Recent research featured in Earth and Planetary Science Letters uncovers interesting findings about this ancient ring and its anticipated ... ultimately causing the Hirnantian Ice Age, which ...

For the first time, astronomers have imaged dozens of belts around nearby stars where comets and tiny pebbles within them are ...

A new study implies that in the past, moons in our solar system may have had rings just like planets do — deepening the mystery of why no ringed moons exist today.

What the astrophysicists are therefore observing is where the ice reservoirs of planetary systems are located ... Some are narrow rings, as in the canonical picture of a 'belt' like our solar ...

Exocometary belts – regions containing many such icy bodies – are found in at least 20% of planetary systems ... exocomets are frozen as ice. While most exocometary belts in the latest study are disks ...
