Ch 11: Space Science

About This Chapter

Use the following video lessons and quizzes to help you understand space exploration and components of the solar system. Learn about inner and outer planets, main sequence stars and reflector telescopes.

Space Science - Chapter Summary

If you need to refresh your memory about how the earth moves or how space exploration has impacted technological advancements, check out the lessons included in this chapter. You can begin by studying Earth's orientation in the universe. Introductory lessons also outline classes of stars and show you how their colors can be used to gauge their surface temperatures. Watch as instructors discuss the stages of a star's life cycle, from its development into a protostar to its dissolution into a white dwarf, black hole or neutron star. You can even discover the types of radio, gamma ray, X-ray, reflecting and refracting telescopes used to detect visible light of varying wavelengths.

Characteristics of the solar system's inner, outer and dwarf planets are also covered, and you can round out your study of space science by exploring additional components of the solar system, like the Kuiper Belt and the Oort Cloud. Topics covered by this chapter include the following:

  • Star types and life cycles
  • Types of telescopes
  • Impacts of space exploration
  • Inner, outer and dwarf planets

This space science chapter, which is taught by professional educators, features short entertaining video lessons and self-assessment quizzes. You can take the quizzes before viewing the video lessons to gauge your knowledge of space science and then again after watching to see if you've fully absorbed the material. There are also transcripts you can use to review key vocabulary terms and concepts.

Types of Stars by Size, Color and Life Cycle

1. 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.

Star Formation: Main Sequence, Dwarf & Giant Stars

2. 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 Telescopes: Radio, Reflecting & Refracting Telescopes

3. Types of Telescopes: Radio, Reflecting & Refracting Telescopes

Learn about the different types of telescopes that astronomers use: X-ray, radio, gamma ray, reflecting and refracting. Learn what the differences are between them and what different things they show us about the universe.

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

4. 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

5. 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

6. 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.
