Are they trying to distort their country's gross domestic product to keep investors happy. Are they trying to claim there are weapons of mass destruction to get their people demanding a war of intervention?

Good point, YN. If I'd have known how much money my oncologist would made off of my cancer treatment, I never would have let her talk me into it. If only I'd had your advice then...

I don't see what this has to do with an astronomy thread.

You're the one who brought it up.

There are lots of large asteroid blasts on the moon and other rocky planets. This is one that has been discussed.

I had not considered the Mare Imbrium to have been originally made by an impact, but it does look circular. After that impact I assume there was a lava flow of some sort.

That is something I haven't considered. The moon has no atmosphere so there is no resistance on entry. In that case there would be no lava flow. The impact crater might generate enough heat to create a lava flow, though. I think this needs a lot of further thought and analysis.

N=R*x f_p x n_e x f_l x f_i x f_c x L

Has this ever been discussed, and is it suitable for this thread?

I don't know what this relationship is meant to represent.

Regarding the lava flow, one would have an impact crater on an active planet. Sometime later the depression of the crater would be filled with lava. https://en.wikipedia.org/wiki/Lunar_mare

This page from the Space website shows Hubble still gathering useful info:

Thanks, Patty.

I have been thinking of all those astronomy-interested who invest in telescopes and equipment. But we have our own moon which can be examined without any aids at all. And it is always there visible to every part of the world. This post looks at one aspect of the moon: http://www.space.com/33491-mysteriou...t-impact.html?.

I didn't notice the Imbrium Sculpture before, but now that I think of Mare Imbrium being the result of a collision it seems obvious.

Now that the probe called Juno is in orbit around Jupiter we are already starting to get more information on that huge planet: http://www.space.com/33551-jupiter-h...-red-spot.html.

So strange the amount of heat from the Great Red Spot. Perhaps vortices above a super-super-super volcano ?, but that wouldn't account for an acoustical component... Can't wait to find out !

Now I know there exist things like gravity and acoustic waves and the upward coupling of the lower and higher atmosphere assuming these explanations are correct.

Yes and this at the start of the Juno Mission!
