What you'll learn
- The most beautiful objects in the universe are nebulae. They come in all shapes and sizes and colors, but what are they really? Learn to differentiate between different kinds of nebulae and find out how they get their names. Why is the galaxy littered with them and do the pictures we see really represent what they would look like if we went there?
- What are nebulae and their charactersitics
- How to observe nebulae with your naked eye, binoculars or telescope
- How images are captured and colored: Case study using the Hubble Space Telescope
- How nebulae get their names
- The Orion Nebula
- Naming and categorizing nebulae using the Messier catalog system
- Naming and categorizing nebulae using the New General Catalog system
- Five Types of Nebulae and their characteristics
- Emission nebulae
- Dark Nebulae
- Reflection Nebulae
- Planetary nebulae
- Light, images and the coloring of space photos
- Types of Light:
- Visible and invisible light

Description
The most beautiful objects in the universe are nebulae. They come in all shapes and sizes and colors, but what are they really? Learn to differentiate between different kinds of nebulae and find out how they get their names. Why is the galaxy littered with them and do the pictures we see really represent what they would look like if we went there?

My name is Tony Ceraso and I will be your instructor. I sometimes run the planetarium and have written curriculum for the National Air and Space Museum in Washington, DC. I have also written curriculum for NASA’s school visitation program and teach on the college level in NJ.
My goal is for you to thoroughly enjoy this lesson. I love astronomy and I want nothing more out of our time together than for you to have a greater appreciation for the universe through the understanding of this material. Besides the lesson I’m going to preview for you now, the course includes warm up activities, test questions, and cross-curricular activities for you to download as a supplement.
Who this course is for:
- Anyone who want to know more about Astronomy
