Astronomers report most ‘Outrageously’ Luminous Galaxies ever observed

The 50-meter diameter Large Millimeter Telescope is the largest, most sensitive single-aperture instrument in the world for studying star formation. Operated jointly by UMass Amherst and Mexico's Instituto Nacional de Astrofísica, Óptica y Electrónica, it was recently used to observe the most luminous galaxies ever seen.

The newly observed galaxies are about 10 billion years old and were formed only about 4 billion years after the Big Bang. In categorizing luminous sources, astronomers call an infrared galaxy “ultra-luminous” when it has a rating of about 1 trillion solar luminosities, and that rises to about 10 trillion solar luminosities at the “hyper-luminous” level...
