Solar Flare

You are my sunshine
My only sunshine
You make me happy
When skies are grey

Today I'll let a photo do most of the talking. This incredible solar flare on June 7 was ranked as an M2.5, or medium-sized flare, in terms of energy. Remember that the Earth would fit inside a lowercase o in this picture and then imagine what a massive solar flare would be like.

Bottom Line

Civilization is more fragile than we know.
