Search for exoplanets and biosignatures
A new stage is studying the atmospheres of exoplanets for gases associated with life (oxygen, methane). This is an indirect, but promising path.

Active search – sending messages
Projects that send radio signals into space (for example, messages to Arecibo) are trying to establish contact deliberately, rather than waiting for a response.
Philosophical and ethical questions
Do we need to search and send signals at all?
How will we react to contact?
How to avoid the possible risks of encountering a civilization that may be technologically superior?
These questions are increasingly being discussed in the scientific community.
Conclusion: Are we searching correctly?
The search for extraterrestrial intelligence is a huge challenge that requires patience, technology, and imagination. Today, we have powerful tools, but even their capabilities are limited by the cosmic scale and our understanding of communication.
Perhaps a real breakthrough will come with the advent of new technologies, such as quantum sensors, powerful radio telescope arrays (such as the Square Kilometre Array), or with a change in the search paradigm itself.
In any case, the search continues – and each new observation, each unrecognized anomaly brings us closer to one of humanity’s greatest discoveries.
