It was Marvin, with a Deutonium Q-38 Space Modulator, from ACME. (obstructing his view of Venus)

that's what they want you to believe, they still haven't shown us the monolith

“About 3.8 billion years ago” in case the title has you freaked.

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.

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?

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.

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.

Is there any way to get it here sooner?

Fucking finally goddamn

Reading this headline instantly brought a huge smile to my face 😁

Can we speed that up a bit?

Wow this is the most depressing comment section I’ve ever seen.

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.

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.

Provided it enters in a similarly uninhabited location.

Majorllama, 4 miesiące temu w Don’t panic, but an asteroid has a 1.9% chance of hitting Earth in 2032

Which direction do I need to fart to up those numbers?

Uranus_Hz, 4 miesiące temu w Don’t panic, but an asteroid has a 1.9% chance of hitting Earth in 2032

Those are rookie numbers. Gotta pump those numbers up.
