Giant blobs in Earth’s mantle may be driving a ‘diamond factory’

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

‘Star factory’ at Milky Way’s heart seen for the first time

Astronomers have reconstructed the history of star formation at the center of the Milky Way for the first time, finding that starbirth radiated outwards from the galaxy’s heart. The results also revealed that most young stars in the densely packed galactic center formed with only loose associations and drifted further apart over the course of … Read more
