Presentation transcript:

Notes  Using the following power point slides, take notes on notebook paper.  You should write everything/answer the questions in your notes.  If you do not know the answers to the question, you will need to search for it on Internet.  Video clip links are not working. You will see them at some point during class.  Other underlined links work and you may explore them.

Astronomy OR Astrology  What’s the difference? AstronomyAstrology

Electromagnetic Radiation  Energy that travels through space (in the form of waves)

 List 4 types of electromagnetic radiation.  What type of radiation can we see?

Astronomy Tools

Telescopes

Telescopes Refracting (uses lenses) Reflecting (uses mirrors)

Telescopes Radio

 Do NOT listen to “noises” or sounds  Records different amounts of radio emissions coming from objects and uses computers to create an image Images

Observatories  Building with one or more telescopes  Why are they located on mountaintops?

Telescopes in Space  Launched in April 1990 onboard the space shuttle Discovery  Cost - $2.5 billion  Takes high quality pictures of the universe  Will remain active until Hubble Telescope

Spectrographs  Breaks light into colors  Provides information on star chemical composition and temperature

Rockets  What causes rockets to move forward?  What happens when a “stage” uses up its fuel? “stage” uses up its fuel?  What did the development of the multistage rocket make possible? History Apollo Saturn V

Newton’s 3 rd Law of Motion  For every action, there is an equal and opposite reaction.

Satellites – natural or artificial object that revolves around an object in space  What does it mean when a satellite is in a “geosynchronous orbit”?  What are satellites used for?

Space Probes Mariner Cassini Voyager  What is the difference between a satellite and a space probe?

Space Shuttle

Space Shuttles  Reusable  Land back on Earth like airplanes  Why are they covered in insulated tiles? The Space Shuttle The Space Shuttle 2 Challenger Disaster Living Weightlessness Jet Packs

Space Station  Large satellite in which people can live for long periods of time ISS Website CountriesArriving at ISS Where is the ISS?
