Building light lighthouse in space to attract aliens

Researchers from the Massachusetts Institute of Technology (MIT) have proposed an idea to attract the attention of the scientific community when the idea of ​​building a "light lighthouse" to attract attention in .

In our mission to find extraterrestrial life, we are not alone in the vast universe, projects to search for alien life are still being studied by scientists around the world. The idea of ​​researchers from Massachusetts Institute of Technology (MIT) is not outside of that mission.

This idea is impressive because it offers a new way to help aliens know us, instead of finding them, up to 20,000 light-years away.

The idea of ​​deploying a 'light lighthouse' attracted the attention of an author group from MIT that is attracting the attention of the scientific community.

In an article published in the Astrophysical Journal, the MIT team describes how to use a laser beam of between 1 and 2 Megawatts in combination with a 30 to 45 meter telescope to create a special lighthouse. With this design, infrared radiation from the given system will be strong enough for a 'smart species' in the universe to distinguish it from the light of the sun.

"When they discovered us, we could emit a message, with a data rate of several hundred bits per second. This is a challenging project but it doesn't mean impossible. Technology Our present can do this , 'said James Clark, the project's author, graduate student at MIT's Aerospace Department.

However, the idea of ​​this project is also encountering some criticism because although it cannot be seen with the naked eye, there may be some risks to spacecraft or affect the market. human force when looking at the beam of light emitted.

Before criticizing comments, James Clark said, to solve this problem we can build on the moon instead of on Earth.

Currently, the idea of ​​this project is still being discussed. The authors from MIT hope it will be deployed in the future.
