...Since February of this year, Lucas Paganini, a NASA-affiliated astronomer at the Catholic University of America, has been doing just that—looking for Europa’s shadowy plumes in near-infrared light using one of the twin 10-meter telescopes at the Keck observatory on Mauna Kea in Hawaii.
“There are a lot of deniers of plumes out there, without real reason,” he says. “There is nothing crazy about saying plumes exist and are even common from icy moons. It’s not like anyone is trying to get famous from this, just by claiming detections.” In a preview of results to be presented at a meeting of the American Astronomical Society in October, Paganini says he has seen many “interesting things” in the Keck data, but nothing that would definitively rule out the latest reports of plumes—and nothing that would confirm them...
