Magnetic Flux Ropes Observed Across Cosmic and Human Scales

Researchers at Caltech have discovered a new stable equilibrium state of braided magnetic flux ropes, called a double helix, which applies to structures from solar prominences to nebulae, and developed a mathematical model that accurately describes their behavior across vastly different scales, from laboratory experiments to light-year-sized astrophysical phenomena.
