̽��ֱ��past year has been an extraordinary one for particle physicists and cosmologists, with the Planck satellite revealing the Universe’s earliest light, and the tentative discovery of the Higgs-Boson at the Large Hadron Collider (LHC).

Data collected from LHC experiments and the Planck mission - and their implications for the Universe - will be discussed by some of the giants of cosmology and particle physics during this week’s COSMO conference, all of which is being streamed live on YouTube.

Alongside the five-day long scientific conference - with days variously focused on Particle Physics, Cosmic Microwave Background, Large-Scale Structure, Primordial Cosmology and Cosmic Acceleration - there will also be a public symposium tonight, which, with speakers such as Stephen Hawking, Brian Cox and Andrew Liddle, will be a highlight of the COSMO YouTube broadcast.

Andrew Liddle, Professor of Theoretical Astrophysics at the ̽��ֱ�� of Edinburgh, will open the symposium with a talk on cosmology and the Planck satellite, currently being used to map the relic radiation expelled by the Big Bang. COSMOS 2013 is one of the first opportunities for researchers to gather and discuss the recent discoveries, with other lectures on the Planck data from George Efstathiou (Institute of Astronomy) and Ben Wandelt among others.

̽��ֱ��Planck satellite has given us a highly detailed image of the Universe a mere 380,000 years after the Big Bang; and will be used by researchers to learn about the origins of the Universe, its probable fate, and, ultimately, about existence itself.

̽��ֱ��night’s second speaker, Professor Brian Cox, has been credited with helping to demystify physics for the public. ̽��ֱ��former musician is now a particle physicist, Royal Society research fellow and professor at the ̽��ֱ�� of Manchester; he also works on the ATLAS experiment at the CERN super collider. Though a full time lecturer at Manchester, he is a prolific broadcaster and host of many science programmes such as the recent BBC series Wonders of Life.

̽��ֱ��symposium will finish with a talk from Stephen Hawking, the world-famous theoretical physicist, cosmologist and author. Hawking, author of the best-selling A Brief History of Time, gained his Ph.D. at Trinity Hall, Cambridge, was the Lucasian Professor of Mathematics at the ̽��ֱ�� for 30 years and is a Fellow at Gonville and Caius College. He is also the Director of Research at ̽��ֱ��Stephen Hawking Centre for Theoretical Cosmology at the ̽��ֱ��.

Among Hawking’s many achievements is the proposal that black holes are not entirely black, but instead emit a type of thermal radiation now known as “Hawking radiation”. His talk, entitled Fire in the Equations, is likely to prove a spell-binding conclusion to the public evening of COSMO 2013.

COSMO 2013 is sponsored by Intel who are providing the live feed for the public event. Richard Curran, Intel Director Enterprise Server and Software Enabling Group EMEA, said “At Intel we have a long and successful history of working with Professor Hawking.�� We are proud to be supporting the team in its analysis of the data collected from the Planck satellite and wait with great anticipation to the insights the research can offer us about the universe and its origin. We are excited to open this research up to the public and we hope it encourages more people to take an interest in physics and the amazing work being done”.
