Just one of a very few possible finds from the Observatory's gutters |
To that purpose I mobilised the Jodrell Plank Observatory team to get up on the roof and go prospecting!
Many micrometeorites contain magnetite, a magnetic form of iron oxide and commonly known as lodestone. So once the team had collected a pot of dust from the Observatory gutters, the magnetic particles were separated from the rest using a neodymium magnet. The magnetic particles were then inspected under a microscope. Post industrialisation, much of the magnetic dust in our atmosphere is man-made rather than extra-terrestrial. So whether we found any micrometeorites is debatable. What cannot be denied however, is at no appreciable cost, the Observatory's roof gutters have never been so clean".
