  1. Can You See My Point?! Why Multi-Wavelength Imaging is Crucial to Modern Astronomy.

  2. The Universe Primarily Consists of Matter and Energy Forms of Matter Atoms Molecules Polymers Substances Materials Mixtures Forms of energy Kinetic Heat Friction Light Sound

  3. Matter • All matter has mass and gravity • Atoms have small parts called subatomic particles • Protons (positive) • Neutrons (neutral) • Electrons (negative) • Every Element (atom type) varies in particle count. • Atoms can interact and emit energy from their motion. • Even electrons love to interact in all sorts of ways! Spin-Flipping, Electron Transitioning, Braking, and Knock each other out!

  4. Some Energy Can be Classified on the Electro-Magnetic Spectrum

  5. We can’t really get to the matter so we can only look at it!

  6. How do we see it all? • Refracting telescopes like Galileo • Reflecting Telescopes • Non-Optical Telescopes

  7. How do we see it all? • Refracting Telescopes • Reflecting Telescopes • Non-Optical Telescopes

  9. Let’s go check it out!

  10. So what did the visible light spectra you saw tell you?

  11. Energy and Matter Interact

  12. Atomic/Molecular Spectra • …But any atom can emit in wavelengths other than visible light!

  13. Atomic/Molecular Spectra • This is all in the visible light spectrum

  14. Spectra can shift!!

  15. Red shift, blue shift, one fish, two fish! Red shift means it’s stretching = away Blue shift means it is compressing = towards

  16. Spectra can be confusing!!! • Spectral emissions/absorptions are directly related to atomic structure, object structure, temperature, and total energy. • BUT spectral lines can shift due to some conditions and be in wavelengths we can’t see. • Computers can help us to sort it all out!

  17. What all can we see? We can see … 1) spectrum or a false color image even if it’s not in the visible light range. 2) The spectrum tells us about the atoms activity and structure 3) Maximum wavelength corresponds with temperature 4) Temperature corresponds with total energy output. 5) The relative motion of the object. Matter and Energy are completely connected! Good for us!

  18. Let’s Take a Look! • …But remember that false-color images can be deceptive!

  22. Let’s Take a Look! X-Ray Infrared Visible Light What can you tell me about the structure of the sun? What’s happening to the matter that makes up the sun?

  23. Can You See My Point?! Questions? Comments? …Dispersions? Can we represent this data in a more holistic way?

  24. Let’s Use It! • Using the spectral data, create a functional illustration on the structure of the sun. • Be sure to include data from all three images and select a complimentary false-coloring scheme that maximizes the usefulness of the illustration you will create.
