7 Billion Year Old Stardust Is Oldest Material Discovered on Earth

Scientists have discovered the oldest firm material on Earth – stardust supposed to have created about 7 billion years ago. The meteorite pieces came down in September 1969 in the town of Murchison, in Australia’s Victoria state. Stardust is a matter that develops as small particles in space when stars depart. These scraps can be used later to create new planetary bodies, including stars, planets, and moons. Scientists said the stardust particles “became trapped in meteorites, where they remained unchanged for billions of years.” This makes the samples “time capsules” of events that occurred before the solar system.
