What are radio telescopes used for for kids?
A radio telescope is a type of antenna, like a huge satellite television dish. It is used for radio astronomy. Stars shine and the light can be seen with an ordinary telescope, but they also give off radio waves. Scientists with radio telescopes receive these radio waves and use computers to learn about the stars.
What did the Parkes radio telescope discover?
Astronomers discovered the Magellanic Stream using Parkes radio telescope in 1973. This is a huge cloud of gas arching around our own Milky Way galaxy. The stream is 300,000 light-years long. Researchers think is is the result of an interaction between two dwarf galaxies and the Milky Way.
What does the radio telescope at Parkes do?
The Parkes radio telescope is a gigantic measuring instrument, used to examine a wide range of radio energies from our galaxy and other parts of the universe. Objects such as pulsars, galaxies and quasars broadcast enormous quantities of radio energy into space.
Why is the Parkes radio telescope famous?
The Parkes radio telescope has become an icon and a symbol of Australian ingenuity. It is the subject of numerous photographs, was the subject of a blockbuster movie, The Dish, and played a key role in televising images of the Apollo 11 Moon landing on 20 July 1969. And that’s before we even get to the science.

In a side yard of his mother’s house in Wheaton, Illinois, a 26-year old engineer named Grote Reber built the first dish antenna radio telescope in 1937.
Who is the father of radio astronomy?
Karl Guthe Jansky
Radio telescope/Inventors
Far more people have heard of the film than of the man for whom that observatory is named: Karl Guthe Jansky, known among astronomers as the father of radio astronomy. Born in 1905, Jansky was one of six children.
Who built the Parkes telescope?
CSIRO
Half of the more than 2000 known pulsars have been found using the Parkes telescope. The introduction of a multibeam receiver, a revolutionary instrument designed and built by CSIRO, enabled Parkes to be used for large-scale surveys of the sky.
