The Sun is by far the brightest object in the sky. It is so bright during the day its light drowns nearly everything else in space.

This energy is produced when hydrogen atoms fuse inside the Sun to form helium. The Sun consumes four million tons of hydrogen every second.
Still, it’s so big that our sun has enough fuel to keep shining for another five billion years. The solar energy production is estimated at 386 billion, billion megawatts. So in 15 minutes the sun radiates as much energy as mankind consumes in all forms, for a whole year.
31 years ago, NASA experienced one of the greatest disasters in the history of the space program. The space shuttle Challenger broke apart just 73 seconds into the flight.The disas...
