This artist's impression shows galaxy WISE J224607.55-052634.9 (W2246-0526 for short), the most luminous galaxy ever discovered. A new study using data from the Atacama Large Millimeter/submillimeter Array (ALMA) shows that W2246-0526 is syphoning dust and other material from three of its smaller galactic neighbors. https://photojournal.jpl.nasa.gov/catalog/PIA22358
