See it on NASA's siteThis image is a frame from a computer simulation, illustrating the distribution of dark matter in the universe. Astronomers use such simulations, combined with observations like the 2-Degree Field Galactic Redshift Survey, to understand where dark matter resides. It helps explain why galaxies rotate and move in clusters as if unseen mass is present.
