1877

Sir James Jeans (1877-1946) was born in London. In his lifetime, this mathematician, physicist, and astronomer would teach at Cambridge and Princeton. Jeans would also study radiation and the stars, including their energy and different types of stars and star systems. He disproved Laplace's nebular hypothesis and supported Thomas C. Chamberlin's catastrophic theory; saying that the planets were formed by the condensing of stellar debris, rather than from a 'single gaseous cloud'. For those interested, Jeans' books are listed here.

1941

Shortly before the Japanese attack on Pearl Harbor in a speech in Des Moines, Iowa, great American aviator and, at this time, an isolationist, Charles Lindbergh names three groups he believes are pushing the U.S. to enter the war: "the British, the Jewish, and the Roosevelt Administration."

1967

Launched just three days before, the Surveyor 5 spacecraft lands on the moon, conducts a variety of experiments and sends images back to Earth. In this first lunar day, Surveyor had sent back 18,000 pictures, and 83 hours worth of data on the composition of the moon's soil.

1985

The International Cometary Explorer (ICE) was a repurposed mission - originally the Sun-Earth Explorer-3. When ICE flew by the comet Giacobini-Zinner in 1985, it became the first spacecraft to pass a comet. Learn more about the Giacobini-Zinner comet here:
