The search for life in other worlds begins with the search for a habitable planet. This book explores the (3z(BGoldilocks Zone,(3y (Ba defined area that is perfect for harboring life in our universe. Readers will find out how scientists are finding habitable planets by using terrestrial and orbiting telescopes to search these regions. Readers will also get to know how extreme zones on Earth are helping scientists redefine their concept of (3z(Bhabitable(3y (Band what kind of life we might find. Fascinating full-color photographs and artist renderings from NASA illustrate this fascinating hunt.

"The path to a broader mode of cosmic observation was blazed by a cadre of nineteenth-century amateur astronomers and inventors, galvanized by the advent of photography, spectral analysis, and innovative technology to create the entirely new field of astrophysics. From William Bond, who turned his home into a functional observatory, to John and Henry Draper, a father and son team who were trailblazers of astrophotography and spectroscopy, to geniuses of invention such as L?eon Foucault, and George Hale, who founded the Mount Wilson Observatory, Hirshfeld reveals the incredible stories--and the ambitious dreamers--behind the birth of modern astronomy."--.

Introduces readers to the different ways astronomers use science, technology, engineering, and math in their work every day. Also covers the steps a person can take to become an astronomer.

A biographical novel in verse of three different girls in three different time periods who grew up to become groundbreaking scientists.

Questioning established knowledge isn't usually a popular course of action. Galileo learned this throughout his life as he tested scientific theories using mathematical calculations. He challenged the Catholic Church and Aristotle, which got him into trouble, but also added him to the pantheon of great scientists. Readers learn all about Galileo's most important discoveries through the story of his life, complete with historical images. Sidebars add detail and understandable explanations to the main content, including concepts such as the scientific method and the planets orbiting the sun.

Chronicles the life of Galileo Galilei, focusing on his relationship with his eldest child Virginia, and explaining how she helped influence her father's work.

A biography of the German astronomer who discovered three laws of planetary motion.

The Milky Way, a galaxy about 100,000 light-years across, is our cosmic neighborhood. Scientists once thought the Milky Way was the only galaxy in the universe, but we now know it’s just one of billions. By studying galaxies and the stars and planets they contain, scientists have learned much about the universe and how it formed.
