kakes, in Any tools out there to simulate planetary orbits in a binary star system?

I’m no expert, and I don’t own the game (though it’s on my list), but have you looked into Space Engine?

Here’s a wiki page on how to set up a binary system using scripts: …fandom.com/…/Binary_star_script_example

You can also just play around with it in-game. Just add a planet or two to the mix and voila!

RagnarokOnline, in How would we know whether there is life on Earth? This bold experiment found out

Wow, such a cool story and a great lesson in choosing to think about things differently. It really makes me want to study Sagan’s life more closely.

rwtwm, in How would we know whether there is life on Earth? This bold experiment found out

That's a great piece. Thanks for sharing.

The fact that most of our signals for extra-terrestrial life are based on life on earth has always made me concerned we'd miss something. This has made me reconsider a little. We would miss life unlike earth's with our approach, but without an analogy like this to draw on, how could we know?

shottymcb, in More JWST observations are finding fewer early massive galaxies

The team used data from the CAnadian NIRISS Unbiased Cluster Survey (CANUCS)

Scientists make the best acronyms.

niktemadur, in There's A New Record For The Fastest Human-Made Object: 394,736 MPH! - The Autopian

For the non-clickers of the link (like myself):
It’s gonna be the Parker Solar Probe, skimming the sun’s atmosphere in ever tighter and faster elipses with each orbit, gaining more and more speed with each pass.

starman2112, in NASA finds water and organics in asteroid sample—possible clues to origin of life

Can’t wait to see headlines confusing “organic” with “biological”

Caboose12000,

can you explain the difference? I genuinely dont know

starman2112,

Sure thing! In chemistry, an organic compound is anything that has carbon in it. Carbon dioxide, for example, is an organic compound. While organic compounds are what life is made of, they don’t necessarily come from life. Biological, in this context, would be something that’s part of a living thing.

If any actual chemists want to correct anything I’ve said wrong or expand on this that would be appreciated

Caboose12000,

thanks for the explanation!

RvTV95XBeo, in There's A New Record For The Fastest Human-Made Object: 394,736 MPH! - The Autopian

Something finally beat the manhole cover we yeeted off the planet in the 50s? Impressive.

Ilovethebomb,

Yeah, but the manhole cover was in atmosphere at the time.

gravitas_deficiency, in There's A New Record For The Fastest Human-Made Object: 394,736 MPH! - The Autopian

This is roughly triple the previous record, fyi

Cruxifux, (edited ) in NASA finds water and organics in asteroid sample—possible clues to origin of life

That’s because asteroids with organics that create life are sent out by the Pathagorath, the screeching glutton that dwells in the blinding. He’s the creature that lives in the center of the galaxy and sends out asteroids to seed worlds with life so that he can devour their souls. You see when we die our souls are eternally digested in his bottomless belly, and without ever increasing nourishment his metabolism would cease to produce the necessary excretions our galaxy needs for time to exist and we would simply blink out of existence. We owe him eternally for our existence as well as our damnation.

DaMonsterKnees,

What kinda panspermian fan fiction is this?

Cruxifux,

We must make sacrifices to the Pathagorath in hopes that he may notice our devotion to him and destroy our souls before they are harvested.

I can get you a bus load of republicans to sacrifice, but they may upset his tummy.

Kata1yst,
@Kata1yst@kbin.social avatar

Souls. They said the Pathagorath needs souls.

Teon,
@Teon@kbin.social avatar

Crap! I forgot to read the fine print.
Yep, there it is... "requires souls..."
Nevermind.

Brazzburry,

And he sent his one true son to teach us about triangles… Again.

btaf45, (edited ) in There's A New Record For The Fastest Human-Made Object: 394,736 MPH! - The Autopian

This is 632 megameters (million meters) per hour. The speed of light is 1.080,000 megameters per hour. So this object is traveling 0.58% of light speed.

edit:

0.058% of light speed. thanx modva

Toylerrr,

Lights fast wth slow down

Modva,

0.058%, but impressive nonetheless.

