Sun Erupts With Three X-Class Flares in One Day, Complete With Coronal Mass Ejections
The Sun is ramping up towards its peak activity in its 11-year-cycle, and it's doing so in a big way. In one 24-hour period, the Sun has erupted with three progressively more intense X-class solar flares from the same region, each with its own coronal mass ejection.

Though they are able to describe the members of this type of galaxy, they are unable to explain what makes them so red in color.Read on...
