Scientists have found the oldest solid material from a meteorite that crashed into rural southeastern Australia in a fireball in 1969. The meteorite predated the formation of our solar system by billions of years. The oldest of 40 tiny dust grains trapped inside the meteorite fragments retrieved around the town of Murchison in Victoria state dated from about 7 billion years ago, about 2.5 billion years before the sun, Earth.
