Researchers dissecting a shooting star have found the oldest material that has existed on Earth. They discovered residue grains inside the space rock – which tumbled to Earth during the 1960s – that are as much as 7.5 billion years of age. The residue grains that are the oldest were framed in stars that thundered to long lasting before our Solar System was conceived. A group of specialists has depicted the outcome in the diary Proceedings of the National Academy of Sciences. At the point when stars die, particles shaped inside them are flung out into space.

These pre-solar grains at that point get fused into new stars, planets, moons and shooting stars. Philipp Heck, senior author of the research explained that they’re strong examples of stars, actual stardust. A group of analysts from the US and Switzerland examined 40 pre-sun powered grains contained in a segment of the Murchison shooting star, that fell in Australia in 1969. To determine how old the grains were, the specialists estimated to what extent they had been presented to grandiose beams in space. These rays are high-vitality particles that movement through our system and infiltrate strong issue.
