Comets may have transported water to a young planetary system
Astronomers at Lund University in Sweden have found evidence of exocomets – comets in other solar systems – orbiting a young star similar to our Sun. The observations point to a possible mechanism for how water might be transported from the cold outer regions of the planetary system to regions where planets form.
