Space junk? - Sure, any anomaly is worth looking at - But notice, we have fairly high powered telescopes,
techno advanced satellites, etc. for many years - And if 'they' {NASA, etc.} have found anything

And that brings the skeptical - 'IF" a government agency found genuine proof of an existent alien
civilization - Would they tell the world about it?
