International Year of Astronomy - Significance of 1609

Significance of 1609

In 1609, Galileo Galilei first turned one of his telescopes to the night sky and made astounding discoveries that changed mankind's conception of the world forever: mountains and craters on the Moon, a plethora of stars invisible to the naked eye, and moons around Jupiter. Astronomical observatories around the world promised to reveal how planets and stars are formed, how galaxies assemble and evolve, and what the structure and shape of our Universe actually are. In the same year, Johannes Kepler published his work Astronomia nova, in which he described the fundamental laws of planetary motions.

On 25 September 1608, Hans Lippershey, a young man from Middelburg, travelled to the Hague, the then capital of the Netherlands, to demonstrate one of his inventions to the Dutch government: the telescope. Although Hans was not awarded the patent, Galileo heard of this story and decided to use the "Dutch perspective glass" and point it towards the heavens.

Famous quotes containing the words significance of and/or significance:

    Politics is not an end, but a means. It is not a product, but a process. It is the art of government. Like other values it has its counterfeits. So much emphasis has been placed upon the false that the significance of the true has been obscured and politics has come to convey the meaning of crafty and cunning selfishness, instead of candid and sincere service.
    Calvin Coolidge (1872–1933)

    The hysterical find too much significance in things. The depressed find too little.
    Mason Cooley (b. 1927)
