It is a bit difficult to state in just a few sentences. Hubble has measured the age and size of the Universe better than before (by refining value for the Hubble constant – or the expansion rate). It has also seen details in the first galaxies that are not visible from the ground. Today we know that galaxies were formed earlier than previously thought and most scientists also believe that they evolve by colliding and merging together.
