1) The diagram below represents a pole-on view of Earth from outside the Milky
Way Galaxy. Earth is at the center, the lines show the various directions
of right ascension, and each circle represents a distance of 1 kiloparsec
from the Earth. Plot the right ascensions versus the distance of each
globular cluster in the list. What is the approximate right ascension
of the Galactic Center?
3 hours
6 hours
9 hours
12 hours
15 hours
18 hours
21 hours
2) Below is another diagram which takes a view from above the equator.
Again, Earth is at the center, and each circle represents a distance of
1 kiloparsec, but this time, the directions are degrees of declination.
Plot the globular cluster declinations against their distance. What is the
declination of the Galactic center?
+90 degrees
+60 degrees
+30 degrees
0 degrees
-30 degrees
-60 degrees
-90 degrees
3) According to the data given above, what is the approximate distance to the
Galactic Center?
1 kpc
3 kpc
5 kpc
7 kpc
9 kpc
4) In the direction of what constellation does the Galactic center lie?
Pegasus
Cetus
Orion
Sagittarius
Cancer
Leo
Virgo
Libra
Capricorn
Hercules
Aquila
5) Is the Galactic Center best viewed from the Northern or Southern
hemisphere of the Earth?
Northern hemisphere
Southern hemisphere
Both hemispheres can see the Galactic center equally well.
