Level 8

From a friend's telescope and phone camera attachment a few weeks ago. Isn't technology grand? 🙂

I have been seeing more and more of these! Fantastic!

Beautiful photo.

it’s amazing how round the craters are. It seems like a few things would come in at angles and plow furrows.

Maybe most collisions were with asteroids in orbits similar to Earth and the gravity wells of Earth and Moon pull the collision trajectory towards vertical. Looks to me collision debris is often heavier in one direction than in the opposite, which suggests a horizontal component of impact velocity. Moreover, impacts splash, and secondary impacts may tend to have more vertical motion than the initial impact. A simulation might help, because logic often fails trying to understand chaotic systems like this.

@EdEarl

Not a computer simulation; because the computer will obey the math.

What will pieces of stuff do when they strike other stuff?

@yvilletom Create more chaos. Some of the impact energy turns to heat, and the remainder propels the pieces in various directions and velocities.

@EdEarl I will clarify.

What will scaled down pieces of stuff in the laboratory do when they strike other scaled down stuff in the laboratory?

Will the scaled down chaos in the laboratory tell the experimenters anything about the full size chaos on the site?

@yvilletom Generally yes, but specifically, no. Hurricanes are also chaotic. Notice the spaghetti predictions move in the same direction for a day or two, but the further in time they predict (simulate) the less the different predictions agree. The pieces of an impact and lab impact would sort of be alike, but each impact is different from others, as babies are alike, but different.

Posted by starwatcher-alSolar minimum was in 2019 so the sun is ramping up in flares, spots and prominences.

Posted by starwatcher-alI missed the early phases of the eclipse but the clouds mostly left during totality. All in all a great eclipse. Next one is Nov. 8-22

Posted by starwatcher-al Did you know that you can see Venus in the daytime?

Posted by starwatcher-alOne of these days I think that I'll figure out this Nikon.
