eROSITA (extended Roentgen Survey with an Imaging Telescope Array)

eROSITA (extended Roentgen Survey with an Imaging Telescope Array) is a space-based X-ray telescope designed to map the entire sky in high-energy X-rays. Its goal is to detect millions of galaxy clusters, active galactic nuclei, and other cosmic phenomena, helping scientists understand the universe's large-scale structure, dark matter, and dark energy. Mounted on the Spektr-RG satellite, eROSITA's sensitive instruments provide detailed images and data, enabling researchers to explore the distribution and evolution of cosmic objects over time. This comprehensive survey enhances our knowledge of the universe’s composition and the fundamental forces shaping it.
