The boundary zone between Earth’s molten metal core and the mantle, its rocky middle layer, might be a diamond factory. A new laboratory experiment finds that, under extreme temperatures and pressures, the combination of iron, carbon and water — all potential ingredients found at the core-mantle boundary — can form diamond. If this process also … Read more

The Denisovans, together with the Neanderthals, are the closest extinct relatives of modern humans. It wasn’t until 2010 that scientists announced that the they existed, so much about them remains unknown. However, fossil and genetic evidence suggests the Denisovans lived across a wide range of areas and conditions, from the cold mountains of Siberia and … Read more
In Liu Cixin’s short story “The Wandering Earth (opens in new tab)” (first published in Chinese magazine Science Fiction World in July 2000), Cixin portrays a scenario in which the planet’s leaders agree to propel Earth out of the solar system to escape an imminent solar flare that is expected to decimate all of the … Read more
Every year, millions of rocky shards from outer space burn up in Earth’s atmosphere, many briefly flaring and appearing in the sky as “shooting stars.” But how many survive their high-speed plunges to strike the ground? Rocks from space that land on Earth are known as meteorites. Giant impacts, such as the one that likely … Read more
Somewhere out there, there’s probably a person who has your face. And this unrelated look-alike may have more in common with you than appearances, a new study suggests. The surprising research, based on 32 pairs of unrelated doppelgängers from around the world, shows that two people who have a strong facial similarity to each other … Read more
All life on Earth owes its existence to the sun’s radiant heat. But what happens when that radiation surges out of control, and billions of tons of charged solar material suddenly barrel our way at thousands of miles a second? What happens when Earth takes a direct hit from a solar flare — and could … Read more
The Artemis mega moon rocket is NASA’s latest and most powerful launch vehicle, intended to return astronauts, robots, and supplies to the moon for the first time in more than 50 years. It consists of a multistage rocket called the Space Launch System (SLS), which can carry various additional modules atop it, such as the … Read more
