​There are few places on Earth as isolated as Trindade island, a volcanic outcrop a three- to four-day boat trip off the coast of Brazil.

A large submarine volcano is likely erupting below the surface of the Pacific Ocean, according to scientists with the U.S. Geological Survey, citing discoloration.

A beautiful blue flaw in a gem-quality diamond from Botswana is actually a tiny fragment of Earth’s deep interior—and it suggests our planet’s mantle contains oceans’ worth of water. The flaw, technically called an inclusion, looks like a fish eye: a deep blue center surrounded by a white haze. But it’s really a pocket of the mineral ringwoodite from 660 kilometers down, at the boundary between the upper and lower mantle.

Boom! And just like that, a new island was born.

Lead researcher Dr. Milo Barham, from the Timescales of Mineral Systems Group within Curtin's School of Earth and Planetary Sciences, said the team devised a metric, which determines the "age distribution fingerprint" of minerals known as zircon within sand, shedding new light on the evolution of the Earth's surface over the last few billion years.

It took scientists 375 years to discover the eighth continent of the world, which has been hiding in plain sight all along. But mysteries still remain.
