Along with colleagues from UC Santa Cruz, theteam used the Swope telescope at Las CampanasObservatory in Chile to discover the lightproduced by the merger, pinpointing the origin ofa gravitational wave signal less than 11 hours after itwas detected. They also obtained the earliest spectraof the collision, which may allow them to explainhow many of the universe’s heavy elements werecreated—a decades-old question for astrophysicists. Their discovery, named Swope Supernova Survey2017a (or SSS17a), is published in a quartet ofScience papers [http://science.sciencemag.org]. Neutron stars are the incredibly dense remnantsleft behind after supernova explosions. Theoreticalastrophysicists have speculated for years about whathappens when two of them merge, but until nowthe phenomenon had never been witnessed. “They are as close as you can get to a black holewithout actually being a black hole,” explainedCarnegie’s Tony Piro, the Carnegie team’s leader. “Just one teaspoon of a neutron star weighs as muchas all the people on Earth combined,” he added. Carnegie’s scientists were alerted to the eventby the Laser Interferometer Gravitational-Wave Observatory (LIGO), which detects gravitationalwaves, ripples in space-time, caused by distantcosmic events. In February of last year, theLIGO project announced the first detection ofgravitational waves caused by two black holes merging—a discovery that was awarded the NobelPrize in Physics earlier this month. While the LIGO black hole discovery markedan important milestone, black hole mergers do notemit light and are therefore invisible to telescopes. Neutron star mergers, however, have long beenexpected to produce both light and gravitationalwaves, so the detection of these events was eagerlyanticipated. “The ability to study the same event with bothgravitational waves and light is a real revolutionin astronomy,” Piro said. “We can now study theuniverse with two completely different probes, which teach us things we could never know withonly one or the other.” CHRISTOPHER Nyerges THE ROOTS OF HALLOWE’EN Is it possible to observe a pre-commercialized version?
