Candy floss of rocks

"The earliest rocks in the solar system, from which the terrestrial planets were born, were more like candy floss than hard rock, according to a new analysis carried out by a team including researchers in the UK and Australia. This is the first geological evidence to support the idea that the first solid material in the solar system was extremely porous before it was subsequently compacted into larger bodies, which become the planets we know today."
