Edwin Hubble lived from November 20, 1889 to September 28, 1953, a time where astronomy and such was just getting popular and space exploration was just beginning. He is credited with many discoveries, such as the idea that the universe extends beyond the Milky Way, probably his most impacting discovery. In addition to seeing that the universe was vastly larger than previously noted, Edwin Hubble also discovered that other galaxies and celestial bodies were constantly moving at rates calculable with what is now called “Hubble’s Law”. His discoveries also led to the eventual (possible) calculation of the Big Bang Theory, which was calculable by finding the source/center of all the moving galaxies and their various rates in relation to each other.
He also discovered an asteroid, named “asteroid 1373 Cincinnati”, in August of 1935 in addition to writing a book on observational astronomy (mostly naked eye and some telescopic) and a book about nebulae. He spent a lot of his later years pushing for astronomy to be considered in the physics sector of the Nobel Prize, and shortly after his death, the Nobel Prize committee decided that work in the astronomical field could be considered for the physics prize. The current telescope, from which so many fascinating and mind-blowing pictures come from, The Hubble Space Telescope, was named after Edwin and his passion for astronomy.

On July 31, 1999, Lunar Prospector crashed into the Moon. During its successful 1 year mission to map the Moon's global properties from orbit, Lunar Prospector confirmed indications that water-ice could be trapped in permanently shadowed craters near the lunar poles. Its mission complete, controllers intentionally targeted the spacecraft to impact a crater wall, hoping that water could be more directly detected in the resulting debris cloud - although the chances of a successful detection were considered low. Astronomers analyzing the data recently announced that no visible signature of water was found, so the tantalizing case forwater on the Moon remains open."
