When you consider that Neptune’s rings were spotted in the 1980’s this really does remind you of how little we have actually found.  There could be rings in places we have no idea about.  Here is more on what they said:

By comparing what was seen from different sites the team could reconstruct not only the shape and size of the object itself but also the shape, width, orientation and other properties of the newly discovered rings.

The team found that the ring system consists of two sharply confined rings only seven and three kilometres wide, separated by a clear gap of nine kilometres — around a small 250-kilometre diameter object orbiting beyond Saturn.

Where do you think they will find rings next?  Perhaps an exoplanet or even around kepler 452-b?

We have a feeling there will be more discoveries like this pretty soon.
