1930: Pluto discovered
Clyde Tombaugh, 24, discovered a new planet today, eventually named Pluto after the Greek god of the underworld. Tombaugh located the planet while in the dome of the observatory in Flagstaff, Arizona, where he worked as a ‘sky watcher’ and made photographic plates. He discovered Pluto by looking at the plates through the Blink microscope comparator, which was used to compare the plates in search of moving objects. Tombaugh, who, at the time had not yet graduated from college, was the first (and only) United States citizen to discover a planet.
“He accomplished what other astronomers had been trying for since 1905, when the late Percival Lowell proposed that irregularities in the orbit of Uranus indicated the presence of another planet in the sky,” reported the Northwest Arkansas Times on September 23, 1964.
NOTE: Pluto remained a designated planet for 76 years until August of 2006 when the International Astronomical Union defined the word ‘planet’ for the first time. This definition excluded Pluto and reclassified it as a dwarf planet.

In International News:
- Three men were arrested on Tuesday for plotting to assassinate Kurt Westergaard, the Danish cartoonist who drew the Bomb in the Turban cartoon which sparked outrage when first published in 2005.

Muslims in the Gaza Strip, Pakistan and Denmark protested the reprinting, which depicts the prophet Muhammad with a bomb in his turban. The case is a striking example of religious respect versus free speech.
