Illustris Freeze Frame

Caption: This still frame from the Illustris simulation is centered on the most massive galaxy cluster existing today. The blue-purple filaments show the location of dark matter, which attracts normal matter gravitationally and helps galaxies and clusters to clump together. Bubbles of red, orange and white show where gas is being blasted outward by supernovae or jets from supermassive black holes.
