NASA's Solar Dynamics Observatory (SDO) telescope captured an image of the Sun on October 28 that looks strikingly like a carved pumpkin.
In the photos, the Sun's dark zones and bright active regions merge to form eyes, a nose, and a sly smile that spreads across the star's surface.
But that "smile" is actually a massive coronal hole —an area where the Sun's magnetic field opens up, allowing high-speed solar wind to be thrown into space. NASA predicts that this flow could trigger weak to moderate magnetic storms on Earth on October 28-29. In that case, auroras could be visible even in the southern regions.
