Found the oldest solid material on Earth, 'older' than the Sun.

Scientists have found some star dust that is about 5-7 billion years old inside pieces of meteorite, found south of the town of Murchison, Victoria, Australia. These meteorites fell from the collision of a giant meteorite with the Earth's atmosphere in 1969.

Tiny star dust has been discovered to be the oldest solid material ever found on Earth, even older than the Sun. According to scientists' research, our Sun is about 4.6 billion years old.

Heck and his colleagues took 40 samples of stellar dust from the Murchison meteorite and studied them. The results show that the majority of stellar dust is much younger than the Sun, but a few of them are more than 5 billion years old.

Heck said these star dust could have occurred from the bursts of a number of stars that existed before the solar system formed.

Researchers at the Field Natural History Museum in Chicago, Philipp Heck, say these stars are important, helping scientists understand how stars form in the Milky Way as well as the stars. the creation of the universe as well as the Solar System.
