Now, scientists believe that those oceans were possibly made of water.

But a new study throws a wrench in that idea by suggesting those oceans could actually be made of magma.

Thanks so much for joining us.

Thanks, John. So tell me more about these

Hyseian planets and why scientists are suddenly thinking magma now in the
