Prolonged radio emissions above a sunspot, akin to those auroral emissions previously seen in the polar regions of planets and certain stars, have been detected using the Very Large Array. This detection could potentially provide support for an alternative mechanism for the origin of some stellar radio bursts.

Polarization of decayless kink oscillations of solar coronal loops provide unique information about involved excitation mechanisms and energy supply, but its detection remains elusive. Here, the authors show horizontal and weakly oblique linear polarization of such oscillations, which favors the energy supply by quasi-steady flows.

Physics-informed neural networks allow the construction of state-of-the-art models of magnetic fields in active regions on the Sun in real time, enabling rapid investigation of the source regions for space weather.

A radio interferometric array in China will form a one-kilometre aperture for tracing solar bursts and will help to improve the prediction accuracy of dangerous space-weather events.

The first post-launch science meeting dedicated to the ESA/NASA Solar Orbiter spacecraft met in-person in Belfast nearly two and a half years into the mission, focusing on building new collaborations and rekindling old friendships.

Why the outer regions of the solar atmosphere are much hotter than the underlying surface is a long-standing question. New high-resolution observations revise the role of waves in the energy transfer and offer an insight into the processes at play.

A laboratory experiment has replicated the braided strands of solar coronal loops and shown that the bursting of individual strands produces X-rays. Measurements of these braided strands and the generated X-rays reveal a multi-scale process that could be responsible for the energetic particles and X-rays that accompany solar flares.

The transformations of energy that accompany solar magnetic activity have far-reaching ramifications beyond heliophysics. Understanding the dynamical chain is fundamental to assess habitability and the capacity for life elsewhere.
