The phrase “silence is golden” is even more important for radio astronomers. The sheer amount of radio output created by humans can drown out any interesting signal from the heavens that they might wish to study. Those signals are also partially blocked by Earth’s atmosphere, adding more complexity to the challenge.
The obvious solution to the atmosphere problem is to launch space based observatories, and that has been done in the past. However, in near Earth orbit the radio waves emitted from radio stations all around the world can still blast any radio receiver with an unwanted deluge of signals. So scientists have come up with a novel idea to get the silence they so crave: park a probe on the far side of the moon.Continue reading “New Radio Telescope Is Going to Fly to the Far Side of the Moon to Listen to the Signals From the Early Universe”
