The Sun

As we start 2014, most of the country is freezing its collective behind off.  Therefore, to counteract the cold let's look at the sun (not literally of course).  The National Aeronautics and Space Administration (NASA) has a series of pages devoted to the planets of the solar system, including the sun:

Here we can learn fascinating facts such as the sun "makes up 99.8% of the mass of the entire solar system" and its core temperature is "about 15 million degrees Celsius (27 million degrees Fahrenheit)."  There's even a nice gallery of solar images.  If you hold your fingers near enough to your computer monitor you can almost feel the warmth.
