Scientists analysing a meteorite have discovered the oldest material known to exist on Earth.## More to be found Dr Heck told BBC News: "Only 10% of the grains are older than 5.5 billion years, 60% of the grains are "young" (at) 4.6 to 4.9 billion years old, and the rest are in between the oldest and youngest ones. "I am sure there are older pre-solar minerals in Murchison and other meteorites, we just haven't found them yet." Previously, the oldest pre-solar grain dated with neon isotopes was around 5.5 billion years old. The findings shed light on a debate over whether or not new stars form at a steady rate, or whether there are highs and lows in the number of new stars over time. "Thanks to these grains, we now have direct evidence for a period of enhanced star formation in our galaxy seven billion years ago with samples from meteorites. This is one of the key findings of our study," said Dr Heck. The researchers also learne
