One of the peaks I've climbed in NH is called Carter Dome. Although the Whites were carved into their present shape by the receding of the glaciers, the origins are volcanic. At 1/6 gravity, these domes on the Moon would be a bit easier...

Excellent presentation! Thank you. Maybe there's a third possibility. Those "domes" DO look like islands, so maybe they are. The domes could be the tops of mountains that existed prior to the surface-leveling lava flood that filled up the lower areas around them. If that were the case, those domes could be windows to to what materials and structure may lie beneath that "sea".

@Dragrath1

To be fair many volcanic islands particularly in the Caribbean the Aleutians or the Indo-pacific are quite literally lava domes which have breached the surface becoming islands so this can go either way. Also for them to be existing islands aka mountains on the Moon prior to the ocean of storms you would still need some mechanism of mountain building the most likely one being impact crater peak rings so even then the material would be quite different from the surrounding underlying topography.

Hot basalt on the moon will remain fluid far longer than on earth - there's little conductive cooling effect and we can see how it flooded into a smooth "sea" of dark rock. It could have settled around older peaks. Alternatively, less dense rocks might have literally floated to the surface. Is the "sea" deep enough for that?

Hi ASTRUM thanks for this video of the moon 🌝 it’s amazing on how it works David 🌝🚀🙏❤️🇬🇧

Yay! FInally Gruithuisen Domes are addressed!

Being a subscriber to the Thea origin of the moon, my thought is this: those silicate deposits are what's left over from Thea's collision with our Early Earth being drawn back out by gravity and the more uniform magma deposits in the lunar mantle.

Thanks!

Research will tell but looking like a good place to dig in to take some advantage of the existing landscape to shield storage as well as work and living space. Food for thought.

I read the title as “drones that shouldn’t be on the moon”, and expected this video to be about an intense but quiet game between countries to which who can send the more powerful drones to the moon to eradicate other drones, and that on the dark side of the moon, unbeknownst to all of us, a war of space and steel was being fought this entire time.

I just noticed something very interesting. At :47 to :49 there's a thin dark shadow on the surface coming into frame from upper right. A little ways before the shadow ends at upper center you can see what looks like a dust cloud from a rockslide crossing the shadow. If you zoom in you can see it clearly. It looks like the orbiter caught this while it was happening. Amazing!

Where do u get all these images from?

I can watch Astrum all day.

What’s somewhat amusing is that these images look no better than images I’ve seen from the 60’s and 70’s.

if anything depending on composition it could be made by the mantle impact convection of the south basin impactor?

Rhyolite (or rhyodacite, etc) domes aren't always subduction related on Earth. They can be produced by mantle plume hotspots under continental lithosphere -- with the silicic magmas being generated, I assume, by some combination of fractional crystalization and crustal contamination. And obviously hotspot-associated (no subduction required) rhyolite magma chambers _can_ be huge -- as in > 1,000 km3 ... see VEI-8 eruptions at the Yellowstone Hotspot.

I think that when the moon was forming and was surely closer to earth, the two planets were so hot and the atmosphere around them was literally boiling them.... The volcanos were simply spewing lava but also melting as they did it... hence the lack of volcanic craters left behind to see today. As the moon cooled ,large dust storms in its thin atmosphere smoothed the surface, eventually creating the moonscape that we see today. My take on it , thanks Alex ! Preon.

If Luna was cleaved off Earth during an extreme collision event, then I would expect a lot of LavaLamp like convolutions of material as it aggregated, and Earth re-aggregated. The Moon could have easily had 100's of millions of years of volcanism of many different (and exotic) types as the materials gradually cooled during aggregation.

I guess the age of the rock is important. From the description given, it sounds like the domes formed very early in the existence of the moon. I was wondering if a massive impactor on the opposite side of the moon could have triggered the unusual formation.

