Voyage to the Sun
The Sun's surface is a turbulent sea of hot gas. Blinding light pours up from below, created a million years earlier at the core of this vast ball of mostly hydrogen and helium. The surface temperature can approach 11,000F (6,100C), hot enough to vaporize anything.

From the Solar Tempest
At any moment, from a solar storm large enough to wallow a hundred Earths, a cataclysmic eruption--a Coronal Mass Ejection--can explode into space at speeds up to 900 miles per second (1,500 km/sec). It can reach Earth in days and ignite an eerie light show in the far northern and southern skies: the aurorae.
