Cosmic Web Filament

Cosmic Web Filament

This deep image shows the nebula (cyan) extending across 2 million light-years that was discovered around the bright quasar UM287 (at the center of the image). The energetic radiation of the quasar makes the surrounding intergalactic gas glow, revealing the morphology and physical properties of a cosmic web filament. The image was obtained at the W. M. Keck Observatory. Credit: S. Cantalupo, UCSC
