This is a photo I took 13 years ago of Jupiter and 4 of its moons (top). As a reference the image below is the simulated position at that same time.

You ever wonder why the small band of spectrum we can see (called visible light) is special? I mean almost all animals see in light ranges are are somewhere around here. I mean sure some can see a little farther into IR or UV but in general all animals see roughly around this same narrow band of frequencies in an otherwise infinite spectrum... So what is so special?

Its actually a quantum thing. Everything roughly around visible light and higher interacts with material by electrons jumping energy levels. However IR energy is absorbed by the bonds between molecules instead, which is why IR represents heat.

Basically visible light is right where these two modes intersect. Essentially they are the lowest energy part of the spectrum that is still high enough energy to interact primarily through changing energy levels of electrons. Essentially any more energy and it wont really get through the atmosphere as extreme UV is cut off.. any lower and it wouldnt be very effecieient cause most of the energy goes to heating the eye rather than seeing... So its right in that sweet spot.

LOL another bhlock due to an opinion expressed respectfully... man people have some issues if they cant even hold a conversation...

But yea apparently pointing out the terrorism of Israel is appalling **in addition** to the terrorism of the hamas is being a terrorist sympathizer now...

People just make up hyperbolic shit like it doesnt make them look like a fool... sorry it does.

I just released a new version of Fedipage (a static site generator with full ActivityPub support).

Excited, the new version fixes a major bug and adds a few nice new features!
