In A Galaxy Far Far Away
 In a Galaxy Far Far Away   Rob Gieselmann, Pent. 24A, Oct. 22, 2017     On August 17 of this year, astronomers observed the astounding collision of two neutron stars, in a galaxy far, far away . It all started when one telescope recorded a 100-second chirp two octaves above Middle C. This signal indicated something unexpected and dense like  a black hole, only not a black hole. Seconds later, another telescope a continent away recorded a twin signal – and taken together, these signals suggested two neutron stars spiraling around each other – much like twin blades of a kitchen blender.     A neutron star, by the way, is a star at the end of its life, close to becoming a black hole. It’s about six miles across, the length of Manhattan, yet so dense that a single thimbleful – weighs the same as several million elephants.     So imagine it: two of these neutron stars spiraling into each other - that is what astrophysicists witnessed, and for the first time ever, photographed their collisi...
