The surface of our planet is littered with devices for radio astronomy. We have giant antennae dishes and antennae clusters in the US, China, Australia, Puerto Rico, South Africa, and Chile among many other countries of the world that possess radio telescopes. However, all these stations are not satisfactory for radio astronomers who are now thinking to install radio dishes on the far side of the Moon.
The signals captured by Earth’s radio telescopes could get altered by our radio waves
Radio telescopes are getting signals that travel through the Univers at the speed of light, therefore, some of the signals received by radio astronomers have traveled for millions of years before ‘hitting’ Earth.
And, even if these prehistoric signals are received by radio telescopes, they are altered by the Earth’s radio waves, such as GSM radio waves. Thus, the scientists are not getting a crystal-clear signal and the readings could be altered.
Radio telescopes on the Moon will help astronomers read crystal-clear signals
Just recently, the radio astronomers have come up with the idea of putting large radio dishes on the far side of the Moon.
“The far side of the Moon is the best place in the entire inner solar system for radio astronomy. All of this is futuristic, it’s going to take time but in principle, there should be no reason why we can’t do this,” admitted Joseph Silk, an astronomer at John Hopkins University.
“This is the one quiet place in our solar system, which we preserved. We’re now thinking about fantastic new space opportunities that could very well pollute it before we get a chance to exploit it for radio astronomy,” said Jill Tarter, a SETI researcher and an astronomer.
Even though there are no concrete plans to build and place radio telescopes on the Moon, the scientists consider that planning for the opportunity when something like this could happen is important for them to not lose momentum.
