Galileo
/
Galileo Galilei was an Italian polymath. Galileo is a central figure in the transition from natural philosophy to modern science and in the transformation of the scientific Renaissance into a scientific revolution.
Newton, Isaac

Hubble, Edwin

Ursa major
/Ursa Major is a constellation in the northern sky, whose associated mythology likely dates back into prehistory. Its Latin name means “greater she-bear”, standing as a reference to and in direct contrast with nearby Ursa Minor, the lesser bear.
