Chart the galaxies: types, evolution, and beyond

Are you fascinated by the night sky and the myriad mysteries it holds?

If so, dive into an exhilarating journey through the cosmos with this online course from the experts at the University of Lincoln.

From the spiraling arms of a barred-spiral to the peculiar structure of jellyfish galaxies, your understanding will stretch across the universe and beyond.

Explore the variety of galaxy types, from spiral to irregular

This course offers a comprehensive look at the breathtaking variety of galaxies, from the well-structured spirals and barred spirals to the intriguing irregular and jellyfish galaxies.

Starting with the basics, you’ll learn about different galaxy classifications and their unique characteristics. Whether you’re a seasoned astronomer or a curious novice, this course is designed to build your understanding from the ground up.

Reflect on the cosmic significance of galaxies in our universe

Beyond their stunning beauty and complex structures, galaxies hold deeper cosmic significance. This course invites you to explore not only what galaxies are–a bound collection of stars, gas, and dust–but also why they matter.

Delve into the origin stories of galaxies through the top-down and bottom-up formation theories and discover the role galaxies play in the broader context of the universe.

Connect theoretical knowledge with real astronomical observations

Join us on this cosmic voyage to decode the mysteries of the universe. Through engaging content, expert teaching, and interactive learning, this course will expand your horizons and equip you with the knowledge and skills to explore the galaxy.

With access to leading astronomers from the University of Lincoln, prepare to unlock the secrets of galaxy formation and classification.

Skip to 0 minutes and 1 second Within our solar system lies the planet Earth, where we live. But where is the solar system? Well, it’s a small part of the Milky Way Galaxy, a vast collection of gas, dust, stars and their solar systems bound together by gravity. I’m Doctor Phil Sutton, a senior lecturer in astrophysics and the programme leader for the Physics with Astrophysics programme at the University of Lincoln. I have extensive expertise in teaching all aspects of astronomy, from the solar system and planets to galaxies and cosmology. This online course will introduce you to the vast variety of galaxies in our universe, where you’ll investigate the underlying processes that have created them.

Skip to 0 minutes and 39 seconds You will learn to analyse galaxies and determine their type on the Hubble Classification System. The course will explore different types of galaxies like spiral, barred spiral galaxies, irregular, lenticular, elliptical and even jellyfish galaxies, along with how they form and how we calculate distances to them. This will be assessed with a weekly quiz to test the learner’s knowledge. No previous experience is necessary to enrol in the course. All you need is a passion for astronomy and an interest in exploring the wonders of galaxies. This course will be particularly valuable for university applicants who are still undecided on the areas of interest to study.

Skip to 1 minute and 18 seconds Explore the breathtaking expanse of galaxies, from majestic spiral arms to mysterious black holes in our online course dedicated to galaxies, where you’ll begin to uncover the universe’s secrets step by step.
