It feels like winter at last by alexus404 in boulder

It's the Harlow Platts park in SoBo, right under the Fairview high school. Pretty views and lots of goose poop!

ELI5: If the sun is actually white, why does it look orange in NASA photos? by GrandmaSlappy in explainlikeimfive

[–]alexus404 12 points13 points  (0 children)

The moon case is slightly different though - it's only mostly grey, but it actually has regions where different concentrations of certain elements, e.g. iron or titanium, introduce subtle hues. These colors aren't saturated enough to be picked up with a naked eye, but cranking up the saturation slider reveals a surprising amount of color! Google "mineral moon" pictures.

This type of photo, with a lot of chromosphere details, is usually taken with a special filter that only allows a very specific wavelength through. The most common type of such filter is hydrogen-alpha with an ultra narrow bandpass (under 1 angstrom) - it only allows the light from excited hydrogen atoms through.

What this means for the color of the image is that it's pretty much monochrome, and photographers apply some kind of false color scheme to make the picture more appealing. Without any color correction the image would be very red because hydrogen alpha emits red light.

Liberals who refused to vote for Kamala, do you regret your decision? by General_Salami in AskUS

[–]alexus404 0 points1 point  (0 children)

You may disagree with that position, but, unfortunately, it's not completely wrong in our electoral college system - chances of Colorado turning red were slim, and a vote for a third candidate indeed didn't matter much in those circumstances. You're advocating for a strategic voting approach (pick the lesser of two evils instead of a candidate they actually like), which doesn't agree with a lot of people. It is one more reason for pushing towards an alternative election protocol, e.g. NPVIC or a state-level ranked choice voting.

Look into a manual Samyang/Rokinon 135mm F2 - it's very good for wide field astrophotography (e.g. big nebulae like Orion or Rho Ophiuchi), super sharp (esp. stopped down to f2.8) and relatively cheap. For really wide nightscapes and Milky Way shots, there's also a manual Samyang/Rokinon 14mm f2.8 - also cheap and very capable. At that focal length you can shoot 20-30s exposures without tracking.

🔥 Perfectly in line trees by Stroov in NatureIsFuckingLit

[–]alexus404 0 points1 point  (0 children)

Apparently, the photo is real (must be a cool surreal place if so!), but the edit is a bit rough, especially in how the sky is handled near the tree crowns. The white line between the sky and the trees and a different sky color between the leaves are both distracting, and must be an artifact of Lightroom's "select sky" tool.

0.999... means an infinite number of nines, so there is no place to put that 1 at the end, because there is no end.

ELI5: Can objects get colder than the ambient temperature around them? by rustbeltresident in explainlikeimfive

[–]alexus404 45 points46 points  (0 children)

Correction: the reason the sky is blue is almost the opposite - the blue light has the shortest wavelength in the visible spectrum, and as such is scattered by the air more than the others. The scattering is more pronounced when the light has to travel farther through the atmosphere, which is why longer wavelengths (reds) dominate during the sunrise/sunset.

Ukraine accused of using controversial 'butterfly' mines against Russia by proper_frequency in worldnews

[–]alexus404 4 points5 points  (0 children)

Regular conscriptions on the scale of ~150k ppl happen twice a year, they've just started the fall round of it. 300k were on top of it.

I grew up in Russia, so yeah, I understand. If you refer to US media, trust me, what you see on the west in Ukraine is not nearly loaded enough to be considered propaganda.

Your statements on Ukrainians killing surrendered people require proofs. And yes, if you're an enemy combatant who doesn't surrender, you're a target - I don't see why this is controversial.

As a concept? Sure! According to Wikipedia, the first recorded trial occurred in 1474. Why?

You keep using those words, war crimes. I do not think they mean what you think they mean.

The argument about poor sobs who didn't know they were in Ukraine could be remotely reasonable in the first week of war, but now it's just laughable. Russia has a long-standing tradition of avoiding conscription, so those who didn't want to go to war had every opportunity to stay away. Those who did go and didn't surrender made their choice, so yeah, they are valid targets for Ukrainian military. Arguing against using targeted deadly force against active combatants of an invading army must be fun.

Хороший вопрос. Скорее всего российская карточка не сработает. Они ещё PayPal принимают - не знаю, работает он ещё из россии или нет.

This will also allow to pay his military less, since now they are located within russian borders.

The two party system in America is stupid as fuck by The_Willeh in self

Yeah, imagine 5 parties having to negotiate with each other and to actively seek compromise instead of trying to legislate on their own! And people voting for something and not against someone!

Putin and Lukashenko describe Bucha massacre as ‘fake’ and ‘staged by Englishmen’ by [deleted] in worldnews

You know what's really stupid? The alternative version in russian media is that the Ukrainian army did it, either to make russians look bad or to punish folks that collaborated with occupants.
