Astronomy 101: The Solar System
Lesson 4: Telescopes
Topic: Introduction to Radio Astronomy
Next: Space-Based Telescopes (http://youtu.be/oUFTlt7LJB0)
Previous: Radio Interferometers (http://youtu.be/7gja8u8kDi4)
In Lesson 4, we explore the technologies that astronomers have developed, and continue to develop, to detect light from the universe, at both visible and invisible wavelengths. At visible and near-visible wavelengths, we compare and contrast reflecting and refracting telescope designs, as well as detectors, including spectrographs. We explore why astronomers build bigger and bigger telescopes, and consider both design and atmospheric limitations. We explore technologies that are being developed to overcome atmospheric limitations -- to untwinkle the stars. We also explore how light is detected at radio wavelengths, which can be done from the ground, and at other wavelengths, which requires observing from space. We learn that a great deal can be gained by observing the same object at multiple wavelengths.

Title: Radio Astronomy and Interferometry Fundamentals [Lecture 1/2]
Speaker: David Wilner, Harvard-Smithsonian Center for Astrophysics (dwilner at cfa.harvard.edu)
Date: 2pm (AEDT) Thursday 19th February 2015
Abstract: Radio astronomy uses observations at radio wavelengths to study celestial objects. This lecture will provide a brief introduction to radio astronomy, including a description of common emission mechanisms and radio telescopes, and why multiple telescopes are linked as interferometers to make high resolution “aperture synthesis” images (a technique recognized by the 1974 Nobel Prize in Physics). We will use pictures to develop intuition about the Fourier transform relationship between the sky brightness and visibility function that underlies radio interferometry. (A companion lecture will provide a pedagogical introduction to the process by which radio interferometric images are made.)
Additional Material: Talk slides are available for download at http://goo.gl/VTrFr3.

Radio astronomy is a subfield of astronomy that studies celestial objects at radio frequencies. The initial detection of radio waves from an astronomical object was made in the 1930s, when Karl Jansky observed radiation coming from the Milky Way. Subsequent observations have identified a number of different sources of radio emission. These include stars and galaxies, as well as entirely new classes of objects, such as radio galaxies, quasars, pulsars, and masers. The discovery of the cosmic microwave background radiation, regarded as evidence for the Big Bang theory, was made through radio astronomy.
Radio astronomy is conducted using large radio antennas referred to as radio telescopes, that are either used singularly, or with multiple linked telescopes utilizing the techniques of radio interferometry and aperture synthesis. The use of interferometry allows radio astronomy to achieve high angular resolution, as the resolving power of an interferometer is set by the distance between its components, rather than the size of its components., Enjoy the show, Part 1 -

18-minute documentary about the evolution of Australian radio astronomy from 1939 to when this movie was made in the early 1990s.
Six dishes at Narrabri, one at Coonabarabran, and "The Dish" at Parkes can be hooked up together in such a way as to form a virtual mega-dish with an effective diameter of 300km. This is only possible by perfectly synchronizing the eight signals and by doing complex signal processing (mostly) in real time to filter out random noise. Without such correlation, background noise almost completely masks the weak signal of interest from the distant celestial object under study.
Widely dispersed receiving antennas combining their signals in this way is called Very Long Baseline Interferometry, VLBI for short.
Final scenes show how the detail available in images builds up gradually as vast amounts of data are processed over many hours of observation.
The objects visualized are not identified by name. Neither are the images interpreted by astronomers to explain what scientific discoveries or insights have been gained from them. So we must take it on trust that public expenditure on this sort of pure science really did have a payoff.

In this video, I'm testing the basic setup for my Radio Telescope: a 1420MHz feedhorn, a LNA gain chain with a passband filter, a IC-R7000 as downconverter and my Afedri SDR as a simple spectrum display on the IF output. I'm using a home built noise generator for the test. The output of the generator is VERY weak, around 12dB above thermal noise floor, but it works just fine with all the gain I have in my system.
Sorry for the shakiness - this is shot the 'pragmatic' style, no rehearsal, no list of bullets I need to go through. Just me, my system, my iPhone. That's it! :)
Enjoy

Telescopes have allowed us to look beyond our own solar system and make amazing discoveries. Now a new and exciting period approaches through the development of the world's largest telescope, the Square Kilometre Array (SKA).
So what is the SKA and what does the remote desert of WA have to do with it? We took a cosmic journey back in time as Professor Peter Quinn discussed the power and potential of this new technology to discover and unravel the mysteries of the universe.

This video is designed to explore the surprising utility of radio astronomy as a tool for learning more about the universe. The video's vocabulary and content are tuned for high school students and up. Radio astronomy is a fascinating chunk of physics, because it manages to obtain impressive amounts of data with little more than a telescope which looks like a satellite dish and some math. It also ties serendipitously with discoveries such as dark matter, for reasons which will hopefully be clear within the video.
This video is part of a group of videos produced by ES.333 (Production of Educational Videos). For more information on radio astronomy, see the National Radio Astronomy Observatory's website (https://public.nrao.edu/radioastronomy/what-is-radio-astronomy). If radio astronomy interests you, consider taking Physics Junior Lab, MIT’s 8.13. It’s a tough class but all the data presented in this video was collected there, so it’s well worth it.
Thanks to Graham Ramsay and Dave Custer for their endless patience and aid in bringing this project to fruition, and thanks to Sean Robinson, who advised the script on this project to make sure I kept it grounded in reality. Thank you to Manual Perez de Lema Lopez, for giving me permission to use animations from their simulator program, MTL3D (http://www.mpl3d.com/). And finally thank you to Austin Duffield and the W1MX MIT Radio Society for granting me access to film atop the Green Building.

