Use
this
graph
to
map
the
distribution
of
globular
clusters
in
the
galaxy.
It
is
important
to
note
that
the
Sun
is
at
the
center
of
the
graph.
Note
on
the
scale
of
thi
the
same
point
in
the
center
of
the
graph.
Question
1:
Place
an
“X”
on
the
graph
at
the
center
of
the
distribution
of
globular
clusters
you
plotted.
You
might
do
this
in
pencil
so
you
can
examine
your
result
and
make
adjustments.
Question
2:
|
Now
using
the
graph
and
the
position
that
you
marked
for
“X”,
then
determine
the
right
ascension
(h
:
min)
and
distance
in
kilo-light-years
and
put
your
answers
in'the
boxes
below.
Remember
again
that
there
is
60
minutes
in
an
hour,
not
100!

Question
3:
Now
that
you
have
a
graph
of
the
distribution
of
globular
clusters,
use
Harlow
Shapley’s
assumption
that
the
center
of
the
Milky
Way
galaxy
is
located
at
the
center
of
the
distribution
of
globular
clusters.
Do
you
think
that
the
Sun
is
in
the
center
of
the
Milky
Way
galaxy?
Explain
how
you
know
using
a
complete
sentence.

Question
4:
On
the
faded
image
version
of
Figure
2
below,
place
an
X
at
the
location
of
the
center
of
the
Milky
Way
galaxy
and
place
dots
showing
the
likely
positions
for
six
or
seven
globular
clusters.

Question
5:
Write
the
word
“BULGE”
on
the
faded
picture
above
to
indicate
the
location
of
the
galactic
bulge.
Question
6:
In
addition
to
the
Milky
Way,
do
you
see
any
other
galaxies
in
the
image
shown
in
Figure
27
If
so,
place
a
“G”
on
a
couple
of
them
in
the
faded
picture.
Question
7:
If
the
super-massive
black
hole
that
is
located
in
the
center
of
the
Milky
Way
galaxy
(you
marked
it
with
an
X
above)
swallowed
a
large
amount
of
gas,
and
consequently
emitted
a
burst
of
light,
how
long
would
it
take
us to
observe
it
from
Earth?
(Consider
the
definition
of
kilo-light-years
and
use
the
numerical
result
from
this
lab.)
