Neil Armstrong
Neil Alden Armstrong (August 5, 1930 – August 25, 2012) was an American astronaut and aeronautical engineer who became the first person to walk on the Moon in 1969. He was also a naval aviator, test pilot, and university professor. Armstrong was born and raised in Wapakoneta, Ohio. A graduate of Purdue University, he studied aeronautical engineering; his college tuition was paid for by the U.S. Navy under the Holloway Plan. He became a midshipman in 1949 and a naval aviator the following year. He saw action in the Korean War, flying the Grumman F9F Panther from the aircraft carrier . In September 1951, while making a low bombing run, Armstrong's aircraft was damaged when it collided with an anti-aircraft cable, strung across a valley, which cut off a large portion of one wing. Armstrong was forced to bail out. After the war, he completed his bachelor's degree at Purdue and became a test pilot at the National Advisory Committee for Aeronautics (NACA) High-Speed ...

Google Doodle
A Google Doodle is a special, temporary alteration of the logo on Google's homepages intended to commemorate holidays, events, achievements, and notable historical figures. The first Google Doodle honored the 1998 edition of the long-running annual Burning Man event in Black Rock City, Nevada, and was designed by co-founders Larry Page and Sergey Brin to notify users of their absence in case the servers crashed. Early Marketing employee Susan Wojcicki then spearheaded subsequent Doodles, including an alien landing on Google and additional custom logos for major holidays. Google Doodles were designed by an outside contractor until 2000, when Page and Brin asked public relations officer Dennis Hwang to design a logo for Bastille Day. Since then, a team of employees called "Doodlers" have organized and published the Doodles. Initially, Doodles were neither animated nor hyperlinked—they were simply images with tooltips describing the subject or expressing a holiday gree ...

Apollo 11
Apollo 11 (July 16–24, 1969) was the American spaceflight that first landed humans on the Moon. Commander Neil Armstrong and lunar module pilot Buzz Aldrin landed the Apollo Lunar Module ''Eagle'' on July 20, 1969, at 20:17 UTC, and Armstrong became the first person to step onto the Moon's surface six hours and 39 minutes later, on July 21 at 02:56 UTC. Aldrin joined him 19 minutes later, and they spent about two and a quarter hours together exploring the site they had named Tranquility Base upon landing. Armstrong and Aldrin collected of lunar material to bring back to Earth as pilot Michael Collins flew the Command Module ''Columbia'' in lunar orbit, and were on the Moon's surface for 21 hours, 36 minutes before lifting off to rejoin ''Columbia''. Apollo 11 was launched by a Saturn V rocket from Kennedy Space Center on Merritt Island, Florida, on July 16 at 13:32 UTC, and it was the fifth crewed mission of NASA's Apollo program.

Faint Young Sun Paradox
The faint young Sun paradox or faint young Sun problem describes the apparent contradiction between observations of liquid water early in Earth's history and the astrophysical expectation that the Sun's output would be only 70 percent as intense during that epoch as it is during the modern epoch. The paradox is this: with the young sun's output at only 70 percent of its current output, early Earth would be expected to be completely frozenbut early Earth seems to have had liquid water and supported life. The issue was raised by astronomers Carl Sagan and George Mullen in 1972. Proposed resolutions of this paradox have taken into account greenhouse effects, changes to planetary albedo, astrophysical influences, or combinations of these suggestions. It turned out that the greenhouse gas carbon dioxide contributed most. Solar evolution Models of stellar structure, esp. the standard solar model were already sufficiently evolved at that time to predict a brightening: It is due to th ...

Alastair G
Alistair is a masculine given name. It is an Anglicised form of the Scottish Gaelic '' Alasdair''. The latter is most likely a Scottish Gaelic variant of the Norman French Alexandre or Latin Alexander, which was incorporated into English in the same form as Alexander. The deepest etymology is the Greek Ἀλέξανδρος (man-repeller): ἀλέξω (repel) + ἀνήρ (man), "the one who repels men", a warrior name. Another, not nearly so common, Anglicization of ''Alasdair'' is ''Allaster''. Hanks; Hardcastle; Hodges (2006) p. 399.
