Greatest X-Ray Space Observatories Ever

A comparison of the most impactful X-ray missions in history based on spectral resolution, mission longevity, and discovery rate.

The top 3

  1. Chandra X-ray Observatory: The GOAT: Launched in 1999, it maintains the record for the sharpest X-ray images ever taken, allowing astronomers to see deep into galactic centers. Chandra X-ray Observatory
  2. XMM-Newton: Highest Sensitivity: The European Space Agency’s flagship, it holds the record for the largest collective area of X-ray mirrors, providing the most data on faint high-energy objects. XMM-Newton
  3. XRISM: The New Resolution King: By integrating microcalorimeter technology, it achieves a resolution of < 5 eV, far surpassing the spectral capabilities of its predecessors in capturing gas dynamics. XRISM
