caption_attribution_description: English: This is the galaxy pair w:HXMM01, a w:gravitational lens in which two galaxies are rapidly colliding
context_page_description: HXMM01, known more formally as 1HERMES S250 J022016.5−060143, is a starburst galaxy located in the northwestern portion of the constellation Cetus. Discovered in 2013 by a team at the University of California, Irvine, it was discovered that HXMM01 is actually still forming from its two parent galaxies as part of the "brightest, most luminous and most gas-rich submillimeter-bright galaxy merger known." When the merger is complete, HXMM01 will rapidly evolve to become a giant elliptical galaxy with a mass about four times that of the Milky Way. As of 2013, HXMM01 has been observed to form about 2,000 M☉ of stars every year, with an efficiency ten times greater than that of typical galaxies and far more than the Milky Way's 0.68–1.45 M☉ per year.
