Mystery of the antimatter: science & cinema mix

Science & cinema join forces in Angels and Demons on general release, which tells the story of a plot to blow up the Vatican using “antimatter” stolen from Cern, the European Organisation for Nuclear Research. While it is currently impossible to build such a bomb, antimatter is a hot research topic.

Irish scientists are deeply involved in the production and analysis of antimatter at Cern, near Geneva. NUI Maynooth PhD graduate Dr Paul Bowe leads the group producing antimatter on Cern’s Alpha experiment. One of his team members is an Irish PhD student, Eoin Butler. Meanwhile, University College Dublin’s Dr Ronan McNulty, who leads the only experimental particle physics research group in the Republic, is involved in Cern’s LHCb antimatter experiment. It is one of the major experiments attached to the Large Hadron Collider (LHC), the 27km-long atom smasher that can also produce antimatter particles.

Antimatter is easy to understand but very difficult to handle, says Dr Bowe. Our universe apparently consists of nothing but “ordinary” matter, the stuff that we, the things around us, the planets and the stars, are made of. The atoms in matter have a positively charged nucleus surrounded by negatively charged electrons. Antimatter is the reverse of this. Its atoms have a negatively charged nucleus, called an “antiproton” and positively charged electrons called “positrons”. Read Dick Ahlstrom's full article here

Visions of Sun's great 'belches'

Nasa's Stereo orbiters have captured stunning new images of spaceborne debris thrown out from the Sun. The twin spacecraft have seen Coronal Mass Ejections (CMEs) hurling material into a comet, ripping off its tail. Scientists hope the probes will allow better forecasting of CMEs, which sometimes disrupt communication systems on Earth.

Explore Space with Google Sky


The constellations of Andromeda, Hydra and Vulpecula are now just a mouse click away for star-gazers, following the launch of Google Sky. The tool is an add-on to Google Earth and will allow astronomers a chance to glide through images of more than one million stars and 200 million galaxies. Optional layers allow users to explore images from the Hubble Space Telescope as well as animations of lunar cycles.

"The basic idea is to take Google Earth and turn it on its head," Ed Parsons, Geospatial technologist at Google told the BBC News website.
