So
What Exactly
is Astronomy? |
|
|
|
Study
of the Cosmos
|
|
Astronomy
is the scientific study of universe and the objects
in it. Moons, stars,
planets, nebulas, galaxies, comets and everything
you can see on a dark night are all part of the astronomical
realm.

How
Does Astronomy differ from Astrology? |
|
|
|
Comparison
|
|
There
is a big difference between astronomy and astrology.
Astronomers explore the science of the Universe. Astrologers
monitor how the moon, sun, planets and stars are related
to life and events on Earth. Astrology is based on
the belief that the heavenly bodies form patterns
and shapes that can reveal a person's character or
future.

How
do I know Which Telescope is Right For Me? |
|
|
|
Choosing
Your Scope
|
|
Figure
out what your observing priorities will be before
you buy. Some telescopes are better for planetary
viewing (reflectors, refractors), while others offer
improved light gathering capabilities and are perfect
for observing stars, galaxies and nebulas (dobsonians,
schmidt-cassegrains).

What
is a Halo? |
|
|
|
Refracted
Light
|
|
Halos appear when ice crystals in the
atmosphere refract incoming sunlight and moonlight.
On especially cold days and nights, sharp and colourful
peaks of light can appear on either side of a halo.
These are commonly known as sundogs or moondogs.

What
Can I See Without A Telescope? |
|
|
|
Observation
|
|
There
are countless astronomical objects you can discover
with a pair of binoculars or even your naked eye.
Watch the aurora borealis, track the phases of the
moon, record the rise and set times of constellations,
count the number of shooting stars during a meteor
shower or follow the position of the planets along
the ecliptic all fun astronomical exercises
that don't require a telescope.

What's
So Cool About Our Sun? |

|
About
Our Star
|
|
The
Sun isn't just a daily visitor to our skies, it's
an integral part of our existence. The
Sun is one of over 100 million stars in the Milky
Way galaxy. The Sun is about 25,000 light years from
the centre of the the Milky Way galaxy and 150 million
kilometres from Earth. We observe solar activity to
help us predict auroras and prevent damage to satellites
caused by the solar wind. The Sun was born 4.6 billion
years ago and will remain in its current state for
another 5 billion years. Powered by nuclear fusion,
it is made up mostly of hydrogen and helium atoms.

Why
do I see light and dark surface
features on the moon? |
|
|
|
Lunar
Landscape
|
|
The
moon has dark and light areas easily visible from
Earth. The dark areas are ancient lava flows, the
result of a violent period in the moon's history 3.5
billion years ago. The light areas are rugged highlands,
remnants of the moon's outer crust.

What
is the Ecliptic? |
|
|
|
Path
of the planets
|
|
An
easy way to find planets in the sky is to first find
the ecliptic. The ecliptic is the apparent path of
the sun across the sky. The moon and planets follow
roughly the same path. The band of constellations
located near this path is called the zodiac.
