[00:00:00]A giant dark hole can suddenly appear on the surface of the Sun.

[00:00:04]Some are so large they could swallow Earth whole.

[00:00:09]At first, scientists struggled to understand what they were seeing.

[00:00:14]Because the Sun isn't a solid object.

[00:00:17]So how could something burn a hole into a star?

[00:00:20]But the truth turned out to be even stranger. [music] These massive dark regions are called coronal holes, areas where the Sun's magnetic field opens directly into space, allowing enormous streams of solar particles to escape. [music] And when those particles reach Earth, they can trigger powerful solar storms across our planet.
