What is aSolar Eclipse?
A solar eclipse occurs when a new
moon passes between Earth and the
Sun. If the moons shadow falls upon
Earths surface at the time, you will
see some portion of the Suns disk
covered, or eclipsed by the moon. A
new moon occurs every 29 days,
but an eclipse only happens when the
moons orbit is tilted 5 degrees to the
Earths orbit around the sun. There
are three types of eclipses: partial,
total, and annular. Usually, the
shadow misses Earth as it passes,
making eclipses rare. Evidence shows
that ancient China and Babylonia
were the first to have records of solar
eclipses.
PENUMBRA AND UMBRA
There are two parts of an eclipse. The
penumbra is the moons faint outershadow. When apartial solar eclipse
occurs, it is only visible from within
the penumbral shadow. The umbra is
the moons dark inner shadow. When
atotal solar eclipse occurs, it is
visible from within the umbral
shadow.
See below for diagram.
The last solar eclipse occurred on
January 15, 2010, and was an
annular eclipse. This was visiblefrom central Africa, the Indian
Ocean, and eastern Asia. A partial
eclipse was seen from eastern
Europe, most of Africa, Asia, and
Indonesia. On July 11, 2010, the
next total solar eclipse will occur.
The umbral shadow will cross the
South Pacific Ocean where it will be
visible from only the Cook Islands,Easter Island, and other isolated
places. A partial eclipse will be
visible in the South Pacific and
southern South America. Also, two
lunar eclipses, a partial and a total,
will occur in 2010.
Past and Future
Path of Totality- The track of the
moons umbral shadow across Earth is calledthe Path of Totality. This is 10,000 miles long,
but only 100 miles wide, and covers less
than 1% of Earths entire surface. In order
to see a total solar eclipse, you must be
somewhere inside the small Path of Totality.
This path can cross any part of the Earth,
but is very rare to see in one single
location. A total solar eclipse is very brief
and only lasts a few minutes, and when it
does, the sky takes on an eerie twilight.
CORONA- The white halo surrounding the
sun during an eclipse is called the solar corona.
Its a super heated plasma that reaches 2
million degrees. This corona can only be seen
a few minutes total solar eclipses.

Three Types- The tree types of eclipses
are partial, total, and annular. A total solar
eclipse occurs when the moon passes
between the sun and the Earth, and the
moon fully covers the sun when it is viewed
from some part on Earth. In a partial total
eclipse, the moon only partially covers the
sun. An annular eclipse occurs when only a
small sliver of light is seen from the suns
disk.
