It's story time at the Cool Worlds Lab as we recount the recent amazing tale of GW 170817. A tale of two cosmic siblings who lived, died and then finally merged together to create one of the spectacular astronomy discoveries of all time. Featuring massive stars, supernovae explosions, colliding dead stars and even dinosaurs (!) - sit down, relax and enjoy the tale of GW 170817...
