This area deals with the fundamental laws and building blocks of nature and how they interact, the properties and the behavior of matter, and research into space and time and their structures.
innovations-report provides in-depth reports and articles on subjects such as astrophysics, laser technologies, nuclear, quantum, particle and solid-state physics, nanotechnologies, planetary research and findings (Mars, Venus) and developments related to the Hubble Telescope.
Spinning black holes could be responsible for at least some of the immensely powerful gamma-ray bursts (GRBs) astronomers observe coming from distant galaxies. On Tuesday 8 April, Sheila McBreen of University College, Dublin, will tell the UK/Ireland National Astronomy Meeting in Dublin that her analysis of the way gamma-rays were emitted over the course of outbursts from a large sample of GRBs has revealed particular signatures, most likely to be those of a rotating black hole either being “spun up”
An international team of astronomers has discovered that “dark matter”, the mysterious material that seems to make up most of the mass of galaxies, is not as all-pervasive as previously believed. Surprising new results from studies of several elliptical galaxies show they are not surrounded by halos of dark matter as was expected. The findings will be presented at the UK/Ireland National Astronomy Meeting in Dublin on Wednesday April 9th by Dr Aaron Romanowsky of the University of Nottingham.
Spectacular VLT Photos Unveil Mysterious Nebulae
Quite a few of the most beautiful objects in the Universe are still shrouded in mystery. Even though most of the nebulae of gas and dust in our vicinity are now rather well understood, there are some which continue to puzzle astronomers.
This is the case of a small number of unusual nebulae that appear to be the subject of strong heating – in astronomical terminology, they present an amazingly “high degree of excitation”. This
Has an increasing trend in the Suns brightness contributed to global warming over the last few decades? One study published recently says it has but Judith Lean of the US Naval Research Laboratory will tell a joint session of the UK/Ireland National Astronomy Meeting and Solar Physics Meeting in Dublin that a different study has come to the opposite conclusion when she tackles the controversial topic of the relationship between our climate and the Sun on Tuesday 8 April.
Earths
A team of astronomers based in the UK and the US has for the first time measured the redshifts of a significant sample of puzzling “submillimetre galaxies”, discovered by some members of the team in 1997. Dr Ian Smail of the University of Durham will tell the UK/Ireland National Astronomy Meeting that these are remote galaxies with high redshifts, and are likely to contain huge numbers of young stars heavily enshrouded by dust. Because of the time it takes light to travel, they are seen how they were
When Gerald A. Miller first saw the experimental results from the Thomas Jefferson National Accelerator Facility, he was pretty sure they couldnt be right. If they were, it meant that some long-held notions about the proton, a primary building block of atoms, were wrong.
But in time, the findings proved to be right, and led physicists to the conclusion that protons arent always spherically shaped, like a basketball.
“Some physicists thought they did the experiment wron
