Astronomy ? INTRODUCTION TO ASTRONOMY Literally: aster = star + nomie = naming Greek words for “star law” (Astrology was already taken)

What are you expected to know Measurements used in astronomy  Significant figures  Scientific notation  Dimensional analysis vocabulary used in astronomy Lots of them History of astronomy  Ancient astronomy  Modern astronomy Formation and Structure of the universe  Earth and Moon  Solar system  Constellations  Galaxies Discovery of the night sky  Gravity  Light and telescopes  Classifying celestial bodies  Exploration

Ever wonder How can this ? hydrogen Turn into this and into this… And then into this…..

A promise and a warning The promise: – You will learn a lot. The warning: – Each lecture builds on material from earlier lectures, so it’s easy to fall behind and hard to catch up again.

Astronomy - the branch of science that deals with celestial objects, space, and the physical universe as a whole. celestial -beyond the earth's atmosphere

Astronomers who just finished a PhD will make 35,000$ to 55,000$ their first 5 or so years doing postdoctoral research appointments Astronomer-scientist who studies celestial bodies Astronomers who make the most have published works. (books, video..) This guy made “millions and millions” Carl Sagan R.I.P.

Astrologists make an average annual salary of 42,000 $ Susan Miller This woman makes so much $$ you can’t even find out how much online…… Astrology is NOT a “true” Science but you can make real money from it astrologist - someone who predicts the future by the positions of the planets and sun and Moon

Astrophysics - the physics of the universe (Astrophysicist ? (Astrophysicist ? $51,670 to $170,230 )

Astrobiology – studies the advent and evolution of biological systems in the universe. (astrobiologist? ) Astrobiology – studies the advent and evolution of biological systems in the universe. (astrobiologist? $55,760 to $83,640 )
