Straight-sided craters on the Moon.

Recommended Posts

I watch a lot of amateur astronomy videos on YT now that i've got into it as a hobby, we all know the Moon is an unlikely partner in space, why it's here (i think there's around five competing theories as to it's appearance in our Solar system), why it has such a low apparent density, why it's the perfect size to eclipse the Sun, transient Lunar phenomenon etc ...

One thing i find hard to explain is the hexagonal craters. A quick search brings up lots of academic resuolts, it's obviously an interesting problem to many serious researchers, how can a normal impact crater go from round to hexagonal ?

There's a reddit discussion :


Sorry, didn't realise links were being actively parsed! That discussion starts with (i didn't read it all) the sub-surface crack theory. I think that can be thrown out immediately since sub-surface cracks don't sporadically form heacgoanl nodes her, there and everywhere !

Three are lots of thjeories, many of them involving mineral deposits, such as Basalt, but deposits that form instantly upon an asteroid impact and organize themselves into multi-kilometre-wide hexagons? It's not The Devil's Causeway !

I know no-one here can know why some of them are hexagonal, none of us has Hubble at our fingetips, but i'd be interested to hear other theories, i've only done a quick bit of searching.

Hexagons in nature are widespread from bees nests,snow flakes,compound eyes to the Giants Causeway.

Brian Cox covered the hexagon shape in one of his shows. I'm sure you'll find it online. Essentially its a shape that works for most things with very little waste/gaps between.

      An image created by the NASA visualisation studio of what a lunar eclipse would look like from the surface of the moon! Pretty cool right? If you want to get a better understanding of what is happening and why, you can checkout this article HERE which goes into the theory behind it all and also shows you what a solar eclipse would look like from the surface of the moon.

      Dear all,
      yesterday evening after doing the sketch of the three-day old moon, we had a wonderful twilight scene with Venus and the Moon over here.
      So I did a pastel sketch how I recalled it afterwards:

      Clear skies!

      Hello all,
      This is my first post on SL, so please correct me if I have started this topic in the wrong place. I am also relatively new to astrophotography, so please ignore my naivety!
      I had some clear skies last week, so decided to do some lunar imaging with my new(ish) ASI224MC. I captured my frames in SharpCap as RAW24 AVI files, stacked in AS!2 and processed in Registax and Photoshop. When i got to sharpening in Photoshop, I noticed a sort of mosaic pattern over the image, which took away from some of the detail, and really ruined the image the more I sharpened. I did a quick search and it turned up with 'debayering'. This is a completely new concept to me and all of my attempts didn't seem to improve the image at all (perhaps I was debayering in the wrong order?). I have attached some images and also my some of my SharpCap settings in case they are of help.  
      CAPTURE ARE: 1304x976
      OUTPUT FORMAT: AVI files (*.avi)
      EXPOSURE: 0.29ms
      GAIN: 282
      Thank you in advance
      Regards, Josh.

      Transparency good, winds light, let's do this. C925 with the 294mc pro ( ir/uv cut filter ) best 30% of 1-2k frames in AS3. Lightly sharpened in registax and processed in photoshop.
      2 panel mosaic

      Plato and Montes Alps


      Montes Apennininus

      2.5x Barlow

      Decided to get some data with the 178 mono and 685nm filter
