Meteorites, dust and other space rubbish is falling to Earth all the time, but does any of it ever contain life? We find out if aliens hitch a lift on space rubble in this Question of the Week. Plus, we ask how does wood become petrified? Can it happen quickly enough for us to find petrified fence posts? Like this podcast? Please help us by supporting the Naked Scientists
