  1. Thanks for your informative reply … which threw up a few conundrums, delayed my reply(which I’ve had to split in two- following shortly) …. and had me going back to your earlier comments which have flipped my viewpoint slightly … caused a few rewrites and a rethink or two over the last week! Tackling the Messier Affair in this first post … I now see why the consensus is that Messier is East=>West. … with the very low angle trajectory I felt the slight melt/groove could easily have been a Western arrival and a Zone of Avoidance at the Eastern side caused by ‘bounce’ …. but the LH lip is
  2. Hi Barry … firstly thanks for your very comprehensive, interesting and informative answer - and apologies for my delayed reply - (rewrites, a little research + a family issue problem+ distraction that took precedent over this SGL discussion unfortunately). Glad you don’t mind me pitching a few ideas - speculating on what might be creating the fluorescence? Ignore my ramblings below if evidence shows they make no sense! From the scatter patters in the two photos dropped into the discussion May 8th … Tycho looks like an exceptional surface explosion …. blasting fluorescent traces th
  3. I wonder what % of modern day impacts are producing spiked scattering explosions? Here’s a 2013 impact that illuminated for just 1 second in this video report linked to a NASA investigation.
  4. Firstly …. Apologies Barry for the delayed reply … busy week … and needed more time to study the information you presented before throwing the following ideas in the mix. Could some luminous lunar impacts from observation suggest from the very spiky scatter effects -that an explosion has taken place on the surface? - quite nuclear in intensity? …. not just a dull thump, debris flying up in the air and flopping down in the local area? …. I’m getting an uneasy feeling luminescent effects might not be just disturbed terrain minerals … but the result of a combined explosion on t
  5. I feel the plagioclase variations you mentioned earlier in your OP might be giving important information relating to the heat generated on impact .... the mineral composition of the impacter creating a distinctive chemical signature formed by nuclear fusion/fission(?)- then cooling. I like the idea the plagioclase is showing not only the point of first contact ... but also a rather detailed barometric gradation of temperature impact friction across both Messier+ Messier A impact sites .... rather than varying illumination across the image. If you temporarily roll with the idea of tem
  6. Just thought it worth dropping these rather stunning images of Messier and Messier A you mentioned .... http://lroc.sese.asu.edu/posts/1136 Guessing the traces of fluorescence give a further confirmation from which direction the object arrived? .... showing a gradation in temperature melt across the crater?
  7. Thanks for that ... I will check out those impacts you mentioned. Have just been watching the Icelandic, St Vincent and Mount Etna eruptions and am beginning to have doubts if enough water is being produced as a bi-product of volcanic activity ... unless it’s vaporising largely unseen in some types of eruption ... or is wrapped up in some way to keeping pyroclast and other liquified systems flowing. Here’s an interesting eruption I bumped into this morning showing a different pH extreme which I thought might possibly cause a different type of erosion on our Moon. Wheth
  8. Thanks for that mine of information on my conundrum. It’s definitely a theory I can live with! Appreciate you taking the time. Just a quick comment on the above paragraph .... my erosion idea was based around the time most volcanic activity had died down .... when an atmosphere created by volcanic emissions still lingered for millions of years greatly reducing the effects of sublimation we see today. Where winds, like the storms that rip the surface of Mars ... eroded ejected matter into smooth sandy particulates that blew to form the smoothed contours of many rilles. I had more an ide
  9. Seeing as Barry F-G nailed a very decent answer to the plagioclase scattering .... Just a quick comment on a couple of surface ‘oddities’ which caught my eye in the Cloudy Nights link Merlin66 posted? If you scroll to p.4 post #83 .. the OP Easybob95 has dropped in a colour enhanced picture titled ‘An other mosaic’ which shows roughly in the middle a black line I initially thought was an ‘artefact’ on the photo, then got slightly interested thinking it was a ‘cliff edge’?! False alarm - not seismic heave or crust cracking! Thinking aloud ... The b/w image above it suggests
  10. That clarifies things nicely. With that comprehensively answering pretty much all my questions about this plagioclase material ... I was wondering, while you are in the ‘room’ B ... if you have any thoughts on this other meteor/lunar surface weathering observation I am interested in? It’s not on my bucket list of priorities in ‘The Universe Tour’ ... if ever I escape Earth’s atmosphere and get to the Moon ... I’ll be heading here: I’m trying to promote a new school of thought that is open to the possibility meteor strikes near volcanic craters on th
  11. Thanks for that explanation, Barry ... and the tip below flipping through the LROC illumination options. Any idea roughly how long it would take this space weathering to obliterate the bright crater? - Wonder what chemical processes might to going on with lunar weathering? ... Is it solar ray damage coupled with moisture/gas driven out of the lunar rocks+soil ... hanging trapped in a very thin surface atmosphere mixed with dust?
  12. Interesting photos Merlin66 .... Cheers for responding. Wish the minerals on the moon were as coloured as the ones on Earth! - maybe some are and we see the Moon more in shades of black and white from Earth because of atmosphere and refraction? .... I wonder if the gases and liquids trapped in Earth’s atmosphere were chemically responsible for influencing the multispectral qualities of Earth’s minerals? I guess an astro-geologist with a spectral analyser might throw light on the mineral content of the flare impact points on the Moon that interest me. Some seem to display characteristics
  13. Just a quick enquiry ... was strolling the lunar surface on Iroc and bumped into this area of florescence on the lunar surface. Any thoughts anyone? (Co-ordinates at bottom of screenshot if you want to get better definition from original website). Was struggling to see clear heavy impact crater that would account for the wide spread of surface debris? Didn't think it was image flare - not expert on that so could be wrong - but noticed on RHS there appears to be traces of surface debris scatter? It almost seems like someone threw a very low velocity ‘flour bomb’ at the s
  14. Hi ... are you still around on SGL? 
    I’m a recent member who joined last summer.

    I was surprised there isn’t a dedicated SETI section on the Forum?

    In a Search to see discussions on SETI on SGL ...your post about seti@home project popped up ... and I was wondering if that was a group of astronomers interested in research into ETI in our own ‘backyard’ ... so to speak?

    We have a wonderful interesting planet in this part of the Galaxy that appears to attract a lot of visitors .... but most astronomers just seem to want to laugh it off ... and ignore the fact. Sadly, not very open-minded.
    (P.S. I’m Jon, my writing pulls no punches😁, I’m 63, based in the West Midlands, Coseley ... I’m Lincoln born and raised - and visit my elderly mother regularly on Broadway.(virus restrictions permitting!)

    Regards

  15. Good point. Just positing the idea that gravitational lensing could be caused by many things currently invisible to our telescopes ... I gave the Asteroid belt ice objects as an example ... interesting to know how much refraction is out there we can’t see ..... from the gravitational forces generating it’s shape and extent. But there also might be other factors that might be invisible to our science eg: multiverse interferences .... if theoretical physicists have their say?
