As they pass through the rings around planets, these radio signals are affected in different ways by the particles in the ring, depending on the size of the particles and how heavy they are. Saturns rings are predominantly made of water ice, but also contain small amounts of rock and dust. Rings around gas giants are thought to be transient over the the lifetime of the planetary system. Its possible that with this new telescope, we will even find rings around moons, not just planets. Pluto is not known to have any ring systems, but some astronomers think that the New Horizons probe might find a ring system when it visits in 2015. A ring system is a disc or ring orbiting an astronomical object that is composed of solid material such as dust and moonlets, and is a common component of satellite systems around giant planets.

It is believed that the colour radiating from the halos depends on how it is deflected by the crystals. A ring is a collection of vast numbers of particles, each like a tiny moon obeying Kepler's laws as it follows its own orbit around the planet. A Planetary Society Shoemaker Grant winner helped make the discovery. The rings are generally dark and dusty, similar to the Uranian rings. It also has different colours.