In Lesson 4, we explore the technologies that astronomers have developed, and continue to develop, to detect light from the universe, at both visible and invisible wavelengths. At visible and near-visible wavelengths, we compare and contrast reflecting and refracting telescope designs, as well as detectors, including spectrographs. We explore why astronomers build bigger and bigger telescopes, and consider both design and atmospheric limitations. We explore technologies that are being developed to overcome atmospheric limitations -- to untwinkle the stars. We also explore how light is detected at radio wavelengths, which can be done from the ground, and at other wavelengths, which requires observing from space. We learn that a great deal can be gained by observing the same object at multiple wavelengths.

Title: Radio Astronomy and Interferometry Fundamentals [Lecture 1/2]
Speaker: David Wilner, Harvard-Smithsonian Center for Astrophysics (dwilner at cfa.harvard.edu)
Date: 2pm (AEDT) Thursday 19th February 2015
Abstract: Radio astronomy uses observations at radio wavelengths to study celestial objects. This lecture will provide a brief introduction to radio astronomy, including a description of common emission mechanisms and radio telescopes, and why multiple telescopes are linked as interferometers to make high resolution “aperture synthesis” images (a technique recognized by the 1974 Nobel Prize in Physics). We will use pictures to develop intuition about the Fourier transform relationship between the sky brightness and visibility function that underlies radio interferometry. (A companion lecture will provide a pedagogical introduction to the process by which radio interferometric images are made.)
Additional Material: Talk slides are available for download at http://goo.gl/VTrFr3.

Radio astronomy is a subfield of astronomy that studies celestial objects at radio frequencies. The initial detection of radio waves from an astronomical object was made in the 1930s, when Karl Jansky observed radiation coming from the Milky Way. Subsequent observations have identified a number of different sources of radio emission. These include stars and galaxies, as well as entirely new classes of objects, such as radio galaxies, quasars, pulsars, and masers. The discovery of the cosmic microwave background radiation, regarded as evidence for the Big Bang theory, was made through radio astronomy.
Radio astronomy is conducted using large radio antennas referred to as radio telescopes, that are either used singularly, or with multiple linked telescopes utilizing the techniques of radio interferometry and aperture synthesis. The use of interferometry allows radio astronomy to achieve high angular resolution, as the resolving power of an interferometer is set by the distance between its components, rather than the size of its components., Enjoy the show, Part 1 -

18-minute documentary about the evolution of Australian radio astronomy from 1939 to when this movie was made in the early 1990s.
Six dishes at Narrabri, one at Coonabarabran, and "The Dish" at Parkes can be hooked up together in such a way as to form a virtual mega-dish with an effective diameter of 300km. This is only possible by perfectly synchronizing the eight signals and by doing complex signal processing (mostly) in real time to filter out random noise. Without such correlation, background noise almost completely masks the weak signal of interest from the distant celestial object under study.
Widely dispersed receiving antennas combining their signals in this way is called Very Long Baseline Interferometry, VLBI for short.
Final scenes show how the detail available in images builds up gradually as vast amounts of data are processed over many hours of observation.
The objects visualized are not identified by name. Neither are the images interpreted by astronomers to explain what scientific discoveries or insights have been gained from them. So we must take it on trust that public expenditure on this sort of pure science really did have a payoff.

In this video, I'm testing the basic setup for my Radio Telescope: a 1420MHz feedhorn, a LNA gain chain with a passband filter, a IC-R7000 as downconverter and my Afedri SDR as a simple spectrum display on the IF output. I'm using a home built noise generator for the test. The output of the generator is VERY weak, around 12dB above thermal noise floor, but it works just fine with all the gain I have in my system.
Sorry for the shakiness - this is shot the 'pragmatic' style, no rehearsal, no list of bullets I need to go through. Just me, my system, my iPhone. That's it! :)

Produced by Danny Ben-David; created May 4, 2015
This video is designed to explore the surprising utility of radio astronomy as a tool for learning more about the universe. The video's vocabulary and content are tuned for high school students and up. Radio astronomy is a fascinating chunk of physics, because it manages to obtain impressive amounts of data with little more than a telescope which looks like a satellite dish and some math. It also ties serendipitously with discoveries such as dark matter, for reasons which will hopefully be clear within the video.
This video is part of a group of videos produced by ES.333 (Production of Educational Videos). For more information on radio astronomy, see the National Radio Astronomy Observatory's website (https://public.nrao.edu/radioastronomy/what-is-radio-astronomy). If radio astronomy interests you, consider taking Physics Junior Lab, MIT’s 8.13. It’s a tough class but all the data presented in this video was collected there, so it’s well worth it.
Thanks to Graham Ramsay and Dave Custer for their endless patience and aid in bringing this project to fruition, and thanks to Sean Robinson, who advised the script on this project to make sure I kept it grounded in reality. Thank you to Manual Perez de Lema Lopez, for giving me permission to use animations from their simulator program, MTL3D (http://www.mpl3d.com/). And finally thank you to Austin Duffield and the W1MX MIT Radio Society for granting me access to film atop the Green Building.
