Astronomy: Stars, Comets, etc.

Funny I would have guessed the opposite. I guess the Earth protects the near side from everything except huge impacts that make lasting craters, while the far side is always being sandblasted.

Or did Earth's pull mean Lunar tectonic activity died later on the near side?
St.C needs to post a link, but I would wager that the constant sand blasting from strikes is exactly why it's so smooth- relative to the side that faces the earth.

I had it backwards. The far side is rougher, but it’s visually less dramatic. The lava flows on the near side give it the smoother, more dramatic feel.

 
Pic my son took of the northern lights from central New Mexico. BTW, the light dome at the center is Santa Fe.

Super annoyed this morning. I looked at the forecast here and they were calling for overcast and/or cloudy skies at prime viewing time. So I spent the evening in my basement doing some work. Went to bed and never even bothered to look outside. Wake up this morning to posts from people in my area showing off pictures they got of the lights. Tonights forecast is calling for 95-100% cloud cover at the same time. We'll see.

Kid #1 took these in the suburbs. I don't think I've ever seen them be this vivid in the heart of the Twin Cities.

Amazing. Never seen the northern lights. Envious. Are those timed exposures? Are they accentuating reds or is that exactly what is looks like unaided?

Sometimes. Mine were enhanced with a longer exposure (Samsung S23FE) but were almost as brilliant to the naked eye. Fainter northern light photos are generally enhanced with a longer exposure. The more defined pillar photos people post are with a shorter exposure. The longer exposure blurs them.

The colors are the different gasses being disturbed at different elevations. Greens are low level oxygen atoms (Karman line to 120ish miles), reds are oxygen atoms above 120 miles. Blues and purples are nitrogen molecules being battered around the Karman line.
 
I saw them just a couple times growing up, but never thought of them as special (at the time). Now that I moved out of the UP, I've come to appreciate these events more, and gained a new respect for where I grew up. And I absolutely appreciate them (and other nature phenomena) much more as I have gotten older.

A bucket list item would be to see the bright pillars just absolutely dancing all around me in Alaska, Iceland, or Scandinavia.
 
Well, I missed out on the big Tuesday night show but I did manage to get out last night. I will share photos later (I was a little tired when I got home last night). Lights were not as spectacular as folks saw on Tuesday. Couldn't see them with the naked eye but I was able to pick some up with the camera. A few clouds made it less vibrant but glad I decided to take the time and make the drive away from the lights. Got some good green and pinkish colors. It was a bit windy and chilly so I didn't stay super long.
 
Not as vibrant as some others since I was a day late and we had some clouds but still fairly happy with how they came out. These are 2 of my better/favorite ones. Had to attach them instead of just inserting them as apparently they are too large? I had to keep reducing quality to get it so they would show so they aren't quite as crisp here as they really are

I can’t attach the originals (too large) but they are magnificent

Probably the best photo I’ve ever seen in concept and execution
