Explore the Milky Way’s place in the universe and the variety of galaxies, including collisions and central black holes, and learn what galaxies are, how they differ, and their phenomena.
Explore the Milky Way's place in the universe and compare spirals, ellipticals, and irregular galaxies, including black holes, nebulae, and nearby neighbors like Andromeda.
Engage with test and discussion questions by printing them or answering onscreen, download the questions and answers from the resource center, and pause to study or quiz yourself.
Explore cross-curricular extension activities that connect the lesson to earth sciences by cataloging natural objects that exhibit logarithmic spirals and explaining how hurricanes form logarithmic spirals.
Explore how state curriculum standards apply to space science, including dedications and proper credit for public domain NASA and Hubble images in this astronomy course.
Explore astronomy, the study of celestial objects beyond Earth's atmosphere, using light and tools to measure distance with astronomical units and light years, and to understand galaxies and the universe.
Describe how eclipses form, define umbra and penumbra, and compare partial, annular, and total solar eclipses, plus lunar eclipses.
Discover how meteor showers arise from Earth passing through comet debris, and learn practical tips for watching meteors as naked-eye events under dark, quiet skies.
Explore how solar particles interact with Earth's magnetic field to create the northern and southern auroras, and learn where to see and photograph them.
Learn how the Artemis project aims to establish a permanent human presence on the moon, leverage the SLS and Orion, and collaborate with international partners to prepare for Mars.
Our solar system is immense, but it gets lost in the vastness of our Milky Way Galaxy. Look at our place in the galaxy and our galaxy’s place in the universe. Examine the different kinds of galaxies including galaxy collisions and the black holes in the center.

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.
