Using this system for the sky, plot the location of the Sun at Noon on Feb 14th.  Altitude = 30^o , Azimuth = 170^o (SSE)

Plot the movement of the Moon in the sky.  Start: Altitude = 33^o , Azimuth = 144^o (SE).  End: Altidue = 45^o, Azimuth = 200^o (SW)

Using this system, plot the locaiton of the brigthest star in the sky (Sirius).  Right Ascension = 6hr 45min, Declination = -16^o

If the coordinates of Pollux are the following: Right Ascension = 7hr 45min, Declination = 28^o at 6pm on Feb 14.  What are its RA and Dec coordinates at 11pm on this date?

Which system RA/Dec or Alt/Azi is better for RIGHT NOW sky watching?  Explain

The pulling of one galaxy on another can cause the shape of galaxies to evolve and change over time by this event?

In approximately 3 billion years our Milky Way galaxy will collide with what?

Astronomers use the process of _______________ and _______________ to explain how galaxies evolve and change shape

In this theory of galaxy evolution, younger galaxies are ____________ shaped and eventualy flatten into _______________ shapes.

In this theory of galaxy evolution, galaxy start off as _____________ shapes and become _____________ shaped when all the gas is used up to make new stars.

Identify the Central Buldge:

Identify the Disk of the galaxy: 

Identify the Arms of galaxy:

Identify the Halo:

Identify the Globular Clusters:

This region is where the sun in located

This region contains gas and younger stars.

This region contains a supermassive blackhole to hold the galaxy together.

This region contains millions of older stars (used in the Center of the Galaxy Lab).

This region is where you can find globular clusters:

When galaxies collide, this event almost never happens because of how large space is?
