Ch 14: Space Science Overview

About This Chapter

Go over the basics of space science by watching our helpful online video lessons. This chapter contains information about the formation of the earth, moon, stars, and planets, characteristics of asteroids, and many more specifics about space.

Space Science Overview - Chapter Summary

Space is so complex that there is a whole field of science dedicated to studying it. Some of the major topics relevant to the scientific study of space are the subjects of the video lessons you will find contained in this chapter.

The instructors of these lessons will break this subject into much simpler subtopics that you can learn about from the comfort of your own computer, with lessons dedicated to the characteristics and formation of many of the most significant types of bodies in our universe. You will learn about where the universe itself came from, the formation of some of the major celestial bodies, and how our own Earth formed. Included in this chapter are specific lessons on:

  • Astronomy as a scientific field
  • Origins of the universe
  • The formation of stars
  • Planets of our solar system
  • The laws of planetary motion

When watching these lessons, you will notice that each video has tags that allow you to return to the most crucial points for each topic. If you wish to have hard copies of the lessons, the chapter provides transcripts of them as well. Finally, see how well you remember some of the main points that you learned about by taking the chapter's practice quizzes.

The Scientific Field of Astronomy

1. The Scientific Field of Astronomy

Space is a large and exciting place, full of things we have yet to discover. Astronomy aims to uncover the mysteries of space, something people have been fascinated with as long as they have been on Earth.

Origins of the Universe: The Big Bang and Expanding & Contracting Universes

2. Origins of the Universe: The Big Bang and Expanding & Contracting Universes

Students will learn the origins of the universe, the Big Bang theory, the timeline of the universe, how the universe is still expanding to this day, and what astronomers expect the universe to look like in the future.

Galaxy Formation: Spiral, Elliptical & Irregular Galaxies

3. Galaxy Formation: Spiral, Elliptical & Irregular Galaxies

This lesson explains how galaxies form, starting with the Big Bang. You'll also learn about the solar nebula hypothesis and three galaxy types, including spiral, elliptical, and irregular galaxies.

Formation of the Earth: Theories

4. Formation of the Earth: Theories

In this lesson, the theory of how the planet Earth formed will be discussed. This includes looking at how it differentiated into three layers, how it formed its atmosphere, water, and land features, and how it continues to evolve today.

Formation of the Moon: Theories

5. Formation of the Moon: Theories

Explore the four major theories on the formation of the Moon. The theories include the fission theory, capture theory, condensation theory and giant impact theory. Also look at both information supporting and flaws found in these theories.

Star Formation: Main Sequence, Dwarf & Giant Stars

6. Star Formation: Main Sequence, Dwarf & Giant Stars

Learn how stars are born, beginning with a protostar. Then learn about stars in later stages of life, including main sequence stars, brown dwarfs, red giants, and black holes.

Types of Stars by Size, Color and Life Cycle

7. Types of Stars by Size, Color and Life Cycle

Learn to identify the different sizes and colors of stars and how they relate to the star life cycle. In this lesson, we'll talk about spectral classification, how many stars there are of each type and the approximate color of the different classes of stars.

Structure of the Sun

8. Structure of the Sun

Discover the layers of the sun, including the core, radiative zone, convective zone, photosphere, chromosphere, and corona. Find out which layers you can see from Earth. Investigate what sunspots and solar flares are.

Four Stages of Planetary Development

9. Four Stages of Planetary Development

This lesson will describe the four stage of planetary development. They are, from past to present, differentiation, cratering, flooding, and slow surface evolution.

Inner Planets of the Solar System: Mercury, Venus, Earth & Mars

10. Inner Planets of the Solar System: Mercury, Venus, Earth & Mars

Take a tour of the four inner planets: Mercury, Venus, Earth and Mars. Known as the terrestrial planets, find out what makes each of them unique and how they are different from the outer planets, the gas giants.

Outer Planets of the Solar System: Jupiter, Saturn, Uranus, Neptune

11. Outer Planets of the Solar System: Jupiter, Saturn, Uranus, Neptune

Take a tour of the outer planets of our solar system: Jupiter, Saturn, Uranus, and Neptune. Find out what makes each of these gas giants unique and learn about Pluto, a dwarf planet.

Dwarf Planets of the Solar System: Pluto, Eris, Haumea & Ceres

12. Dwarf Planets of the Solar System: Pluto, Eris, Haumea & Ceres

Discover why Pluto had to leave the league of planets and was downgraded to a dwarf planet. Learn the definitions for planet and dwarf planet. Find out about the currently classified dwarf planets in our solar system: Pluto, Eris, Ceres, Haumea and Makemake.

Solar Nebula Theory & Patterns of Planetary Motion

13. Solar Nebula Theory & Patterns of Planetary Motion

This lesson will tie together the solar nebula theory and the patterns of motions of the planets in our solar system and why Venus and Uranus are exceptions in the solar system.

Kepler's Three Laws of Planetary Motion

14. Kepler's Three Laws of Planetary Motion

Find out about the interesting life and major contributions of Johannes Kepler. This lesson will also teach you how to find out how long it takes a planet to revolve around the sun!

Asteroids, Meteorites & Comets: Definitions and Characteristics

15. Asteroids, Meteorites & Comets: Definitions and Characteristics

This lesson will cover the definitions and characteristics of asteroids, comets and meteorites. It will also explore what impact they have had on Earth and the impact they might have in the future.
