Where Are All The Aliens? | Tim O'Brien | TEDxOldham

We now know of thousands of planets orbiting other stars. But we know of only planet that hosts life – the Earth. Most scientists think that life elsewhere in the Universe is likely to exist, but so far there is no evidence that extra-terrestrials exist or that they have visited us. However, we can search for signs of life on distant planets and we are even using radio telescopes to look for messages sent to us by extra-terrestrial civilisations. In this talk Tim will discuss the latest science behind the search for alien life. Tim is a Professor of Astrophysics and an Associate Director of Jodrell Bank Centre for Astrophysics at The University of Manchester. Tim’s research concentrates on the study of exploding stars using telescopes around the world and in space, working across the spectrum from radio waves to X-rays. Tim is passionate about astrophysics and its power to inspire. Well known for his regular contributions to science on TV and radio, he is Jodrell Bank’s host for the hugely popular BBC TV Stargazing Live series and has a monthly space discussion programme on BBC Radio 5 Live. In 2014, jointly with Professor Teresa Anderson, he was awarded the Kelvin Medal of the Institute of Physics for innovative public engagement, and in 2016 he was elected as President of the UK’s Society for Popular Astronomy. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx
