Sun’s Flares Revealed as Magnetic Avalanches, Solar Orbiter Finds

ESA’s Solar Orbiter watched an avalanche of smaller magnetic disturbances cascade into a mid‑class solar flare, revealing how energy is released in the sun’s corona through a sequence of reconnection events. The multi‑instrument observations (EUI, SPICE, STIX, PHI) tracked rapid changes over about 40 minutes, with the findings published in Astronomy & Astrophysics. This work advances understanding of flare triggers and could improve forecasting of Earth‑impacting solar activity.

Magnetic Avalanches Trigger Solar Flares, New Solar Orbiter View Reveals

ESA's Solar Orbiter captured high-cadence observations showing solar flares arise from avalanche-like magnetic reconnection: a weak disturbance spawns a cascade of twisted field strands that rapidly reconnect, creating bright ribbons, fast plasma outflows up to ~400 km/s, and continued plasma rain after the flare, implying energy moves from magnetic fields to solar plasma and this avalanche mechanism may be common across flares.

Solar Flare Revealed as Magnetic Avalanche, Not a Single Burst

ESA's Solar Orbiter captured real-time footage showing a solar flare igniting through a rapid cascade of magnetic reconnection events inside a twisted flux rope, producing high-speed plasma rain and energy transfer that redefines flares as magnetic avalanches rather than a single eruption.

Avalanche of magnetic reconnection powers solar flare, Solar Orbiter reveals

ESA's Solar Orbiter captured a large solar flare as a cascade of rapid reconnection events—an avalanche that builds from weak disturbances to a full eruption—producing rain-like plasma blobs and high-energy X-rays; four instruments provided a detailed, multi-instrument view, supporting avalanche models and improving understanding of energy transfer from magnetic fields to plasma and particles, with implications for space weather forecasting.

Solar Orbiter Captures First Images of the Sun's South Pole

NASA/ESA's Solar Orbiter has captured the first images of the Sun's south pole, revealing that both magnetic poles are on the southern side, during a period of solar maximum when magnetic poles reverse. The spacecraft's high-latitude observations, made possible by gravitational assists from Earth and Venus, aim to improve understanding of solar magnetic activity and its impact on Earth, especially during solar storms. This marks a new era in solar science, providing insights into previously unobservable regions of the Sun.
