"This title shows how a group of European scientists, in the span of roughly one hundred and fifty years (early 1500s to the mid-1600s) and working through direct observation, overturned the centuries' old accepted view of a geocentric universe. Through their research and writings, they proposed and described a new order of things in which the Earth orbits the Sun. In so doing, these scientists--Nicolaus Copernicus, Johannes Kepler, Tycho Brahe, Galileo...

How do we know that the Sun is at the center of our solar system? This scientific theory is know as heliocentrism. This fascinating book looks at the historical controversies that surround the theory of heliocentrism and tells the stories of the scientists who worked on the theory. It also examines how the theory of heliocentrism was arrived at, how it was tested, and what impact the theory has had on our understanding of science today.

"Explore the fascinating history of earth and space science! What are Earth's systems, cycles, and resources? What are the solar system, lunar phases, and gravity? Who first studied these concepts? And who later used those early theories to develop these ideas further?"--

Within galaxies, stars grow from clouds of gas and dust, shine brilliantly, and die stunning deaths.
