The complex chemical structures found in a meteorite from Mars, which scientists in 1996 hailed as possible evidence of past life on the planet, can be reproduced quite simply in any laboratory according to new research from the University of Greenwich. Professor Aron Vecht and researcher Terry Ireland from the university’s School of Chemical & Life Sciences say that the special structures — which are shaped like flowers and spheres — could have been formed on the cold surface of Mars from minerals commonly occurring there. Their findings cast grave doubts on the possibility of Martian life.
