Radio astronomy in Australia (1958)

- An explanation of how a radio telescope works, and how two or more radio aerials may be linked together as an "interferometer" to pinpoint more precisely the area from which radio signals are coming.
Several interferometers constructed in Australia between 1946 and 1958 are shown, including the Mills Cross. Their contribution to man's knowledge of radio stars, sunspots, and the extent of our own galaxy, is outlined.

Incredible, a great primer on radio astronomy even in 2018.
Wonderful. I have seen stills of all of the telescopes shown but color movies are so much more informative. I knew that someone moved probes on the Mills cross to change the phasing, but what did they have to do to accomplish that? The film showed it was no harder than plugging into a jack, though I don't envy that walk in the hot Sun. The stick and wire early telescopes have always fascinated me. The number of discoveries made on these modest instruments was astounding.
This is the very earliest work on the sun. Really great film.
Thanks! :)
very interesting.bookmarked for future reference .
Great video. Curious how the pulsar sounds in the first 37 seconds ended up on a 1958 film when they were first discovered in 1967... The abrupt transition to the voice-over (chopping out the word 'radio') at 37 seconds might be a clue to re-dubbing at a later date ?
Very interesting video....
excellent
someone needs to cut the clip about sea interferometry it's awesome

Informative to see how we came to a conclusion that Milkyway is spiral galaxy
I wasnt even born "1958"

Documentaries are better without the modern obsession with constant movement. Today it's endless zooming in and zooming out.
+Walter Scott Agreed.
Spot on. Contemporary science documentaries are nearly unwatchable.
It is the today’s cameramen boredom by the stuff, they do not comprehend but have to bring on film somehow.
They had it back then as well, but it was in its infancy, being pioneered by the Japanese ua-cam.com/video/BdnfWp1WLXE/v-deo.html
Is is these kind of contributions to science from the CSIRO over the years that makes me wonder why the Government keeps cutting the science budget. Still, even with these cuts, it seems that the CSIRO still pushes well above its weight. Surely everyone else sees this.
Science is wonderful!
Somehow this ended up in a playlist of Russian Pavel Klushantsev science-fiction movies about space from 1950s to 1970s. ua-cam.com/video/cmYkpCLuh6I/v-deo.html
