Earth Detecting Earth
This study asks what another civilization with current-like technology could detect about Earth and finds that some human technosignatures are visible much farther than intuition suggests.

A practical inversion: what of us is detectable at interstellar distance?
It directly informs how humans should think about outbound messaging and unintentional leakage.
Key points
Radio leakage and radar are central in the study.
The work helps prioritize what detectable technology looks like.
It turns contact strategy into a two-way detectability problem.
Reference ledger

A dedicated SETI instrument with wide-field advantages
The ATA is one of the clearest examples of hardware built with SETI as a primary mission rather than as an occasional side use.
