Castalia . Asteroid 4769 . Asteroid 4769 Castalia is a near-Earth crossing asteroid that was discovered by Eleanor F. Helin (Caltech) on August 9, 1989. Scientists used radio astronomy and computer modeling to generate this image of Castalia. They obtained the data for the computer model in 1989 using the Arecibo radar/radio telescope in Puerto Rico when the asteroid passed within 5.6 million kilometers (3.5 million miles) of the Earth. ...

The radio-telescope. The radio-telescopes are the great sized constructions. The most spread type of the radio-telescope is a construction the basic element of which is a whole metallic mirror of a parabolic form. The mirror reflects the radiowaves falling on it, so they gather near the focus and are able to be caught by the special unit- irradiator. Then the signal is strengthened and changed into the form convenient for a registration and analysis. ... Back . ...
