Ever wondered what the cosmic weather is like, especially around more distant worlds? NASA's happy to help. It recently published a simulation of the Solar System's weather (specifically the Sun's flares, winds and other behaviors) around the time New Horizons swung by Pluto. The color-coded imagery, which reflects the density, pressure and temperature of outgoing plasma, is more than a little hypnotic -- the plasma slowly spirals out, with coronal mass ejections creating shockwaves (the blue you see above) that travel to the farthest reaches of the system.
