Introduction

**Course Review: The Sun and the Total Eclipse of August 2017 on Coursera** If you've ever gazed up at the sky and marveled at the wonders of the cosmos, "The Sun and the Total Eclipse of August 2017" course on Coursera is a captivating gateway into understanding one of nature's most magnificent spectacles: a total solar eclipse. This course doesn't merely cater to those who enjoy astronomy for its visual splendor; it also delves into the scientific implications, making it an insightful experience for enthusiasts and learners alike. ### Course Overview The primary focus of this course is, of course, the total solar eclipse that occurred on August 21, 2017. It is perhaps one of the most awe-inspiring events that many will witness in their lifetime. The course begins with an introduction to the astonishing phenomena of the eclipse, describing how it feels to witness the sun being obscured by the moon, creating an eerie twilight and stirring reactions from both spectators and nature itself. The descriptions are evocative, painting a vivid picture of the event that can become a lifelong memory for those fortunate enough to observe it. ### Syllabus Breakdown The course is structured into five modules, each meticulously crafted to build understanding step by step. 1. **Introduction to the Sun and Eclipses**: This opening module sets the stage by explaining the mechanics behind eclipses, their rarity, and engaging participants to appreciate the difference between partial and total eclipses. It also introduces key concepts, such as the size of the sun and the existence of sunspots. 2. **Most of What We Know About the Sun is Learned From Light**: A pivotal segment that covers how we study the sun through visible and invisible light spectra, like ultraviolet and X-rays. It beautifully links atomic interactions to the light we perceive, encouraging an appreciation for the quantum properties of our universe. 3. **How Does the Sun Work? What Makes it Shine? What’s Inside?**: In this module, the course dives deeper into the inner workings of the sun. Participants will learn how we can infer what's happening at the core of the sun, revealing the immense energy production that sustains life on Earth. 4. **How Did the Sun Form?**: Here, learners explore the origins of the sun by examining stunning Hubble Space Telescope images of cosmic gas clouds that mirror the conditions of our solar system 4.5 billion years ago. This module beautifully connects the formation of our sun to broader cosmic phenomena. 5. **The Aug. 21, 2017 “Great American Total Solar Eclipse”**: This final module is particularly special and focuses on the eclipse itself. While this week can stand on its own for those in a rush, it is best appreciated after completing the previous four modules, which provide essential insights for understanding what to expect during the eclipse. ### Why You Should Take This Course This course stands out due to its engaging amalgamation of visual wonders and scientific exploration. The instructors utilize vivid, approachable language and stunning visual aids that not only captivate but also enhance comprehension of complex astrophysical concepts. By participating, you'll not only learn about the mechanics of eclipses but also develop a deeper appreciation of the sun’s role in our solar system and its various phenomena. In an era where online learning and remote education are becoming the norm, this Coursera course provides an excellent blend of knowledge and inspiration. It's perfect for anyone who has an interest in astronomy, whether you're a complete novice or someone with a basic understanding seeking to learn more. ### Conclusion "The Sun and the Total Eclipse of August 2017" course on Coursera is highly recommended for aspiring astronomers, educators, and anyone curious about the marvels of our universe. It’s an enlightening experience that combines scientific rigor with engaging storytelling. So if you're ready to embark on a cosmic journey that culminates in one of nature’s grand performances, enroll today and prepare to look at the skies with a newfound wonder!

Syllabus

Introduction to the Sun and Eclipses

In this module we describe what causes eclipses, how rare it is for any one place to experience a total eclipse, the dramatic difference between a total or a partial eclipse, and encourage you to see the total eclipse on Aug. 21, 2017. We also review the upcoming course topics, demonstrate how large the sun is, and introduce sunspots.

Most of what we know about the Sun is learned from Light

In this module we explain how astronomers use visible and invisible light (ultraviolet and X-rays) to study the sun. We learn that all light comes from atoms, and that the quantum world of atoms is like nothing you’ve ever seen! We see how the properties of light let us determine the sun’s temperature, its composition, and the important role of its magnetic fields.

How does the Sun work? What makes it shine? What’s inside?

We can’t see inside the sun with visible light, but there are ways to infer or even see down to the sun’s center, where vast amount of energy are generated, making possible life on earth.

How did the sun form?

When you look at Hubble Space Telescope images of beautiful clouds of gas in space you are seeing what happened in our own solar system 4 ½ billion years ago when the sun formed. This week we explain how that process works.

The Aug. 21, 2017 “Great American Total Solar Eclipse”

This Week 5 presentation concentrates on what will happen during the Great American Eclipse of Aug. 21, 2017. It may be viewed alone, or after Weeks 1-4. Weeks 1-4 give a lot of explanation of what you will see, so I hope you take the full course, but if you are in a hurry, this week alone will prepare you.

Overview

A total eclipse is one of the most spectacular sights you can ever see! It looks like the end of the world may be at hand. There is a black hole in the sky where the sun should be. Pink flames of solar prominences and long silver streamers of the sun's corona stretch across the sky. It gets cold, and animals do strange things. People scream and shout and cheer, and remember the experience their whole life. But total eclipses are important scientifically as well. They let us see parts of the su

Reviews

The peer review process was confusing when there were no submissions to review. Would like to have more communication about what to do in this instance.

The Course was great, except for two things. one it was too short :-), and two, the peer graded projects were confusing.

I learned a lot and wished I'd known how interested I am in physics. Looking forward to August 21, 2017. Thanks Dr. Doug for your teaching!

Good Knowledgeable course for all the students. This course has increased my knowledge about the solar system and earth.

It was short, sweet, very timely matched with solar eclipse.
