#BAFact: The amount of energy the Sun emits in one second is enough to run the entire world for almost a million years.
The Sun is pretty freakin' colossal. The energy it emits is nothing short of mind-numbing.
In a single second, it blasts out about 4 x 10^26 Joules of energy - that's 400,000,000,000,000,000,000,000,000 Joules!
I know, a Joule is a weird unit. But we can compare it to how much energy we humans use here on Earth. The world's consumption of energy in 2008 was 4.7 x 10^20 Joules (via Wikipedia: http://en.wikipedia.org/wiki/World_energy_consumption
Dividing the two, we see that in one second
the Sun emits almost a million times as much energy as our whole planet consumes in an entire year
So yeah. The Sun is awesome.[Image: NASA/SDO]
