Looking Up Features. The seven Looking Up features—
all of them new full-page art pieces—are designed to show
students how some of the astronomical objects discussed in
the text connect with the real sky that they can see overhead
at night. In particular, they show where a variety of the frequently
mentioned and important astronomical objects can
be seen. Each box presents a photograph of one or more
constellations in which nebulas, star clusters, and so forth
are identified and illustrated. These latter illustrations include
scale factors to help students visualize how even immense
objects many light years across can appear as mere
dots in the sky. Along with the illustrated objects, most of
the Looking Up features include a small insert to show how
the constellation’s stars are arranged in space.
The following are the Looking Up features
• Looking Up at the Orion, Chapter 1, page 26:
• Looking Up at the Summer Triangle, Essay 1, page 65:
• Looking Up at Taurus, Chapter 4, page 136:
• Looking Up at the Northern Circumpolar Constellations,
Chapter 5, page 174:
• Looking Up at Ursa Major, Chapter 12, page 369:
• Looking Up at Sagittarius, Chapter 15, page 440:
• Looking Up at M31 & Perseus, Chapter 16, page 471:
In constructing the Looking Up boxes,we have had to draw
upon many different sources for the distances and sizes of
the featured objects. For all but the very nearest of these,
distances (and therefore sizes) are poorly known. Thus,
none of the numbers appearing in these boxes should be
assumed to be precise.
Interactives. A total of 23 Interactives are now available on the Digital Content
Manager CD-ROM and at the Explorations Online Learning Center. These include 17
new Interactives. All Interactives are now programmed in Flash for a stronger visual
appeal.
Starry Night Planetarium Software. This software, now available free with the
purchase of this textbook, allows users to manipulate and take control of an accurate
visual representation of the sky.Users become active observers and gain a far better understanding of how the sky works.
Planetarium Activities. New activities to be integrated with the Starry Night planetarium software are now available at the end of most chapters.
Foldout: Scale of theUniverse. This two-page foldout shows the Earth, Sun,Moon,
and their orbits to scale, aswell as a“model”of some of the galaxies in the LocalGroup to
illustrate their sizes and separations. The other side of the foldout depicts deep-space objects
to scale. This foldout is constructed so students can easily leave it open and refer to it
while reading the text to gain a better sense of scale.
“What Is This?” Photographs. At the beginning of each chapter,
students are presented with a photo of an astronomical object
and asked to guess what it is. After reading the chapter, they should
have some idea of what is shown in the photo. The Answer is provided
at the end of each chapter summary.
New and updated images
• Transit of Mercury
• Computer simulation of the birth of the Moon
• Solar flare
• Computer simulation of the growth of structure in the early Universe
• Mars as viewed by the Opportunity and Spirit landers
Classroom Performance System and Questions. The Classroom Performance
System (CPS) brings interactivity into the classroom. CPS is a student response system
using wireless connectivity. It gives instructors the ability to ask questions and receive
immediate feedback from the entire class. CPS allows instructors to create their own
questions or use the astronomy questions provided by McGraw-Hill.
