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 4.4 out of 5 by 157.
Rated 4 out of 5 by from Good summary of stargazing techniques The professor does a good, comprehensive job of discussing the aspects of viewing the night sky. Reflects both hemispheres although concentrates on the Northern Hemisphere where most participants are likely located. Include good discussion and recommendations on use of various pieces of equipment used in the process, including the recommended solution. Explains the Sky Planisphere included with the course. While helpful, could have been expanded.

Rated 5 out of 5 by from Perfect Introduction to Astronomy This course is especially good for people just starting to learn the science of Astronomy. It clearly explains the Sky and the equipment the amateur Astronomer might use to observe it in a way that a layman can understand. I am going on my third time through the course!!
Date published: 2018-10-06
Rated 5 out of 5 by from Very informational and professional This course was very well presented and professional. The professor was very knowledgeable in the night sky and I found the course to be very exciting, educational, well paced and covered a variety of astronomical topics!

Rated 5 out of 5 by from Fabulous Northern Night Sky Toolkit This course operates well on multiple levels for sky observation. L1 includes clear instructions for use of the included planisphere for those of us impatient to start. Pay close attention to L2-3 if you are thinking of buying a telescope. Take notes, because Murphy’s explanations of the differences between eyepieces, 2X Barlow lenses, focal length vs magnification/field of view, magnification based on aperture size & eyepiece, chromatic aberration, "aperture fever", refractor vs reflecting vs catadioptric telescopes WILL ALL BE VERY IMPORTANT FOR YOU to grasp. The great part of L2-3 is that his explanations are extraordinarily clear. The difficult part is that he does talk rapidly AND the guidebook doesn't annotate a lot of this. Take marginal notes, they will serve you well. L4-6 provide wonderful hints on moon observation as well as a valuable tract on why you need to understand planet opposition. At the end of the guidebook is an extremely valuable table to alert you to the best opportunities. Other astronomic topics include ecliptic, blood moon, meteors, etc. L7-11 start with a general view of the Northern Sky and then Murphy discusses each season in a separate chapter. Here the guidebook (plus some handwritten notes) is useful as the written material strains out the much of the folklore. Folklore is useful to help one remember things but distracting if repeated by replay of the course. L12 was really enjoyable as I now have a much better idea of what my friends “Down Under” see. Finally, Dr. Murphy has kindly done an amazing job with his appendices. His discussion and tables include: “The 88 Constellations with Selected Bright Stars”, “The 30 Brightest Stars”, “Planetary Data", and "The Best Annual Meteor Showers". These are extremely useful in marking anticipated important events on your calendar. Since they help you plan so far ahead, his tables are easier to use than most apps, which concentrate on events of the day. CONCLUSION: Take notes, replay the season chapter for the quarter you are in, join a local astronomy club, and enjoy a captivating show every generation has enjoyed prior to the industrial revolution.

Rated 5 out of 5 by from Well done. Excellent well thought out presentations. Good mix of mythological tradition, science, and application for the amateur observer. An introduction for . more learning
Date published: 2018-07-21
Rated 4 out of 5 by from Good The professor's delivery is good but too fast. Also he needs to have better illustrative materials of larger areas of the sky and then zoom in on the specific topics discussed. Enjoyed the use of historical tales and myths for the presentation of the constellations to make them easier to find. Would like information on the course outline of where city folk can see the night sky free of light pollution and other atmospheric issues.
