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.

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

2. 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

3. 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

4. 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.

Galaxy Formation: Spiral, Elliptical & Irregular Galaxies

5. 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.

Life Cycle of Black Holes

6. Life Cycle of Black Holes

Learn about black holes, their myths and their reality. Learn how black holes form after stars undergo supernovae and create singularities. Discover how big black holes grow, how scientists find black holes and where black holes are located in the universe.

Structure of the Sun
