Let's Get Astrophysical on Oxford Road: October

Over the last 200 years, 21 meteorite falls have been witnessed in the British Isles (UK and Ireland). There are also several known British meteorite “finds”, i.e. meteorites that were found, but not observed to fall. Many of the British meteorites are of significant historical as well as scientific interest. Two falls around 1800, Wold Cottage (Yorkshire, 1795) and High Possil (Glasgow, 1804), were among the first meteorites whose scientific value was recognized. Most British meteorites are a common class called ordinary chondrites, which come from asteroids and include some of the first solids to form within the Solar System. Two of the meteorites are rarer classes, an iron and a primitive achondrite. These are derived from asteroids that underwent melting and core formation shortly after they accreted, 4.6 billion years ago. In this presentation, I will discuss the history and science of British meteorite falls. I will also provide an overview of the scientific importance of other meteorite classes, including lunar and martian meteorites. If we are very lucky one of these could be our next fall, any day now!
