Astronomy is the science that studies the universe.

Ptolemy 140 CE, Greek wrote the first Astronomy textbook “Geocentric” model “epicycles” His ideas lasted 1400 years

Ptolemy epicycles

Copernicus , Polish f/f2/Nikolaus_Kopernikus.jpg sun First to suggest “heliocentric” model – sun is center of universe

What do you think? Why do you think it was difficult for people to accept a heliocentric model (sun centered) over the geocentric model (Earth centered)? Why do you think it was difficult for people to accept a heliocentric model (sun centered) over the geocentric model (Earth centered)? Geocentric modelHeliocentric model

Copernicus

Tycho Brahe 1546 – 1601, Danish /commons/2/2b/Tycho_Brahe.JPG detailed observations and measurements – tracked orbits

Tycho Brahe his ideas combined both geo and heliocentric models  sun & moon revolved around the Earth.  other planets revolve around the sun. tycho

Johannes Kepler kepler 1571 – 1630, German assistant to Tycho Brahe supported heliocentric model

Johannes Kepler Three Laws of Planetary motion 1.Planets have elliptical orbits 2.Speed of a planet changes during its orbit [ 3. Law of harmonies]

Galileo Galilei lileiGalileo-Cresti300px.jpg , Italy “The Father of Modern Science” supported heliocentric model

Galileo Galilei sunspots Venus had phases four of Jupiter’s moons 1609 developed a telescope to study objects in the sky moon’s surface was not smooth

lileiGalileo-Cresti300px.jpg Galileo

Isaac Newton , England 1687 Published book on laws of motion Newton’s Laws explained Kepler’s theories about orbital ellipses of the planets and the motion of the universe

Isaac Newton Universal Law of Gravitation The force of gravity depends on the mass of the objects and the distance between them

Isaac Newton Universal Law of Gravitation sir-isaac-newtons-law-of-gravity

Edwin Hubble , USA discovered that other galaxies existed beyond the Milky Way proved the universe is expanding support Big Bang Theory
