Scientists have spotted water in a primitive meteorite, expanding our understanding of the ancient solar system. 

Water is abundant in our solar system — from the icy rings of Saturn to the subsurface water on its moon Enceladus and the liquid water and ice detected on Mars, water is known to exist beyond Earth. However, while scientists have suspected that water is preserved in a type of meteorite known as carbonaceous chondrites, they have never discovered liquid water in these rocks  — until now.
