Astronomers use galaxies to reckon a subatomic particles mass.
By mapping hundreds of thousands of galaxies, astronomers have estimated the mass of the neutrino. They have also calculated the contribution that this mysterious subatomic particle makes to the total mass of the Universe.
The neutrino weighs no more than one-billionth of the mass of a hydrogen atom, Ofer Lahav of the University of Cambridge told the annual UK National Astronomy Meeting in Bristol today. Yet
Astronomers may have discovered a strange new form of matter.
Astronomers think they might have spotted a quark star, a mass of fundamental particles only a few kilometres across but weighing more than our Sun. If the star’s nature is confirmed, it would be the first example of this state of matter.
Theoreticians hypothesized the existence of quark stars in the 1980s. Today, NASA announced the discovery of such a star, based on results from their space telescope the Chandra
Diseases involving irremediable tissue damage of the musculoskeletal system account today for about 15% of hospital admissions in developed countries. With the ageing of the population, this is believed to gain significantly in importance in the coming years.
The majority of the disorders affecting the musculoskeletal system are the joint diseases, in particular osteoarthritis. The latter disease process is typically initiated and associated with defects of the articular cartilage and the un
Scientists at the University of Plymouth have been developing methods to `close the loop` on waste and pollution, by finding waste products that can be used to improve soil / plant-growth conditions. At the Society for Experimental Biology conference in Swansea Dr Stuart Lane presented ways in which garden and industrial waste could be recycled to benefit the environment.
In collaboration with Ecological Sciences Limited, Dr Lane`s group investigated a horticultural growth substitute for pea
In a laboratory in Nottingham, scientists are now creating the uniquely harsh conditions encountered in interstellar space. In an environment where the pressure is only one ten billion billionth (one part in 10 to the power 13) of atmospheric pressure, and the temperature a mere 10 degrees above absolute zero, Dr Martin McCoustra and his colleagues are able to mimic the surfaces of the ice-coated dust grains in interstellar clouds and to study the complex chemical and physical processes that take pla
By using the Hubble Space Telescope (HST) as a `time machine`, astronomers from the Universities of Edinburgh and Oxford in the UK and the Space Telescope Science Institute (STScI) in Baltimore in the USA have been able to trace back the history of massive elliptical galaxies. They have found that galaxies of this kind, which still exist today, were already luminous families of stars about 10 billion years ago when the universe was only one third its present age. Their latest observations suggest tha
Under certain circumstances galaxies release huge quantities of matter into their environment, triggered by a large number of explosions of massive stars. The MUSE instrument of the Very Large Telescope…
