Stellar Distance 4.0
There is no single technique to measure distance in the Universe. Astronomers use the term Cosmic Distance Ladder. We are going to climb that ladder.  
Magnitude & Distance 3.0 How distance to celestial objects can be obtained from the object's luminosity or magnitude. We discuss flux; magnitude scale; distance modulus; standard candles.
