Saturn: boulders. Earth: space junk
I suppose if StarLink and such prevent you from looking at the stars you have to go and look at the data.
The infall of icy debris from Saturn's rings is heating the planet's upper atmosphere, according to astronomers, who discovered the phenomenon among old data that was once considered noise. Saturn is distinctive in our Solar System with its large, complex ring system, composed of chunks of ice and rock that have been captured …
Einstein apparently said to a university student who observed that the exam questions matched those of the previous year.
Science is a continuous journey of discovery and we all would do well not to be too dogmatic about what we 'know' now.
'Current understanding' would better describe scientific knowledge.

Technically yes, but if those rings are faint enough to prevent actually seeing them, would the radiation of falling debris be noticeable at a distance?... After all, we did actually see Saturn's rings way before we noticed the radiation anomaly.
" If a spacecraft detects similar excess UV radiation bands in the upper atmosphere of a faraway planet, it could mean it might be supporting a ring system like Saturn's."
I am not very well informed about this topic, but it only took a few seconds to verify that Jupiter, Uranus and Neptune all have ring systems - wouldn't one of them make a nice instance to look for the tell-tale increased levels of Lyman-alpha radiation? I expect none of these would produce the same levels as Saturn, but then extra-solar examples would produce much smaller signals, surley?
