Did you know that in many countries, including Russia and Ukraine, Christmas is celebrated on January 7 and not December 25? This is because according to the Julian calendar used by the Russian Orthodox Church, Christmas falls on this day. The celebrations begin on December 31 and end on January 10.
January 7 is also the day on which Italian astronomer Galileo Galilei discovered Galileo's moons. This was in 1610. He discovered that four moons revolve around Jupiter and that the telescope reveals many more stars than are visible to the naked eye. The moons are now called Io, Europa, Ganymede and Callisto. They were believed to be the first celestial objects to orbit a planet other than the Earth. Galileo, was an astronomer, physicist and engineer and is often called the "father" of observational astronomy, modern physics, the scientific method and modern science.
