Summary:
The stars have always been a fascinating subject. Perhaps that's one
reason why astronomy is so popular these days.

In essence, Astronomy isn't just about studying stars, as most people
think. It's actually a study of celestial objects, which includes not
only stars but also planets, comets and entire galaxies. In fact,
Astronomy also studies different phenomena that come from outside of the
earth's atmosphere, such as auroras and cosmic background radiation.

The stars have always been a fascinating subject. Perhaps that's one
reason why astronomy is so popular these days.

In essence, Astronomy isn't just about studying stars, as most people
think. It's actually a study of celestial objects, which includes not
only stars but also planets, comets and entire galaxies. In fact,
Astronomy also studies different phenomena that come from outside of the
earth's atmosphere, such as auroras and cosmic background radiation.

In addition, Astronomy, is concerned with a host of other sciences,
including physics, evolution, chemistry, how celestial objects move and
how the universe was formed and developed. Scientists routinely use
Astronomy to test some of the most fundamental theories in physics, such
as general relativity. In attempting to explain astronomical phenomena,
astronomy joins hands with astrophysics.

Overall, Astronomy is among the oldest sciences known to mankind. Records
show that there were astronomers dating back to the days of ancient
Greece and India. This is probably where advanced observation techniques
originated. In addition, the scientific history of man shows how many
amateur astronomers have contributed and played an active role in
observing and discovering what is referred to as transient phenomena.

With the dawn of the 20th century, Astronomy was divided into two
sciences. These are observational astronomy and theoretical astrophysics.
The first one is concerned with getting data and this involves building
and maintaining a host of different instruments as well as processing the
results of the data it acquires. There are some who refer to this branch
of science as "astrometry" or simply as "astronomy". On the other hand,
theoretical astrophysics has to do with ascertaining the implications
that can be observed through a computer or through analytical models.

There are those who confuse modern astronomy with astrology but they are
two very different things. Astrology revolves around a belief system that
presupposes that the different positions of celestial objects have a
direct bearing on human affairs. In a nutshell, it is fortune telling
with the aid of the stars. Astronomy and astrology obviously share the
same common origins but most scientists and other knowledgeable observers
know that both fields are clearly distinct.
