Of course not. But there is a fundamental difference between civilian scientific instruments and tactical surveillance networks.Do you think only the military operates instruments that gather data?
Astronomy is not limited to deep space there's a lot of wide angle astronomy;Of course not. But there is a fundamental difference between civilian scientific instruments and tactical surveillance networks.
Academic institutions point telescopes at specific deep-space targets for astrophysics or track known orbital satellites; they do not operate all-sky, low-altitude air defense radar networks or classified early-warning satellite constellations. Airspace monitoring is a matter of national sovereignty, strictly managed by military and aviation authorities who do not share raw, classified telemetry with civilian universities.
As far as I know, this is something civilian science simply hasn't done in 80 years of history.
I see your point.Astronomy is not limited to deep space there's a lot of wide angle astronomy;
Vera C. Rubin, ZTF for transients (at Palomar ala the recent controversial transients linked to nuclear tests study), Pan-STARRS, ATLAS etc
Then there's web camera networks, volcano/wildlife etc monitoring cameras, weather RADAR and ocean/climate stations that are non military.
Not to mention billions of people now with camera phones, of course they are less capable than military systems however it seems likely there would be SOME data that would stick out somewhere, especially given the application of current consumer/commerical technology to the same type of encounters reported and recorded many decades ago when there was much less and lower quality recording technology around.
