Dark matter detected dangling from the cosmic web for 1st time

For the first time, astronomers have detected dark matter hanging from massive filaments that stretch across the universe and form a "cosmic web" that trap galaxies like morning dew on a spiderweb.

Researchers from Yonsei University in Seoul, South Korea, used the Subaru Telescope — an 8.2-meter optical-infrared telescope near the summit of Maunakea in Hawaii — and an effect that gravity has on light to indirectly observe dark matter sitting on cosmic web filaments in the Coma Cluster.
