The night sky that we see is the best example of Nature’s recurring marvel.
It is an open Observatory in which we can make a note of all the observations. Astronomy,
the “science of the stars,” is concerned with the ‘physical universe.’
This science deals with Planets and their Satellites, including the Earth and Moon,
with Comets and Meteors, with the Sun, the stars and clusters of stars, with the
interstellar gas and dust, with the system of the Milky Way and the other galaxies
that lie beyond the Milky Way.
The most comprehensive of the sciences, astronomy is also regarded as the oldest
of all. People of ancient times were attentive watchers of the skies. They were
attracted by the splendour of the heavens, as we are today, and by its mystery that
entered into their religions and mythologies. Astrology, the pseudo-science, which
held that, the destinies of nations and individuals were revealed by the stars,
provided at times another incentive for attention to the heavens. An additional
incentive to the early cultivation of astronomy was its usefulness in relation to
ordinary pursuits. The daily rotation of the heavens furnished means of telling
time. The study of heavenly bodies has led to the evolution of time keeping. The
cycle of the moon's phases and the westward march of the constellations through
the year were convenient for calendar purposes. The pole star in the north served
as a faithful guide td the traveller on land and sea. These are some of the ways
in which the heavens have been useful to man from the earliest civilizations to
the present.
The value of this science, however, is not measured mainly in terms of economic
applications. Astronomy is concerned primarily with an aspiration of mankind, which
is fully as impelling as the quest for survival and material welfare, namely, the
desire to know about the universe around us and our relation to it. The importance
of this service is demonstrated by the widespread public interest in astronomy and
by the generous financial support that has promoted the construction and operation
of large telescopes in increasing numbers. Nowhere in the college curricula can
the value of learning for its own sake be more convincingly presented than in the
introductory courses in astronomy. It is the purpose of astronomy to furnish a description
of the physical universe, in which the features and relationships of its various
parts are clearly shown. At present the picture is incomplete. Doubtless it will
always remain incomplete, subject to improvements in the light of new explorations
and viewpoints. The advancing years will bring added grandeur and significance to
the view of the universe, as they have in the past. With a Scientist President,
we are just about going in the correct direction. Astronomy is a vast subject &
this excerpt will provide just a peek at the subject. It is just the beginning &
remember, universe is endless…
