Satirical title, not the real story.

A Japanese spacecraft has spotted two huge holes in the sun -- gateways for solar material and gas to spill out into space.

Scientists call the sun holes "coronal holes." They are gaps in the sun's magnetic field which make a hole through the star's super-hot outer atmosphere -- the corona -- allowing gas to escape, according to a NASA description.

Japan's Hinode sun-watching satellite photographed the sun's two coronal holes on Feb. 1. In the image, one coronal hole appears near the top center of the sun while another one -- a polar coronal hole -- is visible near the bottom of the view.

The holes appear darker than other parts of the sun, but there's a reason for that.

"The holes are relatively cool in temperature as compared to the active regions nearby -- such as the bright region on the lower left portion of the solar disk -- the cooler temperature is one of the reasons for the darker appearance," NASA officials said in a statement.
