Fiery collision


At the time of going to press, the Laser Interferometer Gravitational-Wave Observatory (LIGO) announced that, for the first time, gravitational waves have been detected from the collision of two neutron stars. Within hours of the discovery on 17 August, 70 instruments in space and on Earth had focused in on the location 130 million light-years away. The combined observations, which span

the electromagnetic spectrum, not only help confirm what physicists had theorised about colliding neutron stars, but represent a new era of astronomy – where data from traditional telescopes, neutrino detectors, and now gravitational wave observatories are shared and compared to glean even deeper insights into the nature of the universe.


Earlier in the month, LIGO scientists


Professor Kip Thorne, Professor Barry Barish and Professor Rainer Weiss were recognised by the Nobel committee for bringing to completion four decades of effort resulting in the observation of gravitational waves. Read more about the Nobel Prize in Physics in the news starting on page 4. Also in this issue, there are features discussing how quantum dots and OLEDs are competing for the display market (page 14), how high-power diode lasers are impacting the materials processing market (page 18), and the latest advances in photonic crystal fibres (page 22).
