How the largest star known is tearing itself apart

more »

(Phys.org) —An international team of astronomers has observed part of the final death throes of the largest known star in the universe as it throws off its outer layers. The discovery, by a collaboration of scientists from the UK, Chile, Germany and the USA, is a vital step in understanding how massive stars return enriched material to the interstellar medium—the space between stars—which is necessary for forming planetary systems. The researchers publish their results in the Oxford University Press journal Monthly Notices of the Royal Astronomical Society.
