UNITED NEWS INTERNATIONAL (UNI) — A small rock found in Egypt might be older than the sun.
Scientists at the University of Johannesburg recently carried out an in-depth analysis of the so-called Hypatia stone.
The stone was found in 1996 surrounded by yellow glass in a remote part of the Sahara desert. It’s been studied for over two decades, yet scientists are still fascinated by it.
This new study published in the journal Geochimica et Cosmochimica Acta found the rock has only trace amounts of the mineral silica and large amounts of carbon.
This is strange because meteorites are usually made of the reverse: large amounts of silica and small amounts of carbon.
Scientists theorize that the solar system started as a cloud of dust and gas and eventually clumped together into planets with leftover pieces forming comets.
But the Hypatia stone doesn’t fit that mold.
Study authors say the rock challenges our understanding of how stars and planets form.
