Story summary

Caltech researchers identified a stable double helix state in plasma flux ropes, linked to cosmic structures like the Double Helix Nebula.
Led by Paul Bellan and Yang Zhang, the study examined the Sun's corona, characterized by high temperatures and strong magnetic fields.
They developed miniature solar flare models in a vacuum chamber, showcasing self-stabilizing braided plasma structures.
Zhang's mathematical model predicted behaviors of these structures, including those in the distant Double Helix Nebula.
The research demonstrates that magnetohydrodynamics connects lab experiments with astrophysical phenomena, challenging prior assumptions about braided flux ropes.
