Kind: research · Impact: medium

## In brief

- Fourteen years of Fermi telescope data reveal around 450 gamma-ray sources in a largely unexplored energy range.
- The finding roughly doubles the number of known objects in this energy range.
- About 15% of the newly found sources are still unidentified.

## Why it matters

Gamma rays in this range come from extreme environments such as supermassive black holes and exploding stars, so the larger catalogue gives science readers a much bigger sample of these objects to study.
