Star factory

A gigantic star factory in the early Universe challenges galaxy evolution theory.

Acording to a study led by ESA’s Herschel space observatory and with the Spanish participation of the Astrofísica de Canarias &l Gran Telescopio de Canarias, an extremely distant galaxy has discovered. This galaxy makes stars more than 2000 times faster than our own Milky Way. Seen at a time when the Universe was less than a billion years old, its mere existence challenges our theories of galaxy evolution.

This research is published on the latest number of Nature magazine at Riechers et al. (2013), Nature  "A Dust-Obscured Massive Maximum-Starburst Galaxy at a Redshift of 6.34"
