Specifically, they picked up a clear signal of tellurium, a heavy, mildly toxic element that is rarer than platinum on Earth but thought to be abundant throughout the universe. The astronomers estimate that the merger gave off enough tellurium to equal the mass of 300 Earths. And if tellurium is present, the merger must have churned up other ...Web
