A Quote by Honor Harger
Radio astronomers study radio waves from space using sensitive antennas and receivers, which give them precise information about what an astronomical object is and where it is in our night sky. And just like the signals that we send and receive here on Earth, we can convert these transmissions into sound using simple analog techniques.

Radio astronomers are aware in the back of their minds that if there are other civilizations out there in space, it might be the radio astronomers who first pick up the signal.
Give consideration to the fact that alien astronomers could have scrutinized Earth for more than 4 billion years without detecting any radio signals, despite the fact that our world is the poster child for habitability.
Radio astronomy reflects our fascination with how audio can be used to understand information or ideas. Just as scientists visualize data through charts and pictures, we can use 'data sonification' to translate radio signals into sound that help us better understand some of our most enigmatic planetary systems.
It's quiet. No cars. No birds. Nothing.' 'No radio waves,' said the Doctor. 'Not even Radio Four.' 'You can hear radio waves?' 'Of course not. Nobody can hear radio waves,' he said unconvincingly.
The strongest signals leaking off our planet are radar transmissions, not television or radio. The most powerful radars, such as the one mounted on the Arecibo telescope (used to study the ionosphere and map asteroids) could be detected with a similarly sized antenna at a distance of nearly 1,000 light-years.
Each of is endlessly generating waves with our actions. If you could see the earth from a vibratory point of view, you would see something like radio waves billions of them, cascading constantly into very complex patterns all over the earth.
A radio telescope pointing at the sky receives radiation not only from space, but also from other sources including the ground, the earth's atmosphere, and the components of the radio telescope itself.
As far as the radio waves part of the spectrum, we can do these adequately from the ground because the atmosphere is basically transparent to our radio waves.
In the field of astronomy in the mid-'60s, quasars were very sexy objects - gigantic, star-like masses about which little was known. I was a graduate research student at Cambridge working towards my Ph.D. and chose quasars as the subject for my thesis. Part of my project involved surveying the sky for them using a radio telescope.
It wasn't just about flashing lights and pinball machines blowing up and things like that. It was about using encores, bringing back the good songs and using techniques that I knew about from rock performance.
The further conquest of space will make it possible, for example, to create systems of satellites making daily revolutions around our planet at an altitude of some 40,000 kilometers, and to assure universal communications and the relaying of radio and television transmissions. Such an arrangement might prove more useful, economically, than the construction of radio relay systems over the whole surface of the earth. The great accuracy of movement of these satellites will provide a reliable basis for solving navigational problems
There is no line of demarcation between the amateurs and the pros; everyone is using the same tactics and playing in the same arenas. The only thing that separates them is radio, but the artist doesn't control who goes to radio and who doesn't.
The program is a voyage chart, a series of signals, which, like the pilot's radio, provides the basic orienting information required for the trip.
Ever since the Second World War, television signals (as well as FM radio and radar) have served as Homo sapiens' emissaries into deep space. High-frequency, high-power broadcasts have filled an Earth-centered bubble more than 60 light-years in radius with signals.
Radio or no radio, I just like the way records sound when the drums and vocals are loud.
I went in, and there, in the front room, a converted bedroom, sat the first radio I had ever seen. The equipment was so bulky that it took up one entire wall of the bedroom. The set, which could send or receive signals, was tuned to KDKA in Pittsburgh, and I remember being completely flabbergasted at the thought of sounds coming from that box.
