Cosmic Origins Spectrograph: Large Scale Structure of the Universe

🌌 How do you map the invisible skeleton of the cosmos?

The universe isn't just a random collection of galaxies; it's organized into a massive, web-like pattern known as the Large-Scale Structure of the Universe. But because the vast majority of this cosmic web is made of faint, invisible gas, scientists need specialized tools to see it.

Enter the Cosmic Origins Spectrograph (COS). Installed on the Hubble Space Telescope, COS acts like a cosmic prism, breaking down ultraviolet light from distant quasars. By analyzing how this light is absorbed by the intervening cosmic web, COS allows astronomers to map the "invisible" matter bridging the gaps between galaxies.

In this video, we explore how the Cosmic Origins Spectrograph works, how it helps us understand the filamentary structure of our universe, and what it reveals about the evolution of the cosmos over billions of years.
