Yeah, that was definitely some clickbait.

I would hazard to say that most major features of the moon created in the last couple billion years have done so in under 10 minutes.

maegul, miesiąc temu w Euclid discovers a stunning Einstein ring

I’m confused about what exactly the ring is in the image or the main image at least. There seems to be an enhanced image in the article that highlights the ring more clearly as an outer edge, which makes sense (I suppose).

But I don’t understand what I’m to make of the top image. It’s the diffuse light part of the ring?

Balthazar, miesiąc temu

You need to zoom in to the center of the bright elliptical. It would have been easier to see without zooming if they’d subtracted off the elliptical.

maegul, miesiąc temu

Ah yes! Thanks! The enhanced image does day “close up” after all! A bit lazy of me!

Very cool though! A zoomed inset in the main image would have helped I think.

Underutilized meme format, honestly. It can apply to almost anything in daily life circa 2025.

Yeah, even for Lemmy this is bad. I hope most of them are semi-facetious?

it’s just standard “haha self harm funi”, it’s so easy to post and reliably gets a few upvotes, so it’s just a kneejerk response to posts like these.

MrTrono, miesiąc temu w Don’t panic, but an asteroid has a 1.9% chance of hitting Earth in 2032

Am I supposed to panic because it’s unlikely to hit? Meanwhile I’m out here wishing for death by meteor.

threelonmusketeers, miesiąc temu

Just in case this comment is not a joke, here’s the WHO page on suicide prevention.

Either way, there are a few billion other people on this planet who would rather not die by meteor, thank you very much.

PhobosAnomaly, miesiąc temu

I mean, if I was going to go out, then getting my shit mixed by a meteor is pretty awesome. I’m sure I’ll make it on to a few Buzzfeed articles over the next ten or twenty years.

All things considered though, it would indeed be nice if it landed somewhere inconsequential like the ocean; the desert; or Florida.

Florida

You jest, but the Kennedy Space Center is in Florida. Putting the world’s busiest spaceport out of commission might put a damper on future asteroid deflection missions…

Eh, they can launch from Vandenburg if it’s that important. (Or, ya know, Guiana or Baikonur or whatever.)

murmelade, miesiąc temu

Hell yeah this would be my choice too on preferred way to die. There’s something beautifully deterministic about it, a random space rock flying around for millions of years and all my lifes choices and circumstances ending up in standing on the exact spot the meteorite ends its journey. Right in my head. Lovely.

What about hitting the Republican National Conference?

Not to be a doomer but most of us will be dead by then I just hope the meteor takes out any lucky oligarchs still alive in a bunker.

Omgpwnies, miesiąc temu

You think “most of us” will be dead in … 7 years? That’s pretty doomer if you ask me.

lordnikon, miesiąc temu

I just read the ipcc reports and if you read those and don’t start a bucket list for the time we have left. I don’t know what to tell you. Trust me I don’t want to be this way I will fight where I can but I’m going to live my life the same time way a terminal patient lives. Cherish the days we got and if I’m wrong I will eat crow happily with a big smile on my face.

llamacoffee, miesiąc temu

Very doomer. Does lemmy have a “remind me in 7 years” bot? 😅

LouNeko, miesiąc temu

Yeah I’ll take one for the team. I go to the point of impact and when it finaly hits, I’m gonna try to punch it back into orbit.

You don’t have to thank me.

Honestly, at this point, there might be enough of us volunteering to bounce that fucker back to Jupiter. A lot of us will be turned into jam but I think it’s worth the sacrifice.

Forever, humanity could only ever conceivably expand so far due to the expansion of the universe, so as far as we know a still insignificant portion of the universe we could colonize.

Until we make some scientific breakthrough which might solve that problem. If there is any possible of course. There is so much we still don’t know.

AbsoluteChicagoDog, miesiąc temu w Don’t panic, but an asteroid has a 1.9% chance of hitting Earth in 2032

Scientists estimate that 2024 YR4 is between 130 to 300 feet (40 and 90 meters) wide, large enough to cause localized devastation near the impact site. The asteroid responsible for the Tunguska event of 1908, which leveled some 500 square miles (1,287 square kilometers) of forest in remote Siberia, was probably about the same size.

So nothing to worry about

Xavienth, miesiąc temu

Sarcasm?

Idk about you but if it levels 1287 km² of forest, I don’t think that would exactly be good news for a populated area. On the upper range, it could be equivalent to a 40 megatonne bomb.

threelonmusketeers, miesiąc temu

Provided it enters in a similarly uninhabited location.
