Astronomy: Exploring the Universe

Course Overview

Units at a glance

Day turns into night, and Summer turns into Fall. Why do we experience these predictable changes on Earth? In this introductory unit of Astronomy I, we will explore the systems and interactions between the Sun, Earth, and Moon. You will learn how the Earth’s motion in space causes us to experience days, nights, and seasons in a cyclic pattern.

In this unit we will take a journey through space and time from the beginning to the end of the universe. Can you think of anything larger or more expansive than the universe? How was the universe created? How is the universe changing? What exactly is our universe made from? These are all questions that scientists have been trying to answer since the idea of a universe was formed in the minds of our earliest cosmologists.

What are stars? Where did they come from? Will stars evolve with time? In this unit you will discover the secrets behind the stars in our night sky. We will solve the mystery behind why and how stars shine. We will explore the characteristics and composition of stars. You will learn how astronomers classify types of stars using the H-R diagram and how stars are identified within the celestial sphere. Finally, we will examine the evolution, or life cycle, of a star from conception to death.

Galaxies are beautiful, majestic, and mysterious places within our universe. Our home in the Milky Way galaxy is a galactic suburb, far from other galaxies. Our Sun is just one of approximately 500 billion stars in our galaxy, meaning that there could possibly be up to 500 billion solar systems, maybe like our own, in the universe. In addition, the Milky Way galaxy is only one of the 50 billion to one trillion galaxies that are thought to exist in our observable universe. Compared with the whole universe, our home, Earth, is like a speck of sand in the largest desert imaginable.

In this unit, we will examine and describe the evolution, organization, distribution, and differences among types of galaxies. You will be able to characterize the movement of galaxies within the universe and describe the properties of our own galaxy, the Milky Way. Finally, we will discover the incredibly mysterious and dark forces that shift and shape galaxies.

The inner planets of our solar system are more closely related than the outer planets of the solar system. These planets are sometimes referred to as terrestrial planets and include Mercury, Venus, Earth, and Mars. Although all of these planets are notably rocky and dense, each one is unique.

In this unit, we will examine the formation of our solar system and describe the unique features of the four inner planets, Mercury, Venus, Earth, and Mars. We will compare and contrast the characteristics of the inner planets. Finally, you will discover the special attributes that make life on Earth possible.

In this unit, we will examine the outer planets, Jupiter, Saturn, Uranus, and Neptune. We’ll learn more about their structure, motion, atmosphere, and moons. We’ll examine what space expeditions, observations, and mathematical predictions are telling us about these distant planets and their roles in our Solar System. Finally, we will learn more about the dwarf planet Pluto and examine the controversy over Pluto’s reclassification as a dwarf planet from its former classification as our Solar System’s ninth planet.

The Sun plays one of the most important roles in our Solar System and certainly life on Earth. In this unit, we will learn more about this closest star to Earth. We’ll discuss the structure and composition of the Sun, including the different layers of the Sun’s atmosphere. We’ll also learn how the Sun creates energy through nuclear fusion and the process by which this takes place. Finally, we’ll learn more about solar weather and the events that take place in and around the Sun, including sunspots, solar flares, and coronal mass ejections.

In this unit, we will examine comets, asteroids and meteors. Although smaller than the Sun, Moon, and planets, these celestial bodies are an important part of our Solar System. They can also produce dramatic visions in the Earth’s skies and have the potential to collide with the Earth. We’ll consider their composition, structure, and function in our Solar System.
