UNAWE SpaceScoop - Fireworks in the Universe With a Record and a Twist

<p class="p1"><a href= "https://spacescoop.org/en/scoops/2115/fireworks-in-the-universe-with-a-record-and-a-twist/"> https://spacescoop.org/en/scoops/2115/fireworks-in-the-universe-with-a-record-and-a-twist/</a></p> <p class="p1">Gamma-ray bursts, or GRBs, are huge explosions at the heart of distant galaxies — in fact, the most energetic and brightest events in the whole Universe! These bursts can last from a few milliseconds to several hours. </p> <p class="p2"> </p> <p class="p1">Astronomers classify these events into two general categories:</p> <p class="p1">- Short GRBs that last less than two seconds and are believed to result from the merging of neutron stars. And…</p> <p class="p1">- Long GRBs that last longer than two seconds and are believed to start with supernova explosions, caused by the death of massive stars. </p> <p class="p2"> </p> <p class="p1">A team using the Gemini North Observatory has just found that gamma-ray bursts do not always fit the boxes astronomers have created for them. They saw a 0.6-second GRB coming from a supernova explosion in a distant galaxy. At less than 2 seconds duration it should be the result of a neutron star merger, not a supernova! So it’s the shortest ever seen of its kind!</p> <p class="p2"> </p> <p class="p1">We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.</p> <p class="p1">Just visit: <a href= "https://www.patreon.com/365DaysOfAstronomy">https://www.patreon.com/365DaysOfAstronomy</a> and donate as much as you can!</p> <p class="p1">Share the podcast with your friends and send the Patreon link to them too!</p> <p class="p1">Every bit helps!
