We have a link to a 7-second video, recorded by extreme UV cameras onboard the Solar Dynamics Observatory. It shows an enormous magnetic filament breaking away from the sun. Some of this breakaway material is now en route to Earth in the form of a coronal mass ejection (CME). Click on this link to view.

As we noted yesterday, this "solar wind" may result in auroras, or an opportunity to view the Northern Lights from higher latitudes. Be on the lookout starting early tomorrow morning!

The Sun has constant nuclear explosions at its core, underneath the sea of boiling gases that form its surface. You can read more about the star at the center of our solar system in my book of the same name.
