It’s just a space snake, chill tf out

HootinNHollerin,

Where’s Samuel L Jackson when you need him

Denalduh,

He’s busy pressing the snake button on the microwave.

JoMomma, w I want to be among those who deeply thoroughly understand & can accurately predict the path of future eclipses because this is amazing.

I’m pretty sure they just hold up a tennis ball and shine a flashlight on a globe, its not rocket surgery

dudinax,

I’ve heard from a government authority that the eclipse path is determined by how gay we are.

LemmyKnowsBest,

I like the way you think

JoMomma,

You’d be the first

LemmyKnowsBest,

SpeedLimit55, w Big, doomed satellite seen from space as it tumbles towards a fiery reentry on Feb. 21 (photos)

Satellite or Tie Fighter?

ShittyBeatlesFCPres, w Map reveals all the space junk we've already littered on Mars

Opportunity spent 15 years roving its ass off for this planet and now we have the nerve to call it “Space Junk.” No respect.

XeroxCool,

It proved it’s ass off because it thought maybe, just maybe, if It analyzed one more good rock, we’d let it come home since it’s original mission was only supposed to be 30 days.

WarmSoda,

Evaaaa!
Wallll-eeeee!

Boeing technicians: “Amateurs!”

jumperalex,

woah too soon man, too soon

naw, just perfect!!!

FiniteBanjo, w OP: "This is my most advance moon photograph EVER it consist of 81000 images and over 708GB of data." (see comments.)

I don’t know anything about moon pictures, my best attempt was not great

https://lemmy.today/pictrs/image/dc85d2fb-df81-4245-bb2c-33d001571e43.jpeg

But how did they composite 81,000 images without worrying about atmospheric lensing distorting the proportions as it moved across the sky for 4 days? Is it just negligible?

Good question.

friend_of_satan,

Is that just the Samsung smart camera composite?

FiniteBanjo,

Huh? Nah it’s an old Canon 1300D. I had to hold the tripod still with sandbags while it took.

friend_of_satan,

My comment was mostly sarcasm. theverge.com/…/samsung-fake-moon-photos-ai-galaxy…

Cool that you used a “real” camera to do it. Just the experience of doing that is satisfying even if the photos don’t come out great.

And009,

Then we appreciate the Nasa images more

Liz,

The Samsung moon actually just makes up a plausible looking moon, which is hilarious given that the moon essentially doesn’t change, so they could have just overlayed reference images. Instead, you get features on the moon that don’t exist.

Kichae,

They didn’t. What they did was take 81,000 images and then filter through, them taking the best images of each region of the Moon and then averaging and compositing those.

It isn’t 81k images stitched together. It’s 81k images taken in the hopes of getting enough with perfect clarity to create the composite.

TropicalDingdong, w NASA Finally Removes Last Two Fasteners To Access Historic Bennu Asteroid Sample

NGL, I’ve given up on projects when I can’t get a fastener undone.

I’m glad they stuck with it.

@Rhaedas@kbin.social avatar

Obviously NASA engineers don't ever go to Youtube, I'm sure looking up "asteroid sampler stuck" there would have been a number of hack DIYers who showed a variety of techniques they've used.

TropicalDingdong,

Missed opportunity for a NASA first time unboxing video.

Tschssss nice hiss, strong smell of alien symbiote. Let’s put some out on the tray here and give it a taste”

UlyssesT, w Elon Musk destroys astronomy

Some of Musk’s bootlickers have said to me, offline in person, that the le epic Starlink debris in space fucking with astronomy (as it has for a while now) “will only encourage the exodus off planet” followed by the PR spiel about “humans must become interplanetary species.”

May as well say that the cradle must be burned with the baby in it so the baby is encouraged to compete in Olympic track and field.

100_kg_90_de_belin,

All those sci-fi movies about human beings acting as an interplanetary infection only to find retribution at the hands (paws? Claws? Appendages) of an eldritch creature taught us nothing 😔

ekZepp, w Scientist performs the first nonlinear study of black hole mimickers
@ekZepp@lemmy.world avatar

A nonlinear study refers to an approach that does not follow a straight, sequential path in analyzing or modeling phenomena. Instead, it allows for complex relationships where changes in one variable do not directly correspond to changes in another, often leading to unpredictable outcomes. In the article, a Princeton scientist explored the nonlinear dynamics of boson stars, a type of black hole mimicker. His research revealed unique gravitational wave signals during mergers, distinct from those of traditional black holes, which could aid in identifying these mimickers in future gravitational wave observation

And we found the MVP. Cheers to you, mate, and your explanation, thanks!

Lookorex,

I would also like to thank you for that

julianh, w Voyager 1 is fully back online months after it stopped making sense.

It’s insane what these people do. They’re rewriting code from the 60s to use even less memory, have to test it in production without physical access, and it takes two days to see if anything changes. It’s an insane piece of engineering and it’s incredible that it’s still sending useful data.

Serinus,

I’d love to see what their test environments are like. You can’t test everything, but they can certainly test some things. A raspberry pi has more software capability.

magikmw,

They have a second probe in the shop to test. Thankfully.

Sequentialsilence, w NASA loses contact with Ingenuity Mars helicopter

So basically 72 flights into it’s 5 flight mission it went to far over the horizon and lost line of sight. So they have to drive over to it to re-establish communication.

  1. They’ve done good already, they don’t need to go this hard.
  2. They went so hard they went over the horizon and lost coms.
  3. Because it’s autonomous it’s likely still operational, they just have to get close to it.
WalnutLum, w Elon Musk destroys astronomy

Looking forward to when Europe and China also launch their own satellite internet constellations

AlligatorBlizzard,

Loved that manga, I should re-read it and try watching the show again.

kinttach, w Caltech Researchers Find Evidence of a Real Ninth Planet

This is an old article. It references the Batygin and Brown paper from 2016. As of 2024, it is still considered possible, but no direct evidence has been observed, and alternative explanations have been proposed, according to Wikipedia.

vzq,

Things are looking pretty grim for planet nine, it’s running out of places to hide. It was a cool hypothesis and a gutsy prediction, but I’m afraid that it’s not going to work out.

ShittyBeatlesFCPres,

Won’t the Vera Rubin Telescope (formerly LSST) settle this? It’s going to observe the entire night sky every few nights and provide enough data to find nearby moving objects.

MachineFab812,

This paper seems to be dated 18 April, 2024. Wouldn’t surprise me if its some sort of re-print, but otherwise would explain why this topic popped up in the media over the last few days. arxiv.org/pdf/2404.11594.pdf

expatriado, w Tiny glass beads suggest the moon had active volcanoes when dinosaurs roamed Earth

so, 96% of its life, and we just missed it

UnderpantsWeevil, w Size Comparison: Pluto and Australia
@UnderpantsWeevil@lemmy.world avatar

First they came for Pluto’s planethood.

Next they’re coming for Australia’s continenthood.

lugal,

When they came for Pluto, I said nothing because I wasn’t a planet
When they came for Australia, I said nothing because I wasn’t a continent
When they came for Bielefeld, I said nothing because I wasn’t a city
When they came for me, there was no one left to say anything
