This artist’s concept shows what happened when two massive clusters of galaxies, collectively known as MACS J0018.5+1626, collided: the dark matter in the galaxy clusters (blue) sailed ahead of the associated clouds of hot gas, or normal matter (orange); both dark matter and normal matter feel the pull of gravity, but only the normal matter experiences additional effects like shocks and turbulence, which slow it down during collisions.

This Hubble image shows IC 3430, a dwarf galaxy around 45 million light-years away in the constellation of Virgo. The color image includes both optical and near-infrared observations from Hubble’s Advanced Camera for Surveys (ACS). It is based on data obtained through two filters. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / M. Sun.

This Hubble image shows NGC 3430, a spiral galaxy some 100 million light-years in the constellation of Leo Minor. The color image was made from separate exposures taken in the visible and near-infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys (ACS). It is based on data obtained through two filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.
