The asteroid is called Psyche and until now it was thought to be dry. But new evidence suggests there’s water there, bound up in rock.

That’s according to Driss Takir, a scientist at the U.S. Geological Survey. His team observed the asteroid from a telescope in Hawaii and saw a spectral signature consistent with water.

Psyche is made of nickel and iron and could be the core of a destroyed planet. It’s located in the asteroid belt between Mars and Jupiter. The research team thinks it may have picked up water from violent collisions with other asteroids.

A separate team of scientists at Arizona State University has proposed a spacecraft mission to Psyche for further exploration. If NASA funds the project, it would be the first mission to a metal asteroid.
