Gold isn’t rare on Earth — it’s buried 3,000 kilometres too deep to reach. In 2025, scientists found that more than 99.999% of the planet’s precious metals are locked in the core, while Hawaiian lava carries traces suggesting some of that core material is slowly l

Geochemists at the University of Göttingen have found chemical evidence that material from Earth's core is mixing into the mantle plume that feeds Hawaii's.

For 21 years, Voyager 1’s primary roll thrusters were considered dead. Then in 2025, NASA tried to wake them up from 15 billion miles away — knowing that if they fired cold, they could explode, but if they stayed dead, the spacecraft might one day lose its aim

For most spacecraft, a failed thruster is an engineering problem. For Voyager 1, it is a problem stretched across interstellar space, handled by commands...
