Could the molecular cloud be nearer to our solar system than estimated. If they are right we have a new kind of planet building material – the focus of the news release. These are mid-size interstellar particles, midway between dust and large objects.

At … NASAs GRAIL mission, to the Moon, has mapped it inner structures by measuring the pull of gravity on the satellites from points on the ground below. The greater the shift the denser the structure of the Moon.
