After 4 billion years, the dwarf planet Ceres is still carrying a surprising amount of water weight — as much as 30 percent.
The finding, which was published in the Jan. 6 edition of the journal Science, is consistent with earlier models, and provides valuable clues to how Ceres formed.

Dwarf Planet Ceres Up To 30 Percent Water
Scientists studying dwarf planet Ceres have found that a 13,000-foot volcano there arose not from silicic magma, but from muddy, salty ice that rose to the ~160 K surface and quick-froze like Smucker’s® Magic Shell.
Finding such a dramatic cryovolcanic process this close to the sun – in the inner asteroid belt between Mars and Jupiter – is unusual, and bolsters the idea that Ceres might have originated in the outer solar system. It also lends credence to the notion that asteroids and comets might be more closely related than once thought.
