- - - - The Hubble Space Telescope is 2400 mm Ritchey Chretien telescope with about a half dozen instruments. It is capable of long exposures of various objects using its imaging cameras as well as a wide array of photometric data like spectography. In a sense, it is much like many ground-based telescopes in that it's a fairly versatile instrument.
    - - Kepler is a 950mm Schmidt Camera with an array of 42 imaging sensors providing an overall resolution of 95 megapixels. It is designed not to take pictures, but to produce photometric data of the brightness
      - Kepler has a single mission: monitor a single patch of the sky and measure the brightness of all the stars in that patch. that data is returned to earth where comparisons are made between measurements to determine changes in the light curves over time that might be caused by planets.
      - Kepler also orbits the sun, not the Earth, while Hubble orbits the Earth.
- - - - In the Chinese and rest of the world's eyes: THE NANKING MASSACRE
        In 1928, the Chinese Nationalist Government moved the capital of China from Peking to Nanking. The city normally held about 250,000 people, but by the mid-1930's its population had swollen to more than 1 million. Many of them were refugees, fleeing from the Japanese armies which had invaded China since 1931. On November 11, 1937, after securing control of Shanghai, the Japanese army advanced towards Nanking from different directions. In early December, the Japanese troops were already in the proximity of Nanking.
      - On December 9, after unsuccessfully demanding the defending Chinese troops in Nanking to surrender, the Japanese troops launched a massive attack upon the city. On the 12th, the defending Chinese troops decided to retreat to the other side of Yangtze River. On the 13th of December, the 6th and the 116th Divisions of the Japanese Army first entered the city. At the same time, the 9th Division entered Guanghua Gate, and the 16th Division entered Zhongshan Gate and the Pacific Gate. In the afternoon, two Japanese Navy fleets arrived on both sides of the Yangtze River. On the same day, December 13th, 1937, Nanking fell to the Japanese. In the next six weeks, the Japanese committed the infamous Nanking Massacre, or the Rape of Nanking, during which an estimated 300,000 Chinese soldiers and civilians were killed, and 20,000 women were raped.
      - During the Nanking Massacre, the Japanese committed a litany of atrocities against innocent civilians, including mass execution, raping, looting, and burning. It is impossible to keep a detailed account of all of these crimes. However, from the scale and the nature of these crimes as documented by survivors and the diaries of the Japanese militarists, the chilling evidence of this historical tragedy is indisputable.
