The Sun’s rotation creates a spiral pattern in the solar magnetic field in interplanetary space, known as the Parker spiral. The drag produced by the spiraling magnetic field causes angular momentum to be transferred away from the Sun. This diagram shows the heliospheric current sheet that separates the regions of space where the magnetic field points toward or away from the Sun.
These images, while they appear to be psychedelic art, are actually colorized images of the Mandelbrot set, a mathematical phenomenon. The Mandelbrot set is a pattern of geometric points that repeats within itself (meaning that any image you take of a particular section of the set can be replicated by zooming in or out) and and is infinitely complex; it is what’s known as a fractal. More info, images, and video of the Mandelbrot set can be found here.
In his second year of neuroscience grad school, Greg Dunn was moonlighting with a different kind of experiment: blowing ink across pieces of paper. The neuron-like pattern it formed was instantly recognizable to him as a neuroscientist. “Ink spreads because it wants to go in the direction of less resistance, and that’s probably also the case of when branches grow or neurons grow,” he says. “The reason the technique works really well is because it’s directly related to how neurons are actually behaving.” Dunn calls this the “fractal solution to the universe,” which he sees as the “fundamental beauty of nature.” (via Discover Magazine)
