Another black hole discovery using an observatory on Mauna Kea, this time the Kecks. This time it's a rogue supermassive black hole that's creating stars in its wake.
"Astronomers Spy a Giant Runaway Black Hole’s Starry Wake"
"A candidate “rogue” supermassive black hole may weigh as much as 20 million suns and has sparked a trail of star formation that is 200,000 light-years long"
"That black hole was discovered by chance when it first appeared as a faint linear streak in a Hubble Space Telescope observation of globular clusters. Such features are usually artifacts of cosmic rays striking Hubble’s detectors, explains lead study author Pieter van Dokkum, an astronomer at Yale University. Further observations via the ground-based W. M. Keck Observatory on Mauna Kea in Hawaii revealed instead that the streak was a stream of young blue stars stretching across an astonishing 200,000 light-years."

"Keck Observatory also showed a bright knot of ionized gas at the top of the wake – likely the site of the black hole itself. Also, the linear feature’s home galaxy appears to be missing a black hole at its center, or at least does not have one that is actively feasting on material and generating powerful jets of energy that telescopes can detect."
