Dark matter, though invisible, weaves a vast cosmic web that binds galaxies together. For the first time, astronomers have captured a sharp image of one of these filaments, stretching 3 million light-years through space.

The Multi Unit Spectroscopic Explorer (MUSE) is a panoramic integral-field spectrograph on ESO’s Very Large Telescope in Chile. It operates in the visible wavelength range and helps astronomers reveal objects that cannot be found in imaging surveys.
