Description

At around 18 million light-years away in the constellation Triangulum, dark matter could be dominating the behavior of several galaxies. In a 2008 paper, astronomers Zitrin and Brosch observed that NGC 672, IC 1727, and 12 smaller galaxies all seem to be moving together with a long filament of dark matter stretching across 6° of sky, or 1.7 million light-years. NGC 672 and IC 1727 are the two largest galaxies. Scientists have analyzed the star formation within IC 1727 and NGC 672 and discovered that the observations show simultaneous bursts of star formation in the two galaxies occurred in the intervals 20-30 and 450-750 million years ago.
