3D presentation of Milky Way galaxy dates back to third century B.C.
The word galaxy is derived from the Greek galaxias, literally “milky”, a reference to the Milky Way . Galaxies contain varying numbers of planets, star systems, star clusters and types of interstellar clouds. Archimedes, known for important discoveries in astronomy, constructed a bronze planetarium in which the earth and heavenly bodies all moved in their orbitswhen a crank was turned. Unfortunately for Archimedes there are probably more than 170 billion galaxies in the observable universe. Can you help him to study to this one by separating the parts and joining them back to starting position?
