  1. Comet ISON An illustration of Science in action….

  2. Comet ISON • Processes involved in Good Science? • Illustrations of these following Comet ISON’s detection, approach, and orbiting of the Sun

  3. Processes involved in science: • observation of data, developing questions about trends, differences, unique occurrences seen within that data, • research into previous work on similar questions, • building models & creating testable hypotheses, • designing & gathering new data through, experiments, • testing & refining models based on analysis of new data

  4. Processes involved in science: • modifying or discarding incorrect hypotheses • developing interconnected hypotheses into theories • sharing data & results with peers for independent evaluation and testingand • publishing findings in peer-reviewed journals so that the community of science can advance.

  5. Obsevations: • Detected Sept 21, 2012 • Confirmed by others AND by looking at earlier photos by 9/24 Good Science: Multiple independent observations

  6. Observations • Very “active” for so far away. SWIFT Gamma Ray Telescope (launched 2004) Deep Impact Mission (launched 2005) Good Science: Look at objects with multiple wavelengths, in different ways, to learn more

  7. Models: • Orbit model of a “Sungrazer Comet” • Like 1680 Comet Kirch? Good Science: Research past similar orbits and trajectories, develop models based on data plus earlier knowledge

  8. Develop Hypotheses • Very “active” => Might it create a great sight? Would it look like Comet Hartley ? Good Science: Research past comets

  9. Develop Hypotheses • New comet, fresh from Oort cloud • Like 2011 Comet Lovejoy Good Science: Develop Hypotheses based on available data, suggest tests for these to spur new observations/experiments

  10. Develop Hypotheses • New comet, fresh from Oort cloud • Like 2011 Comet Lovejoy, would it survive? Good Science: Develop Hypotheses based on available data, suggest tests for these to spur new observations/experiments

  11. Develop Hypotheses • It could be an epic failure • It could fizzle & burn up • It could be spectacular!

  12. Testing of Hypotheses w/ multiple experiments

  13. Testing of Hypotheses w/ multiple experiments Why so active so early? Use IR telescope to see CO2 & CO molecules ISON has lots of Gas! “The Soda Pop Comet”

  14. Testing of Hypotheses w/ multiple experiments Use spectra to help confirm composition

  15. Refining Models • Involve lots of scientists Good Science: Sharing different views and ideas among peers advances science

  16. Testing of Hypotheses w/ multiple experiments Continued study – it might be really SPECTACULAR!

  17. Discarding Hypotheses based on new data
