Understanding Radio Telescopes: Dr John Morgan

Curtin University "Super Fellow" John Morgan explains what how radio telescopes are an essential tool for looking into the mysteries of the universe. He talks about the awesome Square Kilometre Array, and the role of Curtin know-how in creating the associated Murchison Widefield Array.
This lecture was held on Wednesday 27 August 2014.

ICRAR: Discovering the hidden Universe through radio astronomy

[jackdoe]

As a would-be amateur radio astronomer, this is the best introduction I've found. Complex concepts made clear to the layperson. Great presentation all around.

[AwakeInAnacortes]

This is one of the best youtube vids on radio astronomy. Thank you for sharing with us!

[JAGzilla-urlh]

I've never been clear on how a radio telescope works and I've tried watching a few other videos that explain it. They completely failed to get through to me. This lecture did the trick, though! Excellent presentation by a top tier speaker. Thanks for the info!

[SeahawkSailor]

Great presentation. I was very curious about, and happy to learn how the detector works. Thanks to this video, 18 yrs after this lecture, on the other side of the world (US east coast), I have learned quite a bit. Thank you.

I am an amateur radio operator, as well as an aspiring amateur radio astronomer, and I get my information from the NASA radio Jove website. I am more interested in emissions from the planet Jupiter as they are actually kind of cool sounding, and creepy sounding at the same time.

Is there anyone in the audience?
I never saw the camera EVER look at the audience. The applause sounds just like the the TV.

I'm here because I'm reading Contact, by Carl Sagan :)

[jefflucas_life]

NOt one word how EM are converted to viewable imagery, exactly what is the application used to image radio waves?

[Ravan_R]

Awesome explanation. Really the best. Thank you.

[hymanmj]

That was a superb watch. Complex concepts made easy(ish!). Thank you. :)

The sound of the static on the radio is quite relaxing

With three, you can triangulate to an image with a parabolic reflector. At the focal plane.

The Operational Amplifier, or Instrument Amplifier design, eliminates that hiss caused by the circuitry utilizing Common Mode Rejection. We need to redesign these clear through to utilize the highest frequency response transistors available, and use factors of gain controlled stage per stage, with Common Mode Rejection Available, stage per stage with tunable RF Equalizer, for RF, not audio band. Each stage a linear amp of that said detail.

I'm here because i live in Parkes, NSW. We have Big Radio Telescope 🔭😇

[AstroRoxy]

Never knew that MWA was built by students, definitely something to try

Does anyone know if Radio Telescopes can detect pH of an environment?

[qzorn]

In trying to learn radio telescopes the info goes from million dollar projects to out of the junk room stuff. 😎 Need some ebay out of the box radio-astronomy hobby kits for quick results.

[TheFuzzyTomcat]

This guy is the model of a typical werewolf.

Wonder why he likes astronomy so much...

[debradaugherty]

All extrasolar information is electromagnetic? What about cosmic rays and neutrinos?

[MODGNAR]

I am here because China's FAST is about to turn on.
