<p>There is more to the violence of a black hole than the cataclysmic inward suck of infinite gravity. There is a yang to the yin of a black hole's inward attraction (accretion), which takes the form of relativistic jets that blast outward from the black hole stretching for sometimes millions of light-years. </p><p>A recent discovery, described in a paper published Friday in Science, offers a new perspective on these jets thanks to a passing star unfortunate enough to wander into the outflowing blast from a quasar (either a supermassive black hole or a binary black hole system found at the center of a galaxy) spotted by the All-Sky Automated Survey for Supernovae (ASAS-SN) project. The event is known as ASASSN-14li. </p>
