NASA’s Solar Dynamics Observatory released breathtaking close-up footage of solar flares, revealing the Sun as a complex network of blazing plasma loops and turbulent magnetic fields. The new video captures dark filaments cutting across bright, twisting arcs as massive bursts of energy erupt and constantly reshape in real time. To appreciate the scale: the Sun spans about 1.39 million kilometres in diameter, roughly 109 times the size of Earth. What may appear as tiny sparks in the footage are a

It’s #SunDay! This week’s (Dec. 12 - 18) space weather report includes: · 2 M-class flares · 2 C-class flares · 27 coronal mass ejections · 0 geomagnetic storms This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity. The Sun was fairly calm this week, though the bright coronal loops on the Sun’s western limb (right edge) at the beginning of the video and eastern limb (left edge) at the end put on a show. Perhaps it’s a good space-themed alternative to a yule log?🪵🔥 |
