That special time when you finally realize it’s waaay past 3 a.m.

Is this voxel? Is this pixel art? Just digital? It combines them all so I have no idea!

Towers were made in Magicavoxel, sky is pixelated (parts - manually) but used to be a photo, and the wires… my god, they were hellishly hard to do by hand in 3D but I ended up using the model more like perspective reference ¯\_(ツ)_/¯

Oh. And the shrubbery is obviously a brush :0

Eerie airglow over Tibet

The combination of dark skies and cold air over the plateau known as 'the roof of the world' has produced conditions that astronomers refer to as excellent seeing, free of the influence of city lights and variable refraction of incoming light by layers of different temperature air in the atmosphere. The good conditions that result helped reveal a subtle effect, often hard to see from the ground, known as airglow.

They superficially resemble a weak aurora, but unlike their more intense cousins, they are not focussed towards the poles by our planet's magnetic field, and can therefore be seen in good conditions from any latitude on Earth. The two kinds of glow result from excitation of atoms at the borders of our thin airy envelope by solar energy, but aurorae are caused by high energy particles in the solar wind hitting our world, particularly in the huge solar explosions known as coronal mass ejections. Airglow on the other hand is low intensity excitation caused by the higher energy components of ordinary sunlight such as short wave UV and X-rays. The glow occurs as atoms in the atmosphere combine and separate under the influence of the energy, producing a chemistry induced photonic glow.

In this case, a supercell storm on the other side of the Himalayan barrier in Bangladesh created these huge glowing ripples of airglow, that were shaped into these wavy bullseyes by gravity waves of alternating high and low air pressure in the atmosphere.
