John Bardeen, one of the inventors of key computer technology: Point-contact tansistor, notified AT&T Bell Laboratories that he would be leaving the company along with Walter Brattain and William Shockley. The transistor replaced vacuum tubes, allowing the size of computers to decrease dramatically while their power increased. Bardeen took a position at the University of Illinois at Urbana-Champaign.
On 24 July 1954, James H. Trexler, an engineer in the Radio Countermeasures Branch at the Naval Research Laboratory (NRL), spoke carefully into a microphone at the laboratory's Stump Neck radio antenna facility in Maryland. Two and a half seconds later, his words speeded back to him at Stump Neck, after traveling 500,000 miles via an Earth-Moon circuit. For the first time ever, the sound of a human voice had been transmitted beyond the ionosphere and returned to Earth.
After successfully stepped on the moon, Apollo XI splashed down about 812 nautical miles of the southwest of Hawaii, returning the 3 astronauts safely to Earth. The day before splashdown, Aldrin said, "We feel this stands as a symbol of the insatiable curiousity of all mankind to explore the unknown." It also stands as a tribute to the thousands of engineers, scientists, and others who made the journey possible with their extraordinary efforts.
The first confirmed discovery of extrasolar planets was made in 1992 when a system of terrestrial-mass planets was announced to be present around the millisecond pulsar PSR B1257+12
