Course Overview

For thousands of years, the star-filled sky has been a source of wonder, discovery, entertainment, and instruction. Ancient people from nearly every continent and culture wove exciting stories about the mythological figures they saw in the heavens. People also used the sun, moon, and stars for time-keeping and navigation. And careful observers throughout Europe, the Middle East, Asia, and elsewhere kept precise astronomical records, eventually paving the way for the Scientific Revolution and its remarkable discoveries about the nature of the universe.

Even today, watching the sky has not lost its fascination. Equipped only with a pair of eyes or, at most, binoculars and a small telescope, you can behold marvels such as these:

  • The jewel-like star cluster called the Pleiades in the constellation Taurus, easily visible with the naked eye and even more magnificent through a pair of binoculars
  • The broad band of the Milky Way arching across the summer sky; the band is the plane of our galaxy seen edge-on from the inside
  • The Perseid meteor shower, a celestial display that peaks in mid-August of every year when Earth passes through debris from Comet Swift-Tuttle
  • The cratered face of the moon, stark evidence of the violent era after the birth of the solar system—a record almost completely erased from Earth due to weathering
  • The four Galilean moons of Jupiter, named after Galileo, whose discovery of them in 1610 helped overthrow the geocentric model of the universe
  • A total solar eclipse, an awe-inspiring spectacle that occurs somewhere on Earth roughly every 18 months and is well worth traveling thousands of miles to see

Best of all, the endlessly interesting sky is just overhead wherever you are. All you need to feel at home in its limitless expanse is Our Night Sky, a richly illustrated 12-lecture course that gives you an unrivaled tour around the sky while teaching you about the science, culture, technology, and pure pleasure of stargazing. Our Night Sky focuses on the view from the Northern Hemisphere, reflecting the origins of the most familiar constellations in this region. However, the final lecture completes your tour by covering the most notable sights in the Southern Hemisphere.

View the Riches of the Universe from Your Own Backyard

From asteroids to the zodiac, from the Big Dipper to variable stars, Our Night Sky is designed to provide a comprehensive overview of what there is to see and the best way to see it, whether you live in the city or the country, whether you are a novice observer or an old hand at astronomy who needs a refresher on constellation and star names, locations, lore, and what to expect from season to season as the heavens present a gloriously changing panorama.

Under the guidance of award-winning astronomer and Professor Edward M. Murphy of the University of Virginia, you will learn

  • how to use a planisphere (star finder) or other star map to quickly orient yourself to the sky for any given date and time, and how to use these aids to find your way among the constellations;
  • how to read celestial coordinates to locate objects precisely, and how to find the north or south celestial poles, the celestial equator, the ecliptic (the sun's apparent path during a year), the vernal equinox, and other important landmarks;
  • how to appreciate the deep cultural roots of astronomy, which lie in humankind's universal quest to understand the heavens through vivid stories that have never lost their power and charm;
  • how to enhance your observing experience by selecting the right equipment from a bewildering array of choices in binoculars, telescopes, eyepieces, mounts, and other hardware; and
  • how to decipher the science behind planets, stars, and galaxies by learning the fundamentals of solar system structure, star types, stellar life cycles, galaxy classification, and other information that will enrich your observing.

Above all, you will better appreciate how our view from Earth reflects a hidden order—a structure that was discovered by sky observers long ago, who drew on centuries of observations to put together the picture we now learn from textbooks. As you watch the sky appear to rotate around the celestial pole over the course of a night, you will almost feel Earth turning beneath you, as it in fact does. As you look at a phase of the moon, you will automatically envision the relative positions of the sun, moon, and Earth that produce this view. As you observe the constellations slowly shift as you go out at the same time every night, you will know that you are seeing the effect of Earth's revolution around the sun.

In short, you will gain a truly cosmic perspective on our world. Equipped with this outlook, and with the extensive science, history, mythology, observing tips, and other background provided by Professor Murphy, you will be ready to step outside, look up, and become a space traveler from your own backyard.

The Night Sky Planisphere is Included with This Course! Along with this course you will receive the same Night Sky Planisphere Star Chart used by Professor Murphy throughout his lectures. This sturdy, easy-to-use star finder is an invaluable aid for locating major constellations and stars visible in the Northern Hemisphere. The Planisphere is included with DVD purchases only.

Our Night Sky is rated 4.5 out of 5 by 196.
Rated 5 out of 5 by from Very Informative Instructor very well spoken and knowledgeable. Starting using info as soon as it got to the point where planets are identifiable.
Date published: 2020-08-15
Rated 5 out of 5 by from Great course even for a seasoned observer. I've been observing the sky for many decades with a variety of telescopes. I wholeheartedly enjoyed this course and I even learned a good bit of history from it. Practical, expertly presented and geared toward amateur observers. The instructor speaks quickly and covers a lot of material so I did have to stop and rewind quite a bit to get the most from the course; that criticism is trivial. The material is lasting and should never be "out of date". A hands on practical treatment of the subject that compliments the theoretical courses offered here. A true 5 star treatment of the subject.

Rated 4 out of 5 by from Lot of good information Too much information, too fast. Speed 0.5 is too slow, doesn't sound good and 1.0 is too fast. Consider 0.75

Rated 5 out of 5 by from Outstanding Introduction to the Night Sky I thoroughly enjoyed this course. I thought the presentation was excellent. Each 30+ minute lecture is filled with interesting information and gradually makes you feel more at home looking up into the night sky. It's a lot to take in, but it is really worthwhile as he explains the night sky with an impressive depth of knowledge and passion for his subject. I would highly recommend this course.

Rated 4 out of 5 by from Good astronomy course, but a little heavy on the myths.
Date published: 2020-05-29
Rated 5 out of 5 by from Stargazing for Beginners and Everybody Else Too Double stars. Star clusters. Nebulae. Variable stars. Blue stars. Red stars. Giant stars. Dwarf stars. Rocky planets. Gas giants. Moon craters and moon mountains. This course helps you find all these and more. Professor Murphy starts with the Moon, then the solar system, and works outward to the constellations, deep-sky objects, and galaxies outside our own. Once the basics are covered, he takes the seasons and hemispheres in turn. What can you see in the summer sky? The winter sky? And so on. The course is well-structured from start to finish. Contrary to some negative reviews, I cannot agree that he speaks too fast or is disorganized. On the contrary, I find his presentations very well ordered and the entire course scrupulously structured. For me, the strength of this course is that Murphy pitches it to anyone who is interested in the night sky. He makes it equally accessible to people with telescopes, people with binoculars, and people who are stargazing with just the naked eye. He does not talk down, and does not assume the viewer has a background in astronomy. Etymologies, tales of discovery and mythologies of various peoples associated with different constellations add interest along the way. If you are fortunate enough to see the night sky where you live, or can get somewhere you can, and if you have any interest in astronomy at all, this course is an excellent place to start. Murphy provides not only
