17TH CENTURY
Using a telescope, Galileo Galilei makes
important findings about the moons of
Jupiter and the phases of Venus.

LATE 17TH CENTURY


With the publication of his theories of
motion and universal gravitation, Isaac
Newton offers a thorough justification
for the motion of the stars.

19TH CENTURY
Major advances in the study of double
stars and the skies of the southern
hemisphere are made by Sir John
Herschel.

20TH CENTURY
The knowledge gained from Edwin
Hubble's observations is that the universe
