Floods of the past, new worlds of the future

Thanks to recent advances in technology, there has been an explosion in the discovery of new planets orbiting stars other than our Sun. We will take a look at some of the most recent and bizarre of these worlds. Some of these planets orbit 3 stars, have seasons that last just hours, have no day or night and have moons bigger than Neptune. Many of these are far stranger than anything conceived by science fiction.

The City of Lincoln is situated at the confluence of the River Witham and the Fossdyke canal, an artificial waterway connecting the River Trent to the Witham via Brayford Pool. It is generally believed the Fossdyke was constructed during the Roman Period, but this is based solely on limited historical evidence. This presentation summarises new research on the Fossdyke based on radiocarbon dating of sediments infilling an old river channel near Burton Waters. If correct, the dates indicate this section of the Fossdyke was built during the early Iron Age, well before the Roman occupation.
