The answer to this question is a debate among scientists, but a new study published in the journal Astrophysics has developed a mechanism to solve the problem.
According to researchers at the Massachusetts Institute of Technology (MIT), if a 1 to 2 megawatt laser is focused on a telescope measuring 30 to 45 meters and directed to the space, it will produce a more powerful infrared beam. 39, energy from the sun, and attracts attention from a distance of 20 000 light-years.
She explained that this signal could be detected by space creatures, if they exist and live in nearby planetary systems, such as Procisma Centaurus, a planet out of the mass of the solar system, such as the mass of the Earth revolves around a nearby star at 432 light-years away.
The required laser energy of 1 to 2 megawatts equates to the airborne laser power of the US Air Force, a megawatt laser now inactive for the purpose of launching ballistic missiles from the sky.
The launch of the laser requires the construction of large telescopes, such as the giant 24-meter Magellan telescope and the very large 39-meter European telescope, both under construction in Chile.
