Most Luminous Galaxy is Eating Its Neighbors (Artist's Impression)

Nov 15, 2018
This artist's impression shows galaxy WISE J224607.55-052634.9, the most luminous galaxy ever discovered.

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.

ALMA, an international astronomy facility, is a partnership of Europe, North America and East Asia in cooperation with the Republic of Chile. ALMA construction and operations are led on behalf of Europe by European Southern Observatory, on behalf of North America by the National Radio Astronomy Observatory (NRAO), and on behalf of East Asia by the National Astronomical Observatory of Japan (NAOJ). The Joint ALMA Observatory (JAO) provides the unified leadership and management of the construction, commissioning and operation of ALMA.

The National Radio Astronomy Observatory is a facility of the National Science Foundation, operated under cooperative agreement by Associated Universities, Inc.
