Galaxies & Cosmic Structures

Phenomena operating across millions and billions of light-years — from feeding supermassive black holes to the enormous web connecting galaxies.

Galaxies are enormous collections of stars, gas, dust and dark matter held together by gravity. They are gathered into groups, clusters and a vast cosmic web, and many host supermassive black holes at their centres that can power some of the brightest objects in the universe.
