LONDON: When the earliest rocks were formed in the solar system they were porous, more like fairy floss than planet building material.UK scientists made the discovery after highly detailed analysis of a meteorite fragment from the asteroid belt between Jupiter and Mars.They now believe that the sun and its family of planets formed from a cloud, or "nebula", of dust and gas in which clumps gradually appeared due to the force of gravity.
