• Previous SETI projects have utilized various methodologies to scan the cosmos for technosignatures.

Purpose of the Study:

• To provide an overview of current worldwide SETI initiatives.
• To explain the rationale behind the chosen methodologies in SETI research.
• To define the limitations of current SETI results.

Main Methods:

• Review of ongoing global SETI projects and their observational strategies.
• Analysis of signal detection and data processing techniques.
• Assessment of the sensitivity and scope of current SETI searches.

Main Results:

• Summary of the scope and scale of contemporary SETI endeavors.
• Identification of key methodological choices and their justifications.
• Presentation of the current constraints and limitations in SETI data analysis.

Conclusions:

• SETI efforts are active globally, employing diverse strategies.
• Methodological choices are critical for maximizing detection potential.
• Current results provide valuable insights but are limited by technological and observational constraints.
