Gorgeous time-lapse picture during the 2010 Equinox with the Sun directly overhead. The equatorial location allows the photographer to show both the Northern and Southern Hemispheres of the sky together.

@crazywhenisleep is referencing this gif that alternates between these two images, one in visible light and one in infrared, asking which is the one in infrared:

It’s the second one. 

FUN SIDE NOTE

“infrared” is a wavelength of light just below what humans can see. Red is the color we perceive when we see the longest wavelength we can, and ‘infra’ means ‘below.’ Hence, “infrared”–“below red”

FUN SIDE NOTE 2:

In movies (or maybe in real life?) you’ve probably seen strip clubs depicted as having red lights. This isn’t an accident, and they often use red light; as the wavelength of light gets longer, it is harder and harder for humans to see detail. Further, we can’t see as well in red light since we didn’t evolve to see in such conditions. Thus, red light effectively “covers up” small defects and marks on your skin. 

Strip clubs, and other such places, use that color light because of this. 

Anthropologists were right. 😜

Thou Shalt Not Kill

As a sniper I was not usually the victim of a traumatic event, but the perpetrator of violence and death. My actions in combat would have been more acceptable to me if I could cloak myself in the belief that the whole mission was for a greater good. Instead, I watched as the purpose of the mission slowly unraveled.

The non-propaganda version of what it’s like to be an American sniper.