@kalkulat@lemmy.world avatar

Many hundreds of billions of dollars were paid to haul all of that mass up the gravity well into orbit. And guess who spent all of that money? And guess who’d like to make a LOT MORE money?

Apart from the spent rockets (now sitting at the bottom of Point Nemo) and fuel, most of ISS was clearly expensive and versatile and well-designed. And VERY likely to be worth recycling.

Instead, send a rocket up there to LIFT ISS into a stable parking orbit that won’t decay in thousands of years. By then somebody will have found a use for most of it. If ‘space-faring’ is really the goal, and not just a gimmick to put money into private pockets.

Using it to make a spectacular fireworks show is an ENORMOUS waste. The Egyptians didn’t dynamite the pyramids … a lucrative decision.

They (or someone anyway) did take the gold off 'em, tho.

My bet: a Starship variant. Send it up, refuel it as needed, and you’ve got a metric shit ton of de-orbit push. Starship will have been to the moon by then, it’ll be a proven platform.

Hell, use a fleet and you could reland the ISS if you wanted it back on Earth intact.

ubermeisters,
@ubermeisters@lemmy.world avatar

ISS would not support it’s own weight or even close to it. You would have to basically disassemble the whole thing again for return trips.

smuuthbrane,
@smuuthbrane@sh.itjust.works avatar

Oh I know. It would be expensive, nobody would pay to do it. But the Smithsonian would get one hell of a display if someone did.

Hmmm… private operators’ space stations in low earth orbit. What could go wrong?

ubermeisters, (edited )
@ubermeisters@lemmy.world avatar

Take a look at the world around you and tell me who’s fucked up more historically, private entities or governments? I feel like the answer is governments. I don’t know about yours, but MY government can’t even make up a fucking BUDGET, and you want them doing shit in space? No thanks. Let’s let the people with passion, experience, and the right pay take care of it.

@kalkulat@lemmy.world avatar

Historically, private entities … not even close. Governments are far more open to scrutiny. Entities pay well to keep their fuckups hidden. You have dig into the hundreds of books written about them to learn the documented facts. How many workers did Ford have shot? (Why did Hitler give him a golden award?) Why did the German dye-makers move their factories to New Jersey, then China? Why was noone willing to insure the early nuclear reactors … so the government had to?

Option 1: government does it

  • Government makes plan
  • Government takes bids for contractors to do the work
  • Lowest bidder that can get a senator some decent head at dinner gets the contract
  • Earth shattering kaboom

Option 2: Private Sector does it

  • Several companies See potential business opportunity
  • Companies innovate in an arms race to develop better platforms and technologies
  • Costs for the entire industry go down as a result of innovative solutions coming to market
  • Financial investments from external sources due to increased traction enable faster development and more rigorous testing
  • Earth shattering applause

So why is our healthcare absolute shit?

ubermeisters, (edited )
@ubermeisters@lemmy.world avatar

Because our representatives allow themselves to be purchased. See bullet point 3 above, and try to keep up please

BluJay320,
@BluJay320@lemmy.blahaj.zone avatar

Because privatization (and capitalism in general) opens the door for greedy corporations to squeeze every bit of profit they can out of something. And skirt regulation or oversight in the process

ubermeisters,
@ubermeisters@lemmy.world avatar

because because because because (ad nauseum) - the law allows it. that’s on the government. We can fix that. No, I don’t know how, and if I did, I would be screaming it from the rooftops.

BluJay320,
@BluJay320@lemmy.blahaj.zone avatar

No, it’s on the corporations for doing whatever shitty things they can get away with.

No corporation has the interests of the people in mind. Only their wallets.

ubermeisters,

We’re definitely had a fundamental impasse here

If it’s a shapeshifting alien serial killer, I’m gonna be pissed.

facelessbs, in NASA will reveal what OSIRIS-REx brought back from asteroid Bennu on Wednesday

I do not understand why this is a headline. it has to right?

xradeon,

Just because NASA has to release information doesn’t mean the normal person knows when they are going to do that. It’s nice to know when interesting information is going to come out.

facelessbs,

do they have a set time line on information gained to release?
