Lunar and Solar Eclipse Events: A Total
Lunar Eclipse is an eclipse of the Moon
where Earth crosses between the Sun and
Moon, blocking sunlight from reaching
any of the Moon's surface. During a total
eclipse, the Moon darkens slightly and
takes on a reddish colour.
A Partial Lunar Eclipse is an eclipse of
the Moon where Earth crosses between the
Sun and Moon, blocking sunlight from
reaching only part of the Moon's surface.
This part will appear darker than the rest
of the Moon.
A Penumbral Solar Eclipse is an eclipse of
the Moon where Earth crosses between the
Sun and Moon, but only partially blocks
the Sun's light. Because some light still
reaches all parts of the Moon, the Moon
does not darken noticeably during a
penumbral eclipse.
A Partial Solar Eclipse is an eclipse of the
Sun where the Moon covers only part of
the Sun. The sky does not darken
noticeably during a partial eclipse.
A Total Solar Eclipse is an eclipse of the
Sun where the Moon completely covers
the Sun.
An Annular Solar Eclipse is an eclipse of
the Sun where the Moon passes directly in
front of the Sun, but does not completely
cover it. At the eclipse's peak, a ring of
sunlight still shines around the Moon's
edges.
A Hybrid Solar Eclipse is an eclipse that
starts as an annular solar eclipse, then
becomes a total solar eclipse and at the end
returns to an annular solar eclipse. The
total eclipse phase of a hybrid eclipse
tends to be short in duration.
Meteor Shower Events: When the Earth’s
orbit crosses the path of debris left behind
by a comet, there is a meteor shower as the
dust particles burn up in Earth’s
atmosphere. You can select to display all
meteor showers or only the major meteor
shower that average more than 10 meteors
per hour.
