Exploring the Universe: Detecting Motion, Planets, and Life Beyond

Learn about using light to detect motion, composition of materials through spectral line radiation, and methods for finding exoplanets and molecules of life in other solar systems. Explore the Doppler shifts for sound and light, spectroscopic binary star systems, direct imaging challenges, and newton's third law in exoplanet detection. Discover the convenience of visual binaries and techniques like the transit method to identify exoplanets. Visit the provided link for a catalog of habitable exoplanets and delve into the fascinating world of stellar companions and binary stars.

Presentation Transcript

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

  2. “Doppler Shifts”…for Sound

  3. “Doppler Shifts”…for Light

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

  5. A “Spectroscopic Binary” Star System

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

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

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

  9. (http://phl.upr.edu/projects/habitable-exoplanets-catalog)

  10. Detecting the “Molecules of Life” in Exoplanet Atmospheres…!
