Waspie_Dwarf Posted July 3, 2015 #1 Share Posted July 3, 2015 Astronomers Predict Fireworks from Rare Stellar Encounter in 2018 Astronomers are gearing up for high-energy fireworks coming in early 2018, when a stellar remnant the size of a city meets one of the brightest stars in our galaxy. The cosmic light show will occur when a pulsar discovered by NASA's Fermi Gamma-ray Space Telescope swings by its companion star. Scientists plan a global campaign to watch the event from radio wavelengths to the highest-energy gamma rays detectable.The pulsar, known as J2032+4127 (J2032 for short), is the crushed core of a massive star that exploded as a supernova. It is a magnetized ball about 12 miles across, or about the size of Washington, weighing almost twice the sun's mass and spinning seven times a second. J2032's rapid spin and strong magnetic field together produce a lighthouse-like beam detectable when it sweeps our way. Astronomers find most pulsars through radio emissions, but Fermi's Large Area Telescope (LAT) finds them through pulses of gamma rays, the most energetic form of light. Read more...

Zalmoxis Posted July 4, 2015 #2 Share Posted July 4, 2015 I didn't know what pulsars were. Thanks for the info. Link to comment Share on other sites More sharing options...
