A dark reddish-brown stone, picked up from the Sahara desert in Morocco a few years ago, appears to be an Earth rock that was flung into space where it stayed for thousands of years before returning home – surprisingly intact.
Early diagnostic tests show the unusual stone features the same chemical composition as volcanic rocks on Earth. Interestingly, however, a few of its elements seem to have been altered into lighter forms of themselves. These lighter versions are known to occur only upon interacting with energeticin space, which provided one of two key pieces of evidence declaring the rock's trip beyond Earth, geologists say.
submarine volcano last year peaked at 36 miles — well before the edge of Earth's atmosphere, a threshold the meteorite seems to have flown far beyond. "I purchased this one just because it was odd," said Jambon."Nobody knows what this stone is really worth." "It is an interesting rock that would deserve more investigations to be conducted before making extraordinary claims," said Ludovic Ferrière, a curator of the rock collection at the Natural History Museum Vienna in Austria, who was not involved with the new study.
