AI Thread Summary
The discussion centers on whether cosmic electromagnetic radiation follows Gaussian characteristics or if it is uniformly distributed across wavelengths. Participants express curiosity about the existence of low noise areas in the electromagnetic spectrum, particularly in relation to the search for extraterrestrial intelligence (SETI). There is also a question regarding how instruments convert electromagnetic vibrations into sound, especially given the blackbody spectrum at approximately 3 degrees Kelvin. The idea of focusing SETI efforts on low noise regions is proposed as a strategy for clearer communication. Overall, the conversation highlights the complexities of cosmic electromagnetic radiation and its implications for scientific research.

Hi,

Does the cosmic electromagnetic emitters, if viewed in the function of electromagnetic intensity and in the particular wave length, follow the gaussian characteristics or is the noise uniformly distributed over all wavelengths? I.e. is there "tranquility" in intensity (or least amount of noise) in particular area of electromagnetic radiation in the universe?

Thanks!

I actually wonder the same thing!

What i also don't understand is how the instruments in space can "convert" the electromagnetic vibrations from the object into sound ?
 
its a blackbody spectrum at about 3 degrees kelvin.
 
Hi guys,

Well the reason I asked is that I was wondering one day if the SETI-project is concentrating these low noise areas (if there are any of course). I mean If was to get a message heard I would rather do it in the most noise-free place I could find...

Thread 'How feasible is home radio astronomy?'

Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...

Thread 'Visible light Over Large Distances'

How does light maintain enough energy in the visible part of the spectrum for the naked eye to see in the night sky. Also, how did it start of in the visible frequency part of the spectrum. Was it, for example, photons being ejected at that frequency after high energy particle interaction. Or does the light become visible (spectrum) after hitting our atmosphere or space dust or something? EDIT: Actually I just thought. Maybe the EM starts off as very high energy (outside the visible...
