Most of the time, astronomers derive information from an analysis of the light or the motions of celestial bodies, a process that, to the uninitiated, may seem more like sorcery than science.
In fact, astronomy is a challenging science, but not because the universe is inaccessible in the conventional sense..
It is concerned with the evolution, physics, chemistry, meteorology, and motion of celestial objects, as well as the formation and development of the universe.” One of the most important aspects of astronomy is its ability to help us understand our place in the universe..
Astronomy is the study of everything in the universe beyond Earth's atmosphere.
That includes objects we can see with our naked eyes, like the Sun , the Moon , the planets, and the stars .
It also includes objects we can only see with telescopes or other instruments, like faraway galaxies and tiny particles..
Astronomy is a science that seeks to explain everything that we observe in the Universe, from the comets and planets in our own solar system to distant galaxies to the echoes of the Big Bang..

Aristarchus of Samos (310-230 BC) Aristarchus of Samos was an ancient Greek mathematician and astronomer that is credited with having created the first-known map of our solar system, which placed the Sun at the center and Earth as a planet revolving the Sun..
Astronomy has and continues to revolutionize our thinking on a worldwide scale.
In the past, astronomy has been used to measure time, mark the seasons, and navigate the vast oceans.
As one of the oldest sciences astronomy is part of every culture's history and roots..
Isaac Newton (1642–1727)
Isaac Newton, one of the greatest scientists of all time, is mainly remembered for his work on gravity.
He also made major contributions to astronomy through his work on optics, experimenting with the surfaces of lenses to see if he could eliminate chromatic aberration..
Throughout History humans have looked to the sky to navigate the vast oceans, to decide when to plant their crops and to answer questions of where we came from and how we got here.
It is a discipline that opens our eyes, gives context to our place in the Universe and that can reshape how we see the world..
