“Perfect” Thermal/Planck/Blackbody Radiation  Temperature “Perfect” Spectral Line Radiation  Material Composition Q: How can we use Light to detect Motion…?

“Doppler Shifts”…for Sound

“Doppler Shifts”…for Light

Stellar Companions… “Binary / (Multiple) Stars” “Visual Binaries” (not mere “Optical Double Stars”) are very convenient… but what if you can’t separate them?

A “Spectroscopic Binary” Star System

Detecting Planets in Other Solar Systems… “Direct Imaging”…? (Possible but Very Difficult!)

Q: How to detect dim “Extrasolar Planets” (“Exoplanets”)? A: Use Newton’s Third Law! (“Action-Reaction”… i.e., “Force-Counterforce”)

Other Exoplanet Detection Methods (e.g., the Transit Method)
