The sun is a constant presence for all life on Earth, bringing light, warmth and splitting our days and nights. But the sun is more than just a bright light in the sky and a new NASA video reveals its ever-changing surface in a stunning time-lapse that spans 133 days. Astronomers have discovered that one of the most important magnetic effect at work on the sun is the same one that fastens your cell phone's magnetic flip cover. But on the sun, the result is much more dramatic: Twisted magnetic fields carrying streams of hot charged plasma become entwined, then snap and rapidly reorganize. That so-called fast magnetic reconnection releases huge quantities of energy, and Earth is often subject to the accompanying flares, plasma bursts and geomagnetic storms.

But exactly why fast reconnection happens, and why it releases energy at a constant, predictable speed, has been a mystery for 60 years. Now, observations by NASA's Magnetospheric Multiscale Mission (MMS), a quartet of small spacecraft flying around Earth in a pyramidal formation, may have helped uncover the answer.
