The researchers propose to create a “beacon” which will be visible at a distance 20 thousand light years.
A graduate of the Massachusetts Institute of technology James Clarke said that with the help of laser technology on Earth to create a “beacon”, which will be visible at a distance 20 thousand light years and will be able to attract the attention of extraterrestrial astronomers, if they exist.
To develop Clark proposed to use a laser power of 1-2 MW and a telescope diameter of primary mirror which is 30-45 meters. As a result, you will create a beam of infrared light that will be strong enough to stand out on the background of solar energy.
According to the scientist, this beam can be seen by alien astronomers who study in our region of the milky Way, especially if they are in nearby systems, such as the planets orbiting Proxima Centauri. Clark emphasizes that if this laser be seen by alien astronomers, they can use the same technology to communicate with the inhabitants of the Earth.
