As the moon waxes (the amount of illuminated surface as seen from Earth is increasing), the lunar phases progress through new moon, crescent moon, first-quarter moon, gibbous moon, and full moon. The moon is then said to wane as it passes through the gibbous moon, third-quarter moon, crescent moon and back to new moon.
Astronomy is the oldest of the natural sciences, dating back to antiquity, with its origins in the religious, mythological, cosmological, calendrical, and astrological beliefs and practices of pre-history: vestiges of these are still found in astrology, a discipline long interwoven with public and governmental astronomy, and not completely disentangled from it until a few centuries ago in the Western World (see astrology and astronomy). In some cultures, astronomical data was used for astrological prognostication.
Ancient astronomers were able to differentiate between stars and planets, as stars remain relatively fixed over the centuries while planets will move an appreciable amount during a comparatively short time.

Astronomers are gravity experts. All of the heavenly motions described in the preceding chapters are dominated by gravitation. Isaac Newton gets the credit for discovering gravity, but even Newton couldn’t explain what gravity was. Einstein proposed that gravity is a curvature of space, but that only pushes the mystery further away. “What is curvature?” we might ask.
This chapter shows how scientists build theories to explain and unify observations. Theories can give us entirely new ways to understand nature, but no theory is an end in itself. Astronomers continue to study Einstein’s theory, and they wonder if there is an even better way to understand the motions of the heavens.
The principles we discuss in this chapter will be companions through the remaining chapters. Gravity is universal.

3. In the preceding chapter, we saw how the sun dominates
our sky and determines the seasons. The moon is not as
bright as the sun, but the moon passes through dramatic
phases and occasionally participates in eclipses. The sun
dominates the daytime sky, but the moon rules the night.
As we try to understand the appearance and motions of
the moon in the sky, we discover that what we see is a
product of light and shadow. To understand the
appearance of the universe, we must understand light.
Later chapters will show that much of astronomy hinges
on the behavior of light.
In the next chapter, we will see how Renaissance
astronomers found a new way to describe the
appearance of the sky and the motions of the sun, moon,
and planets.

days (~ 1 month).

8. The Phases of the Moon (3)

Moon’s surface

Excess gravity pulls

center of the Earth

Excess centrifugal
force pushes water
away from the moon
on the far side
12. Spring and Neap Tides
The Sun is also
producing tidal
effects, about
half as strong as
the Moon.
• Near Full and
New Moon,
those two effects
add up to cause
spring tides.
• Near first and
third quarter, the
two effects work
at a right angle,
causing neap
tides.
Spring tides
Neap tides
13. The Tidally-Locked Orbit of the Moon
The Earth also
exerts tidal forces
on the moon’s rocky
interior.
It is rotating with
the same period
around its axis as it
is orbiting Earth
(tidally locked).
We always see
the same side of the
moon facing Earth.
14. Acceleration of the Moon’s Orbital
Motion
Earth’s tidal bulges are
slightly tilted in the direction
of Earth’s rotation.
Gravitational force
pulls the moon slightly
forward along its orbit.
15. Lunar Eclipses
Earth’s
shadow
consists of a
zone of partial
shadow, the
Penumbra,
and a zone of
full shadow,
the Umbra.
If the moon passes through Earth’s full shadow
(Umbra), we see a lunar eclipse.
If the entire surface of the moon enters
the Umbra, the lunar eclipse is total.
17. A Total Lunar Eclipse (2)
A total lunar
eclipse can
last up to 1
hour and 40
min.
During a total
eclipse, the
moon has a
faint, red glow,
reflecting sun
light scattered
in Earth’s
atmosphere.
21. Solar Eclipses
The sun appears approx. as large in the sky (same angular
diameter ~ 0.50) as the moon.
When the moon passes in front of the sun, the moon can
cover the sun completely, causing a total solar eclipse.
26. Earth and Moon’s Orbits Are

Perihelion = position

27. Annular Solar Eclipses
The angular
sizes of the
moon and the
sun vary,
depending on
their distance
from Earth.
When Earth is near perihelion, and
the moon is near apogee, we see
an annular solar eclipse.
Perigee Apogee Perihelion Aphelion
29. Conditions for Eclipses (1)
A solar eclipse can only
occur if the moon passes a
node near new moon.
The moon’s orbit is inclined against the ecliptic by ~ 50.
A lunar eclipse can only
occur if the moon passes a
node near full moon.
