The Earth has a long and violent history of collisions with extraterrestrial bodies such as asteroids and comets. Massively more destructive than a global nuclear war, this is the hazard that is most likely to precipitate the end of civilisation as we know it, but It is also the only major natural hazard that can be predicted and prevented. Here, Jay will discuss the nature and extent of the Near Earth Object (NEO) hazard and how it can be dealt with. Building 207 on University Plan at http://www.liv.ac.uk/files/docs/maps/liverpool-university-campus-map.pdf Talk starts at 6.30 p.m. with tea and coffee available from 6pm.Continue Reading »
The history of computer simulations of galaxies like our own Milky Way is dotted with remarkable successes, but an even greater number of impressive failures. This inability to make a model of the Milky Way is quite surprising, given that the basic physics is well understood, and part of the A-level syllabus here in the United Kingdom. Recent advances suggest that we might have finally made a breakthrough, making use of powerful supercomputers and novel approaches to feeding energy into the forming galaxies. Brad will demonstrate how we “mine the fossil record” of our simulated galaxies, comparing and contrasting the […]Continue Reading »
For International SUN-day, June 22nd 2014, The Liverpool Astronomical Society is hosting a FREE solar observing day at their Leighton Observatory, Pex Hill, Cronton. The event runs from 1pm to 5pm, and will give people the opportunity to SAFELY view the sun through specially adapted telescopes, allowing you to see details you would never normally be able to view. There are also illustrated talks taking place, along with free tea, coffee and biscuits. Please remember, if you do NOT have specialist equipment you must NEVER view the sun through a magnifying device such as binoculars or telescopes – without the […]Continue Reading »
