in generic terms, film is way more forgiving of over exposure and digital is way more forgiving of under exposure. A fast lens is always king, but once you hit parity on that I would personally take digital for low light any day.

By the way, speaking of changed colours of planets: if you haven't been keeping up with the latest news in space imagery and want a real mindbender, check out what has recently happened to Neptune. You may have been thinking, ooooh, what an enthralling blue planet! - bzzzzzt, turns out it's a pretty bland and boring gas giant, the colours were exaggerated on purpose because otherwise you can't see shit.

[–] TheOakTree@lemmy.zip 5 points 2 months ago

I like the pale blue representation, reminds me of blue jade or some old seaglass.

[–] MajorMajormajormajor@lemmy.ca 5 points 2 months ago (1 children)

This truly is the worst timeline. Next, they'll tell us Uranus isn't gassy too.

[–] NigelFrobisher@aussie.zone 4 points 2 months ago

Nah, it is. Just checked.

The maps were correct, New Zealand doesn’t exist.

[–] the_citizen@lemmy.world 24 points 2 months ago

It's getting old, I guess /s

[–] altphoto@lemmy.today 23 points 2 months ago (2 children)

I like how you can see the ring/sphere of atmosphere in the new image.

[–] nosuchanon@lemmy.world 19 points 2 months ago (3 children)

That’s the new smog layer.

[–] razzazzika@lemmy.zip 4 points 2 months ago

To be fair there was a big hole in the ozone in 1970

It's because the Sun is behind it.

[–] NottaLottaOcelot@lemmy.ca 18 points 2 months ago (1 children)

The magnetic poles must be moving substantially. Africa has rotated almost 90 degrees in a few short decades!

The blue Marble was also photographed "upside down." We tend to rotate it because the shape of Africa is apparent and familiar. The new shot is taken further West and I think closer to the planet so not as much of its surface is visible.

[–] bravesilvernest@lemmy.ml 16 points 2 months ago

Also looks much more sickly (yes, its because they pumped up the brightness lol)

[–] Fontasia@feddit.nl 15 points 2 months ago (1 children)

Android post processing vs Apple post processing

[–] DanVctr@sh.itjust.works 3 points 2 months ago

Went back and looked, actually laughed out loud

[–] psud@aussie.zone 10 points 2 months ago (5 children)

Aside from all else, the first image was taken on film lit by daylight, the second was shot on digital at high ISO lit by moonlight with a little sunlight at one edge

Moonlight doesn't have the same colour rendering quality as sunlight

A lot less green, as well.

[–] ivanafterall@lemmy.world 7 points 2 months ago (1 children)

It's cold out there in space.

[–] jaybone@lemmy.zip 6 points 2 months ago

Don’t they know about shrinkage?

[–] resipsaloquitur@lemmy.world 7 points 2 months ago

Big if true.

[–] ParlimentOfDoom@piefed.zip 6 points 2 months ago (5 children)

It's because we're looking at a different side of the planet in the second photo.

Plus, that 2d image makes it look flat, like a penny.

[–] WorldsDumbestMan@lemmy.today 4 points 2 months ago (1 children)

"Ha! I knew the Earth was flat!"

[–] Chakravanti@monero.town 3 points 2 months ago

Knowledge is power!

[–] explodicle@sh.itjust.works 5 points 2 months ago

That's because the internet made the world smaller.

[–] Taleya@aussie.zone 5 points 2 months ago

Completely different landmasses as well!

Kubrick, we're onto you

[–] mavu@discuss.tchncs.de 3 points 2 months ago

continents seem to have moved too.. weird.

[–] polydactyl@lemmy.world 3 points 2 months ago

Jerryyyy, Earth is a planet!

[–] kossa@feddit.org 3 points 2 months ago (2 children)

It's because the Apollo mission photos were obviously faked. How would they have known how small Earth really is, duh!

It‘s like that one planet in SMG.
