B efore the invention of telescopes, the sky and celestial bodies were studied through the naked eye only. The invention of telescope has widened the scope of space stud- ies. Several great astronomers have also helped study new phenomena related to space. Famous Astronomers

Edwin Hubble Edwin Hubble was an American astronomer. He con- tributed greatly to the field of modern astronomy . He formulated Hubble’s law. This law states that the galaxies are moving away from each other at a fixed rate. This rate is equal to the distance between the moving galaxies. He also found a method to clas- sify different galaxies. In 1929, he proved that the universe is expanding. A hugely important space telescope (below) is named for him.
