It is widely thought to be the underlying mechanism behind cosmic events such as solar flares and substorms in Earth's magnetosphere.

Now, researchers from Kyushu University have used high-power lasers to recreate and investigate this puzzling physical phenomenon of magnetic reconnection in a controlled environment. Their results indicate that fast magnetic reconnection is governed by the local physics of the reconnection layer rather than the properties of the surrounding plasma.
