When were Neptune’s rings first confirmed?

Neptune’s rings were confirmed in the early 1980s, with strong evidence emerging in 1984 from ground-based occultation observations. Astronomers saw a star’s light fade in a pattern that suggested incomplete or clumpy rings around the planet. The Voyager 2 flyby in 1989 then revealed that Neptune’s ring system exists, though it is faint and incomplete. Neptune’s rings are much less prominent than Saturn’s, but they are a real and scientifically important feature.
