Magnetic avalanches on the sun reveal the hidden engine powering solar flares
A powerful solar flare, which can drive coronal mass ejections that can spark geomagnetic storms on Earth, has been observed to be built from an avalanche of smaller magnetic reconnection events that build up into a singular powerful eruption.
Scientists Captured the Explosive Birth of a Solar Flare on Video
Solar flares are powered by twisted magnetic fields that snap and release obscene amounts of energy. What scientists are just figuring out now is what sparks that snap. They started to learn a little bit more about the origins of this breakage thanks to a perfectly timed observation by the European Space Agency’s Solar Orbiter on September 30, 2024. This was when researchers finally caught a major solar flare in the act of being born. Using the …
Eruptions on the sun also affect us. Understanding them closely can help to predict when outbursts occur. Researchers have observed such an event and have recognized a avalanche-like effect.
The ESA Solar Orbiter probe discovered that a solar eruption is triggered by initially weak disturbances that are rapidly intensifying. A new set of observations made thanks to the complementary work of four instruments of the probe offer the most complete picture ever obtained from a solar eruption. The study is published in Astronomy&Astrophysics. Solar eruptions are powerful explosions that appear on the surface of the Sun. They occur when th…