Those lava tubes would be a great place to explore

Hi astrum thanks for this video of how them moon 🌙 works it is a interesting subject and yes I do like 👍 🖼️ I used to do art in my younger years my medium in oils David 🖼️🚀👌❤️🇬🇧👍

My theory: 5:48. The large crater bottom left might be the stem of creation of the two seemingly separate domes. Is it possible that the domes were actually one huge dome initially? If this crater was created at the time of the basalt plane's ongoing formation could the kinetic energy from the basalt plane have hewn the giant extruding mass of silica in two? The source of the silica may have been the meteor that caused the crater. The heat generated and low gravity may have allowed for such a giant dome to form by lava extrusion. Is this plausible to anybody with expertise? I am very much spitballin. Thanks for the video! really nice

Appreciate it if you'd dial back the 'clickbait titles' and photo. Content is good in general.

The mellow soundtrack feels perfect for this video! (What is it? I wanna know!)

I picked up some shares with masterworks a while back.

Could they be the remnants of the central peaks from very ancient impacts where the crater rims have eroded by some reason?

What aboot "dome domes!!!". The ones that seem man-made!!!! Those are the DOMES that really interest ME ‼️

What is that moving or flashing thing @ 3:20 ?

Darn. I was hoping for a video about the discovery of Lunar caverns. They would be lava tubes though.

A possible heat source capable of generating a pool of molten rock may have come from the Aiken Basin impact. Heat from the impact may have created a pool of molten rock deep inside the moon and fracturing from the impact may have created an avenue for the molten material to move toward the surface where a reduction in pressure could cause adiabatic melting (decompression melting). The heat from decompression melting may have helped maintain a low viscosity in the molten material and enabled the molten material to diffract and produce rhyolitic or dacitic lavas.

Background music name?!

Any idea what causes those wide, meandering tracks on the sand (if you pause at 2:21 you see one, trailing from the big shadow to the "n" of "Gruithuisen")? My first guess (and what little I know!) is collapsed lava tunnels. My second is they've got rabbits.

its the fact that the only planets we know of that have moons the size of ours are gas giants and earth. its also a fact that the moon is too large for earths gravity to contain it in a stable orbit. which is why the moon is currently receading further from earth while taking rotational energy from our planet increasing earth rotational period. and in the future if earth still exists at that point the moon will reverse course and crash into our planet.

It could also be a case of spontaneous separation. Things like that can occur in large castings of pretty much any metal alloy if the conditions are not very well controlled. So to me it is not a huge stretch to imagine something like that occuring in molten rock.

I think that after the formation of the moon it briefly (by geological standards) had oceans of water and a thick atmosphere. It wouldn't have lasted long, obviously, because it would be constantly boiling away to space, but there was an awful lot of it. The moon was made of the same material as the earth, and contained water within it, and not just on its surface. When the collision happened that created a separate earth and moon, the same water that we now have here on earth also was there on the early moon. Too much to dissipate all at once. The lava domes on the moon formed during that time, and shortly afterwards, that water fully evaporated, leaving the moon dry as a bone. Probably some of that water that left the moon would have ended up falling back here to earth early on, which is an interesting thought.

@petersvancarek

2 жыл бұрын

I find it highly improbable there was thick atmosphere and oceans. Moon has too low gravity for that. And Moon was extremely hot when it emerged from accretion of the rubble left after Protoearth and Thea collided. That would make even heaviest volatiles leaving such shallow gravity well in less than year. All the while the Moon was molten mass. Any volatiles released from that magma would go directly to outer space.

There's water in the form of ice hiding in permanently shaded areas on the moon left over from all the collisions over the years but given the conditions and size it's a pretty far stretch of the imagination to think the moon ever had oceans or anything close to a 'thick' atmosphere after it initially cooled down post-formation. Maybe for a few months, maybe.

Version 3, a massive impact on the other side of the Moon heated up the interior, and created shock waves, which over time drove high concentrations of silicates (amongst other things) to the area we see them now.

Interesting theories…

As basalt lava cools you start to get 'silica leeching' which makes the magma more silica rich. As note non-tectonic volcanos, like the San Francisco Volcanic field have had highly explosive rhyolitic eruptions. There are even obsidian flows in this volcanic field. It's completely reasonable that during that flood basalt on the moon had some pockets of silica rich magma that became those composite volcanoes.

Is the moon hollow, what happen to the molton core? Why when struck is like a bell?
