Many people think interplanetary space is empty. It is, in
fact, filled with cosmic rays, dust, and solar wind. Cosmic
rays are high speed sub-atomic particles. Interplanetary dust
consists of debris scattered by comets, and powder from asteroid and
meteoroid collisions. In addition, there is the solar wind,
which is made up of charged sub-atomic particles, mostly protons and
electrons emitted by the sun.
The particles of the solar wind behave as if they were sliding
along the lines of the sun's magnetic field, like beads sliding
along a wire. As the solar wind blows by each planet, it
distorts its planetary magnetic field, just like water is disturbed
by the bow of a boat.
The solar wind increases during eruptive bursts of solar
flares. This is why scientists directing the space shuttle
program observe the sun carefully, in order to avoid potential
damage from excessive solar particles. The solar wind from
flares in the sun penetrates the Earth's atmosphere around the
magnetic poles, often reacting with oxygen and nitrogen atoms in our
atmosphere. This creates the colourful shimmering Aurora
Borealis or Northern Lights and the Aurora Australis or Southern
Lights at the corresponding pole.
So next time it's windy on Earth, remember there are also windy
days in space.
MOVING
BEYOND MATTER
by Debbie Hughes
Wind brings change. Recently, I was talking with a relative
who lives thousands of miles away from where I live. She
resides near the deserts of Arizona. We were discussing the
hot, sunny weather they routinely experience there. She
commented to me that since it is seldom windy there, they do not
experience changing weather patterns. They seldom see storm
clouds or encounter the turbulent conditions which often accompany
change.
Often we refer to the winds of change when referring to new
movements in society. There is an understanding that the
present conditions are on their way out and a new pattern and new
circumstances are sweeping in.
You know, change is seldom easy. But it does seem to be a
given in today's world.
In all this we are called upon to respond. Some folk resist
change and fight against it. Others will embrace it.
Still others will find ways to adapt to the change and regain some
sense of equilibrium in their life. Few of us really like
change. Some need change. Many will be affected by
change which is now as inevitable as death and taxes.
Changes often happen to us. Circumstances change.
Health changes. Other people's decisions have a direct impact
on our lives.
Yet sometimes we choose change. When this happens, we
anticipate that these choices will somehow improve our lot in
life. We do them to make things better. This may be
beneficial for those we love, it may be more rewarding in some
way. Perhaps a change comes down to simply choosing to do the
right thing.
Changes that occur on the level of our spiritual orientation have
a significant impact on us. They affect our beliefs and
values, our relationships and our vision. These things are
often the result of internal processes that cause conviction of
their truth to grow within us. While this process of getting
to spiritual change is usually uncomfortable, marked benefits are
associated with the experience. Spiritual change is an
important aspect of our growth as persons.
