Radio signals can indeed propagate through a vacuum, allowing for the transmission of data and messages across space. This technology is utilized by satellites and spacecraft to send images and information back to Earth. The discussion highlights the potential for using radio frequencies in the search for extraterrestrial intelligence. Resources like the SETI project provide further insights into these methods. Effective communication across vast distances in the universe is feasible through established radio signal technology.

Of course radio signals propagate in a vacuum. How do you think all those nifty pictures get here from our satellites and spacecraft ?

Thread 'Looking for info about the Sombrero Galaxy'

Hi, I saw someone with an avatar on a different forum that turns out to be the sombrero galaxy. AI says, too distant to know much about, aside from billions of starts, potentially tons of planets, and a supermassive black hole in the center. I find that setup fascinating, despite knowing close to nothing about the universe. So I ask: could anyone point me in the direction of, or provide information about this galaxy? I do not trust AI beyond general information, and I like to go pretty...
