Feb 24, 2012 · Extent of human radio broadcasts Humans have been broadcasting radio waves into deep space for about a hundred years now, since the days of Marconi. That, of course, means there is an ever-expanding bubble announcing Humanity's presence to anyone listening in the Milky Way. This bubble is astronomically large (literally), and currently spans …

Oct 18, 2021 · October 18, 2021. What’s Causing the Mysterious Radio Waves Coming From the Center of the Milky Way? By Evan Gough. The center of the Milky Way is a mysterious place. Astronomers think there’s a supermassive black hole there, though it could be dark matter instead. The region is densely packed with stars, dominated by red giants.

The space station looks like an airplane or a very bright star moving across the sky, except it doesn't have flashing lights or change direction. It will also be moving considerably faster than a typical airplane (airplanes generally fly at about 600 miles per hour; the space station flies at 17,500 miles per hour).

NASA - Astronomers Find Largest, Most Distant Reservoir …
Jul 22, 2011 · Image credit: NASA/ESA. Two teams of astronomers have discovered the largest and farthest reservoir of water ever detected in the universe. The water, equivalent to 140 trillion times all the water in the world's ocean, surrounds a huge, feeding black hole, called a quasar, more than 12 billion light-years away.

How are radio waves detected?
Radio waves can be detected using a coherer. This is a small plastic tube filled with iron fillings. When the Van de Graaff discharges with a spark radio waves jiggle up the iron fillings making the electric circuit complete and thus lighting the LED.

What is the wavelength of radio?
The distance a radio wave travels in one second, in a vacuum, is 299,792,458 meters (983,571,056 ft) which is the wavelength of a 1 hertz radio signal. A 1 megahertz radio signal has a wavelength of 299.8 meters (984 ft).
