“We’ve calculated that by observing 50 binary neutron stars over the next decade, we will have sufficient gravitational wave data to independently determine the best measurement of the Hubble constant. We should be able to detect enough mergers to answer this question within 5 to 10 years.”
An astounding image of a bubble of newly forming stars in the Large Magellanic Cloud (LMC) has been captured by the Multi Unit Spectroscopic Explorer (MUSE) instrument aboard ESO’s Very Large Telescope (VLE). Researchers hope the observation will shed light as to the mechanism by which massive stars form.
An international team led by the University of Southampton has been observing a black spinning around its axis at its near maximum rate in our galaxy. It is hoped that the study will shed more light on the characteristics of black holes and their surrounding environment.
The most primary questions that remain in our understanding of the Universe, the nature of dark matter and dark energy, and the missing 95% of matter in the Universe, could have a related explanation, scientists at Oxford have suggested; a fluid containing ‘negative mass’
UK scientists have made the first observation of gas falling into a black hole at 30% of the speed of light offering support to the theory that misaligned gas discs around black holes can cause material to fall directly into the space-time event liberating huge amounts of energy.
The source of high-energy ‘cosmic neutrinos’ has eluded scientists for decades, that was until last September when such a particle struck a detector buried in ice at the South-Pole, research published in Science reveals. The event was coupled with the detection of a flaring ‘blazar’ by NASA’s Fermi Gamma-Ray Telescope giving us a clue as to the origin of high-energy neutrinos. This discovery is not just significant for our knowledge of these particles however, it may help usher in a whole new age of astronomy.
The consumption of stars by supermassive black holes which lie at the centre of most galaxies is believed to be a fairly common event in the Universe, but astronomers have been unable to observe such proceedings unfold. That was until recently. It was revealed today that scientists at Astrophysical Institute of Andalusia in Granada, Spain have used two specialised telescopes to observe the violent event in its full glory.
