Planet Uranus Rings

ALMA recently imaged the rings around planet Uranus

One interesting observation:
'
"The rings of Uranus are compositionally different from Saturn's main ring, in the sense that in optical and infrared, the albedo is much lower: they are really dark, like charcoal,"
'

I should have added this excerpt:

'
Rings could be debris remaining from the time of formation 4.5 billion years ago.
'

I find it incredible these ring are unchanged in that span.
