Most stream images currently come from [NASA's image database](https://images.nasa.gov/). Essentially, since NASA is a government entity, their photos are public domain and can be used for commercial use as long as it's clear that NASA does not endorse the person using it (NASA does NOT endorse me, by the way).
The original image can be found [here](https://images.nasa.gov/details-iss029e005904) and features the Aurora Australis from the International Space Station.
The full version of my profile image can be found [here](https://images.nasa.gov/details-PIA01318) and is called, "Where Galatic Snakes Live" because in the top left corner there seems to be the outline of a snake.
Some, such as the panel art and emotes, are made by me.
Some of our backgrounds come some [SpookyRahl](https://www.twitch.tv/spookyrahl) as a gift. Please make sure to check out her stream!
