RSI New Moon is intended for all teachers and students of basic Solar System phenomena at all grade levels.
It lets you demonstrate--and your students explore--the three-dimensional aspects of motion in the Solar System.
And even better, it's the easiest-to-use astronomy program you'll
- See--in 3D--the relationships between the Sun, Earth and
Moon as the Moon's phases change
- See how the shadows of the Moon and Earth cause eclipses,
and why we don't have eclipses every month
- See how the planets move, from Kepler's laws to retrograde
motion and more
- See how the night sky looks from anywhere on Earth, and
print out a chart of the sky that shows the constellations, the
locations of deep-sky objects, and even the locations of
Jupiter's Galilean moons
- Quickly show over twenty different
aspects of astronomy using New Moon's new Quick
- Plan viewing evenings by seeing what
deep-sky objects are up, whether you're using a telescope,
binoculars or just unassisted eyes
- The Teachers Guide describes a variety of concepts in
astronomy, and shows you how to use New Moon to help teach them.
Do all this and more without hours of manual reading or training. We've made
New Moon just like our
other programs: Easy to use. There are no menus and no "toolbars of confusion." Instead, there's
a simple interface and options that make sense rather than try to provide everything under the Sun (pun intended).
Don't waste an hour or more of classroom time having your students learn how to use a program when they could be
learning about the Moon and sky.

that the enlarged images are smaller than what you'll actually see
using the program, and that the image quality is consequently
reduced as well.
|The Phases screen gives you a 3D view of the Sun, Earth and Moon, illustrating the spatial relationships
for each phase. You can rotate and tilt the field of view while it's animating, show the ocean tides caused by
the Moon and Sun, and even look at phases of the Earth as seen from the Moon.
|The Eclipses screen illustrates why we have about two solar eclipses each year. You can follow the Moon's
motion around the Earth, and see the umbra and penumbra of each body. Close-up views show the Earth moving through
the Moon's shadow and vice-versa. You can set the program to show you the upcoming solar and lunar eclipses.
|The Planets screen shows you the Solar System in 3D motion. You can view the Sun and planets from a
fixed location in the Solar System, or lock on a particular planet and view it from another planet. This is great
for illustrating retrograde motion, Kepler's laws, and one of Galileo's critical observations: The phases of interior planets compared to those of exterior
|The Ecliptic screen shows how the Sun, Moon and planets travel along the ecliptic. Retrograde motion is
clearly seen when animating, particularly when the
"trail" feature is turned on. The Moon's phases are depicted,
and when planets pass behind the Sun or each other they're
drawn behind the obscuring body.
|The Sky screen provides a basic planetarium view that you can use to preview the night sky. You can also
easily change latitude and longitude to show what the sky looks like from anywhere on Earth.
Constellations can be turned on and off; right ascension and
declination grids are optional. The best and brightest
deep sky objects can be plotted, too--to help you make the
best use of your class viewing time.
|Saturn's rings open and close as our view
of it changes. Here are two screen captures from
August 2017 (left) when the rings are open and February 2025
when they're close to edge-on.

Note the umbra and penumbral shadows on the leftmost
diagram. The two smaller diagrams on the right show
the way the shadows fall on the body being eclipsed.
In this case, you can see the Moon's shadows passing across
||You can watch the motion of Jupiter's four Galilean moons--another demonstration of Kepler's laws. And you can also use the sky screen to print out the moon's configuration to help with an evening viewing session. These four big, bright moons can be seen using binoculars.

We've added features to make New Moon more useful--and we've kept
it easy to use, too. Here are some of the changes:
- You can choose from over twenty configurations that
illustrate specific concepts simply by making a few mouse
clicks. This "Q" feature makes it really easy to use New
Moon for demonstrations.
- The Phase, Eclipse and Planets
screens all show real stars and constellations in the
backgrounds so that your students can get a better idea of where
things are and how they move.
- The Eclipse screen now offers
four zoom levels. One shows the entirety of the Earths'
orbit so that you can better see the reasons eclipses are rare.
The Moon's orbit has be colored to show where it crosses the
- The Planets screen now has an additional way to
show retrograde motion by using a connecting line between
planets. Comets have been added, and you can see the
Earth's and Jupiter's moons. Right clicking on the planets
provides a wealth of information about them. You can also
show the planets' names on the main display, or choose to show
other characteristics such as speed and distance from the Sun.
The Ecliptic screen now allows you to show time trails of
- The Sky screen now provides the plotting
of deep sky objects by how they're best viewed--by eye,
binoculars, or a small telescope. You can choose to
display the best deep sky objects for urban viewers, too.
Right clicking on the objects provides basic information about
them and a brief description.
- Star charts printed from the
Sky screen now include the deep sky objects as specified, and
will provide a diagram of Jupiter's moons if the planet is
- New Moon is now a Windows- and Macintosh OS
X-friendly application. You can resize it, do screen grabs
(using other software), minimize it--just like any other
RSI New Moon has the following
- Windows 95/98/ME/2000/XP or Mac OS 10.3+ operating system.
Windows 95 must be Service Release 2 or later.
New Moon runs on both PowerPC and Intel Macs.
- Processor running at 500 MHz or faster. 1 GHz or faster is
- Screen display of at least 800x600 pixels
resolution and 16-bit color (SVGA mode). 1024x768 resolution
with 24- or 32-bit color (XGA mode) is preferred

This is standard on most computers
- Mouse or other compatible
Almost all PCs sold during the past several years meet these
requirements. We suggest that you download
the trial version if you would like to verify your system's
ability to run New Moon.
The Teacher's Guide for New
is a PDF file than can be read with
Adobe Acrobat. The version available here omits the
answers to the questions posed within it; the Teacher's Guide you
receive with the software will contain the answers.
