The
Sun is 4.5 billion years old and has used up half of the hydrogen in its
core. It will continue to radiate for another 5 billion years, its luminosity
doubling in that time. Then it will run out of hydrogen fuel and will be
forced into radical changes. (above) |

The
three photographs of the total solar eclipse of 1995 Oct 24 were taken
by Fred Espenak of NASA Goddard Space Flight Center from the small town
of Dundlod, India. The eclipse was unique for its low altitude (23 ¡)
and short duration (40 seconds), due to the fact that the Moon was only
1.1% larger than the Sun. |

The
highly rarified region above the chromosphere, called the corona, extends
millions of kilometers into space but is visible only during eclipses (left).
Temperatures in the corona are over 1,000,000 K. |
