'Unidentified Flying Objects'

Unidentified Flying Objects: Are there any images of UFOs that need an extraterrestrial explanation?

Dr Steve Barrett is a Senior Research Fellow in the Department of Physics at the University of Liverpool. His research interests have centred around the applications of imaging and spectroscopy to fields such as nanoscience, geomaterials, biomedical imaging and infrared spectroscopy. He is an expert in image processing and image analysis and has written image analysis software that has been used by researchers throughout the world. His interest in astronomy predates his professional career as a physicist. He has given hundreds of astronomy-related talks to astronomical societies, special interest groups and schools to an audience totalling over 20,000 people. As a result of giving these outreach talks he was awarded the Sir Patrick Moore Prize in 2019 by the British Astronomical Association. **COVID Security** Although the rules have changed somewhat - we're still being cautious about the threat of COVID-19. Here are some things you could do to help look after yourself and our other attendees: • If you have access to a lateral flow test, why not take a test before you join us? If it's positive for COVID-19, please stay at home. • If you have new symptoms of COVID-19, even if a lateral flow test is negative - we'd prefer you stay at home. We'll have other social events in the future that you can join in when you're feeling better. • If you feel comfortable and able to wear a mask while moving around the venue then please do wear one. We'll bring some spares if you'd like to wear one but forgot to bring one. • We'll also bring some hand sanitiser that you're free to use any time. • Please be respectful of other people's boundaries. Give each other plenty of space and be considerate. If you need to cough or sneeze, cough into your elbow or a tissue and throw the tissue away before sanitising your hands.
