our ball of nuclear fusion

According to NinePlanets.org, “the Sun’s power (about 386 billion billion mega Watts) is produced by nuclear fusion reactions. Each second about 700,000,000 tons of hydrogen are converted to about 695,000,000 tons of helium and 5,000,000 tons (=3.86e33 ergs) of energy in the form of gamma rays. As it travels out toward the surface, the energy is continuously absorbed and re-emitted at lower and lower temperatures so that by the time it reaches the surface, it is primarily visible light.”

And last night, by the time that visible light reached earth, around 7:55 PM PST, it was glowing red and bouncing off of the clouds hovering above the Santa Clarita Valley. Here it is, as seen from a hill above Pamplico Park.
