Across the universe, unsuspecting galaxies are literally getting the life sucked out of them. Though the culprit is still at large, a team of researchers at the International Centre for Radio Astronomy Research (ICRAR) in Western Australia is working tirelessly to crack the case—and to restore law and order.
After examining 11,000 galaxies using the Sloan Digital Sky Survey and Arecibo Legacy Fast ALFA survey, the team concluded that a process called ram-pressure stripping—which forces gas out of galaxies—is more common than previously imagined.
