Sun Makes Nervous Face with Hole in Its Head (Video)

The sun has been making some anxious faces lately — but you'd be worried, too, if a huge hole had just opened up on your head.

The sun's apparent nervousness crops up in photos captured over the past few days by NASA's Solar Dynamics Observatory (SDO); you can see the gorgeous images compiled into a video here.

Material zooms away from coronal holes as part of the high-speed solar wind, which can cause geomagnetic storms here on Earth. Indeed, particles flowing from a coronal hole last autumn triggered powerful auroral displays, NASA officials said.

But the "mouth" is middling as far as coronal holes go; a much larger one is visible in the new SDO images as well, draped over the top of the solar sphere like a bad toupee.

The human brain searches hard for patterns and meaning in the data it analyzes, which explains why people may see a face in the sun or on Mars, a man in the moon, or Jesus Christ on a piece of toast. This phenomenon, seeing a recognizable shape in a random image, is known as pareidolia.

"The pareidolia is strong today #FaceOfTheSun," astrophysicist Karl Battams, of the U.S. Naval Research Laboratory in Washington, D.C., tweeted today (July 14), along with a photo of the "anxious" sun.

The $800 million SDO mission launched in February 2010. The spacecraft's high-definition photos are helping researchers better understand the sun's magnetic field and solar activity, including how and why that activity varies over time.
