If we had a new moon last
week on Sept 15 then what
would be the moon phase
next week on September 27?
$600
False, it is about ½
true or false, when the moon
is in its first quarter phase it
appears about 25% lit?
$800
First Quarter Moon
What phase occurs about one
week after the New Moon?
$1000
The phase will be full because it is rising
opposite the sun. If the moon is directly
opposite of the sun in the sky it will be a
full moon
If the moon rises at sunset, what
phase will it be in? Why?
$200
full
When the moon is directly
opposite the sun what phase
is it in?
$400
6 pm
If the moon rises at 5 pm
tonight approximately what
time will it rise tomorrow?
$600
Noon
When does the first quarter
moon rise?

What phase is highest in the
sky at sunset?

Another name for Galilean
telescope is

Keplerian telescopes are also
called
$600
lenses
Refracting telescopes use a
series of

A ____________ lens is used
in a Galilean telescope and
the image is

Collect a lot of light and focus it
what is the main purpose of
telescopes?
$400
ecliptic
What celestial line is a
product of the Earth’s orbit
around the Sun?
$600
chromatic aberration
what problem does a refractor
telescope have that a reflector
does not?
$800
resolution
the ability to distinguish
between two objects in the
sky is called
$1000
they can get more light and they have better
resolution
What are two reasons that
larger telescopes are better?
$200
to get above our atmosphere
Why put telescopes in space?
$400
Hubble
What was NASA’s first space
telescope?
$600
Air turbulance
Why do stars twinkle?
$800
Can be used day or night, not effected by
weather and allow us to view the universe
from a different wavelength
What are the advantages of
radio telescopes?
$1000
they have long wave lengths and poor
resolution
what are the difficulties with
radio telescopes?
