Fifty New Exoplanets Discovered by HARPS
Astronomers using ESO's leading exoplanet hunter HARPS have today announced more than fifty newly discovered planets around other stars. Among these are many rocky planets not much heavier than the Earth. One of them in particular seems to orbit in the habitable zone around its star. In this video news release we look at how astronomers discover these distant worlds and what the future may hold for finding rocky worlds like the Earth that may support life.

Dr. Tara Shears - The LHC: the world's largest experiment.
The LHC: or how the world's largest experiment can investigate matter's smallest constituents. Public lecture on 21 June 2007 at The Royal Society, London. Go here if you want to see the lecture with slides: http://royalsociety.tv/rsPlayer.aspx?presentationid=183 By Dr. Tara Shears, Royal Society University Research Fellow, University of Liverpool. Deep beneath the Swiss countryside, final touches are being made to the world's largest piece of scientific equipment the Large Hadron Collider (or LHC for short). The LHC is the most powerful particle accelerator ever built. It is capable of recreating the very energetic conditions last seen in the universe a billionth of a second after the Big Bang, and allows particle physicists to study the fundamental ingredients of matter that the universe was formed of at the time. Amazingly, it will do this 40 million times a second, and use enormous high tech experiments to record what happens. Why would we want to go to such lengths to explore the structure of matter? In this lecture, Tara Shears will discuss how the LHC will help scientists learn more about the nature of matter and expand the frontiers of our knowledge further than ever. Tara Shears is a particle physicist and Royal Society University Research Fellow at the University of Liverpool. Since obtaining her PhD in 1995 she has worked on experiments at CERN, the European Centre for Particle Physics, in Switzerland, and at Fermilab in America. Her research interests focus on the properties of bottom quarks and the light they may throw on new fundamental particles and interactions.
