Window of Universe: Astronomy: Window of Universe - Karl Jansky-KARL JANSKY'S STATIC FROM SPACE
KARL JANSKY'S STATIC FROM SPACE
In 1928, just a year after graduating from the University of Wisconsin, radio engineer Karl jansky (1905-50) accepted a job with Bell Telephone Laboratories.
One of his first assignments was to track down the source of static that interfered with radio reception and ship-to-shore communications.

Voyager: Astronomy: Voyager - SOLAR PROBES
SOLAR PROBES
Ulysses, a joint mission by NASA and the European Space Agency (ESA) to study the Sun's environment and the solar wind, was launched in October 1990. This was the first time a spacecraft had been deliberately sent out of the ecliptic (the plane of the Solar System). After receiving a gravity assist from Jupiter in February 1992, the Ulysses probe went on to pass over the Sun's south pole in May 1994, then over its north pole a year later.

Voyager: Astronomy: Voyager - GALILEO
GALILEO
Intrigued by the Voyager findings at Jupiter, planetary scientists once again turned their attention toward that planet in the early 1980s. They designed a mission to orbit Jupiter and monitor the planet and its satellites for at least two years. In addition, a probe was to be deployed from the spacecraft into Jupiter's atmosphere.

Voyager: Astronomy: Voyager - COMET MISSIONS
COMET MISSIONS
Although the planets have usually been the destinations of space probes, minor members of the Solar System have not been ignored. In March 1986, several space probes passed near Bailey's Comet as it approached Earth.

Voyager: Astronomy: Voyager - VOYAGER AND BEYOND
VOYAGER AND BEYOND
In March 1979, Voyager 1 flew past Jupiter, sending back thousands of high-resolution photos of the cloud tops as well as intriguingly detailed images of the moons
Callisto, Ganymede, Europa, and lo. Jupiter's gravity gave
Voyager 1 the velocity needed to reach its ultimate destination,
Saturn, in November 1980.
