Space Weather to the Edge of the Solar System - Revisited

This version is a more polished update to Space Weather to the Edge of the Solar System with more focus on the space weather simulation.

This visualization presents a slice of the data through the ecliptic plane, the plane in which the planets of our solar system orbit. Because Pluto is a bit above this plane, the orbit is projected into the ecliptic plane of the data.

Three different variables are presented from the model - temperature, density, and pressure gradient, simultaneously, using the red, green and blue color channels of the color image. The density of the solar wind (green) flowing outward from the sun decreases as it spreads out. The temperature stays roughly constant as the solar wind material spreads through the solar system. We see the Parker spiral imprinted on the outflow from the spinning sun, much like the outflow from a spinning water sprinkler. We also see the strong density gradients (blue) created by coronal mass ejections and other shocks, propagating outward from the sun in the solar wind.

We can observe regions of interesting interactions when the three primary colors of the basic variables combine to enhance the color, represented in the tricolor diagram below. White represents a hot, dense shock, while cyan (blue-green) represents a dense shock (usually visible close to the sun), magenta (purple) represents a hot, low-density shock, while yellow indicates hot and dense material, again usually close to the sun.
