| When it became clear that LED technology would mature almost ten years ago, I was predicting that this would happen.

Interesting, the LED street lights where I live have actually reduced light pollution. Maybe there's a difference in the design of the light fixtures where I live compared to LA.

Fixtures are important, unless the illuminated surface is very bright (e.g. snow covered).
One trouble with energy efficient lighting is that very often the advantage is partly exchanged into more light rather than the full energy saving.
Secondly, modern LED's emit a broad spectrum, a much whiter light to improve the colour rendering. Traditional sodium lamps are much more monochromatic and don't wash out stars that much.
Thirdly, our night vision is not that much reduced by red light (sodium lamps, etc), but much more vulnerable to blue light (that of LED's).

Yes, I've noticed that in some places. Fortunately, the street lights where I live don't seem to use that philosophy; they're well-designed and direct the light strictly downward, and aren't brighter than the lights they replaced. I wish that were the case everywhere.

| Regarding my assumption here, the signals of 'KIC 8462852' may have been caused by a Death Star: https://youtu.be/gypAjPp6eps?t=683

| Still thermodynamically impossible. Where's the heat?
At least the Dyson Swarm idea is actually consistent with observations.

| Well, in the meantime, I have anyway a different theory. 
KIC 8462852 itself may be quite young, just in the main sequence.
If there aliens are at work, I think that they are from the nearby red dwarf.
There, the raw materials may become scarce. So they go to the neighboring star and decompose there the planets and asteroids for raw materials. And what the sun obscured, is simply prowling rubble!
Maybe heat radiation would be to detect in such a work.
But perhaps this depends on the technique used.
They would be there in any case over a hundred years at work.
How many centuries or millennia in fact, we can not know!

| I used to have a simple 130/900mm Newton with a simple camera and used eyepiece projection to capture.
The moon shot is build out off 56 zoomed in separate shots stitched together to get 1 shot. The original image is around 12000 pixels because of that Version here is 1600 pixels. Did some work on it to get better contrast and also to get color in (which the moon actually has). The 12000 pixels of the original was perfect for that.
The sunspot GIF was sort of thinking outside the box. Was in 2007 and for 5 days I took one shot of the sunspot. And then I made a sequence of time overlapping shots. Resulting in this morphing sunspot :)

| Oh, and this one was cool to to watch: the Moon revealing Saturn after the covering on 22 may 2007.

| Ok, another share. Video called "Journey to Hyginus". Used another mosaic for this. It's just a video zooming in on an 10000 pixel image but the result was cool. Was used on a big screen at an observatory for educational purposes :)
Best watched in full screen 1080p HD.

| A while ago I heard about white holes. Apparently they are hypothetical reverse black holes. Instead of taking in matter, it spews it out. Unfortunately, they are not possible in our universe, but they are still interesting.
Hello.

They could still be possible, we just haven't found any yet, just like how people thought black holes were just SciFi
