It is composed of silicates and metallic nickel-iron, and may be the core remnant of a large asteroid that was destroyed by an ancient collision. Metis is the name of the goddess of elemental wisdom, mother of Athena.
Chasing the Higgs with The Large Hadron Collider: While temperatures inside the tiny beams of colliding particles can reach temperatures 100,000 times hotter than the Sun, the cooling system circulating around the accelerator ring is lowered to around -456 degrees Fahrenheit -- colder than outer space.

Asteroids found to be the moon's main 'water supply'
Asteroids found to be the moon's main 'water supply' -- Water reserves found on the moon are the result of asteroids acting as 'delivery vehicles' and not of falling comets as was previously thought. Using computer simulation, scientists have discovered that a large asteroid can deliver more water to the lunar surface than the cumulative fall of comets over a billion year period. | ScienceDaily
