duration/ Data collected by NASA’s Kepler space telescope, along with other observatories around planets outside our solar system, revealed that Earth is one of about 40 billion potentially life-sustaining planets in our Milky Way, with about one planet forming capable of supporting life. every year.
According to the Jeddah Astronomical Society, this information is of interest to all the inhabitants of the Earth, but taking into account that our Milky Way galaxy is more than 100,000 light-years in diameter and that light travels about 186,000 miles per second.
So it would take 4 years for the radio signal to reach the nearest star system called Alpha Centauri and 100,000 years to travel from one side of the galaxy to the other.

Intelligent civilizations are expected to be separated by at least 1,000 light-years in the Milky Way, which is a large distance.
According to astronomer Majed Abu Zahira, the available example is the Earth because everyone knows that life will appear and continue as long as the conditions are appropriate for that, but sane life flourished at a later time.
And the signals sent by humans several decades ago into space could be the only ones in our Milky Way.
But this does not mean stopping the search. With the development of wireless communications, radio astronomy, and data collection techniques, they must all be adapted to search for sane life in outer space, and this has already been done within the “City” program more than 60 years ago until today.
