This image of galaxy W2246-0526 was created using data from the Atacama Large Millimeter/submillimeter Array (ALMA) - a collection of individual radio antennas that work together as a single telescope. The galaxy is syphoning material away from three companion galaxies through trans-galactic streamers. The main galaxy and one of its companions are in the center. To the lower left is another companion and its large tidal tail that connects it to the main galaxy. The upper left concentration is the third companion galaxy. https://photojournal.jpl.nasa.gov/catalog/PIA22359
