The polarisation of the observed light in the extremely strong magnetic field suggests that the empty space around the neutron star is subject to a quantum effect known as vacuum birefringence, a prediction of quantum electrodynamics (QED). This effect was predicted in the 1930s but has not been observed before. The magnetic and electric field directions of the light rays are shown by the red and blue lines. Model simulations by\u00a0Roberto Taverna (University of Padua, Italy) and Denis Gonzalez Caniulef (UCL\/MSSL, UK) show how these align along a preferred direction as the light passes through the region around the neutron star. As they become aligned the light becomes polarised, and this polarisation can be detected by sensitive instruments on Earth.","src":"https:\/\/i0.wp.com\/hobbyspace.com\/Blog\/wp-content\/uploads\/2016\/11\/eso1641a1.jpg?resize=350%2C200","width":350,"height":200},"classes":[]},{"id":1550,"url":"https:\/\/hobbyspace.com\/Blog\/?p=1550","url_meta":{"origin":3511,"position":2},"title":"A new exoplanet finder mission in 2017","author":"TopSpacer","date":"April 7, 2013","format":false,"excerpt":"Good to hear that there will be a follow up mission to the Kepler space observatory dedicated to finding exoplanets: NASA chooses all-sky planet hunter, neutron star watcher for liftoff in 2017 - Cosmic Log NASA Selects Explorer Investigations for Formulation- NASA Update: Don't see a website for the exoplanet\u2026","rel":"","context":"In &quot;Astronomy&quot;","block_context":{"text":"Astronomy","link":"https:\/\/hobbyspace.com\/Blog\/?cat=12"},"img":{"alt_text":"","src":"","width":0,"height":0},"classes":[]},{"id":26394,"url":"https:\/\/hobbyspace.com\/Blog\/?p=26394","url_meta":{"origin":3511,"position":3},"title":"ESO: Observation of supernova producing compact object (black hole or neutron star)","author":"TopSpacer","date":"January 10, 2024","format":false,"excerpt":"A new report from the European Southern Observatory (ESO): Missing link found: Supernovae give rise to black holes or neutron stars Astronomers have found a direct link between the explosive deaths of massive stars and the formation of the most compact and enigmatic objects in the Universe \u2014 black holes\u2026","rel":"","context":"In &quot;Astronomy&quot;","block_context":{"text":"Astronomy","link":"https:\/\/hobbyspace.com\/Blog\/?cat=12"},"img":{"alt_text":"","src":"https:\/\/i0.wp.com\/hobbyspace.com\/Blog\/wp-content\/uploads\/2024\/01\/eso2401a-500x281.jpg?resize=350%2C200&ssl=1","width":350,"height":200},"classes":[]},{"id":1569,"url":"https:\/\/hobbyspace.com\/Blog\/?p=1569","url_meta":{"origin":3511,"position":4},"title":"ISS communications upgrade","author":"TopSpacer","date":"April 8, 2013","format":false,"excerpt":"The International Space Station is getting a big boost in communications bandwidth, which will greatly benefit the rapidly growing scientific work going on there: ISS gets communications overhaul to boost scientific output - NASASpaceFlight.com.
