Briefings

A team from the University of Sheffield, Indian Institute of Astrophysics, and University of Newcastle Australia identified that solar spicules are not uniform streams but warped, denser plasma sheets resembling pleated drapery. This discovery challenges previous simulation models by introducing a new structural mechanism for solar jets. The research was conducted between 2026-10-22 and 2026-10-23, with findings presented at the 2026 International Conference on Solar Physics.

Key points

• Solar jets called spicules are 6–8 Mm long and take the form of warped, denser plasma sheets like pleated drapery.
• The discovery was led by a postdoctoral research fellow from the University of Newcastle, Australia, and published in 2026.

Context

This finding matters because it explains why solar jets appear to spin in simulations, which was previously a modeling challenge. Understanding the true physical structure of spicules is crucial for accurate solar physics models.

Limitations

Evidence is limited to a single international team's discovery from 2026. The specific simulation parameters used to generate the pleated drapery model are not detailed in the source. The research is a preprint and does not include peer-reviewed validation or long-term observational confirmation.
