TO THE SOLAR SYSTEM
Astronomy is the study of everything we can observe and imagine
beyond Earth—the Moon, the Sun, the Solar System with
all the planets and lesser objects in it, the Milky Way, and
the vastness of the cosmos. Astronomers investigate the kinds
and numbers of objects in the cosmos, the composition of the
objects, and the motions and interactions of the objects with
one another. Because Earth is part of this large system, the
science of astronomy includes the study of our own planet.
|
Astronomers ask fundamental questions: When and where did
the universe start? What gave birth to it? What is the destiny
of the universe? Space—the seemingly boundless vessel
holding billions upon billions of swirling galaxies—is
today's final frontier. Astronomers continue to be the pioneers
who first ventured into this vast environment, creating the
charts that will guide those of us ready to join the adventure.
